 INTRODUCTION

   

   To get the most out of your 8ZED Inverter, proper 
installation is critical. Please read the installation and 
operating instructions in this manual carefully before 
installing and using your 8ZED Inverter. Pay special 
attention to the CAUTION: statements in this manual. 
CAUTION: statements identify conditions or practices 
which could result in damage to your 8ZED Inverter or to 
other equipment. Proper procedures not followed could result 
in the warranty becoming void. 

   

   

INTRODUCTION 

   

   The power source must provide between 11 and 15 volts 
DC and must be able to supply sufficient current to operate 
the load. As a rough guide line, divide the power 
consumption of the load (in watts) by 10 to obtain the current 
(in amperes) that the power source must deliver. 

  

CAUTION:  The 8ZED Inverter should not be used while 
driving your vehicle using the alligator clips.
 

  

CAUTION:  The 8ZED Inverter must be connected only to 
batteries with a normal output voltage of 12 volts. The 8ZED 
Inverter will not operate from a 6 volt battery and will be 
damaged if it is connected to a 24 volt battery.
 

  

CAUTION:  Rechargeable batteries and devices with 
rechargeable batteries may not be suitable for use with the 
8ZED Inverter. The rechargeable batteries, recharging 
transformer and/or the 8ZED Inverter may be damaged when 
trying to recharge devices of 10 volts and higher. Refer to the 
manufacturers specifications when using these devices. 

 

   SUITABLE POWER SOURCE 

 

   In order to operate the inverter and supply power to an 
appliance a suitable 12V DC power supply is required. This 
can be a vehicle, boat or caravan battery, portable power 
pack or an independent 12V lead acid battery. For most 
applications, a deep cycle battery is recommended for best 
performance. 

 

  BATTERY OPERATING TIME 

   

   The typical vehicle battery has a minimum operating time 
of 1 to 2 hours, depending on the current use of the load 
being driven and the size of the battery. We recommend that 
the operator start the vehicle every hour to recharge the 
battery system. This will prevent unexpected shut downs of 
equipment and will ensure that there is always sufficient 
battery capacity to start the engine. 

  

   PLACEMENT OF THE INVERTER

 

  

   For best operating results, the 8ZED inverter should be 
placed on a flat surface, such as the floor or seat of the 
vehicle. The inverter should only be used in locations that 
meet the following requirements: 

  

A.)  DRY – Keep away from water. Do not allow water to 

drip or splash on the 8ZED Inverter. 

B.)  COOL – Ideal ambient air temperature should be 

between 10 degrees and 33 degrees C (50 degrees and 

90 degrees F). Do not place the inverter on or near a 
heating vent or any piece of equipment which is 
generating heat above room temperature. If avoidable, 
do not place the inverter in direct sunlight. 

C.)  VENTILATED – Allow at least two inches of 

clearance around the 8ZED Inverter for air flow. Do 
not place anything on or over the inverter during 
operation. Make sure that the air is allowed to circulate 
freely around the unit. 

D.)  SAFETY – Do not use the 8ZED Inverter near 

flammable materials or in any location which may 
accumulate flammable fumes or gases, such as the 
battery compartment of your car, truck, RV or boat. 
This product is not suitable for use while travelling 
using battery clamps. The length of the wire cables and 
battery clamps are not designed for this operation. If 
you wish to operate the 8ZED inverter while moving, 
it must be permanently mounted and wired. 

 

 

   CONNECTING TO THE POWER SOURCE 

  

   CAUTION:  Before making any connections ensure 
inverter is switched off and has no AC appliances plugged 
into the AC output sockets. 

•  Connect the ring terminal on the negative lead (Black) 

to the negative (Black) DC terminal on the back of the 
inverter. 

•  Connect the battery clip (Black) or ring terminal on the 

other end of the lead to the negative DC supply or (-) 
battery terminal. 

•  Connect the ring terminal on the positive lead (Red) to 

the positive (Red) DC terminal on the back of the 
inverter. 

•  Connect the battery clip (Red) or ring terminal on the 

other end of the lead to the positive DC supply or (+) 
battery terminal. 

 

 

 

 

 

FIGURE 1- Loosen the caps on the terminals and slide the 
lugs between the cap and the base. Then tighten firmly.

   “HARD WIRED” CONNECTION 

 

When mounting the inverter in a vehicle, caravan, boat or 
cabin it may be preferable to use longer DC battery cables 
than those supplied, so that the inverter can be placed in a 
more convenient, cooler or more protected location.

It is also recommended that a heavy duty battery switch with 
a current rating higher than the fuse (or combined fuses) be 
fitted in the DC positive (+) line close to the battery to allow 
the supply to the inverter to be switched off, this can also be 
achieved by using a circuit breaker which has a trip facility. 

  

Positive and negative cables should be run close together to 
reduce cable inductance, and be protected from damage by 
corrugated conduit. 

  

   GROUND CONNECTION 

  

   The chassis ground lug must be connected to a grounding 
point. In a vehicle, connect the chassis ground lug to the 
vehicle’s chassis. In a boat connect to the grounding system 
of the boat. In a fixed location connect to the ground. 

 

 

  

   OPERATING TIPS 

  

 

 

 

Most electrical tools, appliances and audio/video 

equipment have a label indicating power consumption in 
amps or watts. Add up the power consumption in those items 
you will be using simultaneously, keeping total below the 
8ZED Inverter size. If the power consumption is rated in 
amps, multiply by the AC volts (220/230/240) to determine 
the wattage. For example, a television rated at 0.9 amps will 
use approx 99 watts. For more information regarding the 
typical wattage draws of many appliances, refer to 8zed.com.  

  

   Resistive loads, such as incandescent lights, are the easiest 
for the inverter to drive, though larger resistive loads, such as 
electric stoves or heaters, require more power. Please make 
sure you choose the right 8ZED Inverter to suit the 
application you need in order to power the appliance 
continuously. Inductive loads, such as TV’s and stereos (any 
device with a coil or a transformer in it) require more current 
to operate than a resistive load of the same power rating. 
Induction motors (motors without brushes), as well as some 
televisions, may require 2 to 6 times their power rating to 
start up. This condition may require repeated “ON/OFF, 
ON/OFF, ON/OFF” switching of the power switch on your 
8ZED Inverter in order to get them started. The most 
demanding are those that start under load, i.e. compressors 
and pumps. Since motor and television characteristics vary 
widely, only experimentation will determine if a specific load 
can be started and how long it can be run. 

    

   There are no standards for “surge power” partly because it 
can not be simply represented by a single sample number. 
Though our 8ZED Inverters can provide power up to 6000W 
(depending on the unit you purchase) for a short period, 
experimentation is the only method of determining whether it 
can handle the surges generated by a particular load. 

  

IMPORTANT NOTE: The 8ZED 120W to 1200W 
Inverters won’t operate most appliances designed to produce 
heat such as hair dryers, coffee makers, irons, heaters and 
toasters. The current use of most of these exceeds 1200 watts, 
far beyond the capacity of the units listed above. The inverter 
may be used either while the engine is running or turned off. 
However, the inverter may not operate while the engine is 
starting, since the battery voltage can drop substantially 
during engine cranking. The 8ZED Inverter draws less than 
1.3 ampere from the battery when it is not supplying power 
to the load. In most cases, the 8ZED Inverter may be left 
connected to the battery when it is not in use, since it draws 
so little current. If the vehicle will not be used for several 
days, disconnect the 8ZED Inverter from the battery. 

  

   CONNECTING APPLIANCE &    
   RUNNING INVERTER 

  

•  Connect the appliance AC plug to the inverter AC 

outlet socket. 

•  Switch the inverter “ON”, the Green power light will 

illuminate to indicate operation. 

•  Turn the appliance “ON”, if the appliance is fitted with 

an “On/Off” switch always switch the inverter on 
before switching the appliance on and always turn the 
appliance off before switching the inverter off. 

•  When not in use turn the inverter off. 

 

 

   LOW BATTERY ALARM 

 

 

   An alarm will sound when the voltage of the battery drops 
to 10.5 volts. This indicates that the battery requires 
recharging. The user should stop operations at this time, 
since the 8ZED Inverter will shut down automatically when 
battery voltage drops to 10.0 volts.

   If the low battery alarm sounds when the battery is fully 
charged, follow these steps for correcting the lack of output 
power: Reduce the load on the inverter and keep the voltage 
above 11.5 volts to maintain regulation. The alarm will sound 
when the inverter is overloaded, or if there is an excessive 
voltage drop between the battery and the inverter. 

  

NOTE: The alarm may sound momentarily when the unit is 
being connected to, or disconnected from, the power source. 
This is normal and does not indicate any problem.
 

  

   INDICATORS AND CONTROLS 

  

 

 

  

    PROTECTION FEATURES 

    

   Your 8ZED Inverter circuitry constantly monitors the 
following hazardous conditions: 

 

 

A.)  Low Battery Voltage – This condition is not harmful to 

the inverter, but could damage the power source. An 
audible alarm is sounded when input voltage drops to 
10.5 volts. When the condition is corrected (i.e. 
alternator charges battery) the unit may be restarted. 

 

B.)  Short Circuit - Reverse polarity or short circuit 

condition of the load will usually result in opening of 
the short circuit protection and blowing the three 35 
amp fuses. 

 

C.)  High Temperature – When the temperature of the 

internal heat sinks reaches 66 degrees C (150 degrees 
F), the solid state temperature sensor located in the 
8ZED Inverter will automatically shut down the unit. 
Once it is allowed to cool, it may be restarted.  

 

   TROUBLESHOOTING GUIDE / FAQ 

 

   Q. The inverter will not run my appliance even though 
the listed power is less than the inverter size 

 

   A.  Electrical appliances can be separated into three loads 
by the way they draw energy (current) from their power 
supply. These loads are “Resistive”, “Inductive” and 
“Capacitive” appliances. Some appliances may draw all three 
types of power, in which case all should be considered. 
•  Resistive Loads such as normal incandescent lights 

(wire filament) always draw a constant power (watts) 
from the power supply, that is a 100 Watt light will draw 
approximately 100 Watts from the power supply at all 
times. Resistive loads are the easiest appliances for an 
inverter to run. 

•  Inductive Loads such as a fridge (electric motor) require 

a large rush of power (surge current) to start and then 
usually draw a more constant power once running. 
Inductive loads contain coils of wire (motors, 
transformers, ballasts, solenoids). When the power is 
first turned on these coils of wire draw a large surge 
current which forms the magnetic flux which allows 
these appliances to work. The magnetic flux is a kind of 
stored energy. Most common inductive appliances are: 
fridges, air compressors, transformers, pumps, power 
tools & fluorescent lights. These appliances can draw 2-6 
times their normal running power to start up. To run a 
200 Watt fridge you may need a 600 to 1200 Watt 8ZED 
inverter. 

•  Capacitive Loads such as TV’s may require a large 

surge current to start only when they have not been used 
for a while. This is often due to large capacitors in the 
power supply that must be quickly charged when the 
appliance is turned on. If the appliance is not used for a 
few days these capacitors slowly go flat. Resetting the 
inverter a couple of times may allow these appliances to 
work. 

•  Some appliances such as large fridges, air conditioners 

and other pump driven appliances have extremely high 
start up currents, because they have an inductive motor 
that must start under load. These appliances are not 
recommended for use with an inverter. They should be 
powered by an engine driven generator.  

 

Q. Why is it important to make sure that the battery 
leads are not connected back to front? 

 

   A. The 8ZED inverter uses highly developed electronics to 
convert DC battery power to AC mains power. If you 
accidentally connect the inverter to the battery incorrectly a 
large current will be drawn by the inverter which will blow 
the protection fuses, as this occurs some of the high current 
could damage the sensitive electronic components. Because 
of this risk it is important to always double-check the battery 
polarity before making any connections. 

 

Q. Why do some power tools not work properly? 

 

   A.  Some newer power tools use PWM variable speed 
controllers to vary the tool’s speed as the trigger is squeezed. 
These power tools switch the power on and off very quickly 
in a similar way to how the inverter works. Because of this, 
some may not function properly with the inverter’s modified 
sine wave output. 

 

Q. Can I connect lights with dimmers to the inverter? 

 

   A.  Older light dimmers may function fine but most newer 
light dimming circuits are designed for household sine wave 
AC power, these may not work properly with modified sine 
wave inverters.
