PDU Care
Normally, PDU requires no maintenance and no calibration. It is recommended,
though, to periodically inspect PDU for overheating.
During its normal operation PDU may have elevated temperature which would feel
“
warm
”
to the touch, but not what is considered
“
hot.
”
If the PDU does feels
“
hot
”
to the touch (more than 70
0
C or 158
0
F), turn off PDU and disconnect equipment that
is powered by PDU immediately. First, verify that the total current load does not
exceed PDU
’
s maximum rating. Keep in mind that sometimes stated power rating of
equipment is
“
typical
”
rather than
“
maximum
”
-
it is prudent to load PDU to no more
than 75% of its capacity to accommodate for such situations. Then, check if the heat
dissipation of the PDU is obstructed by improper installations such as objects placed
on its top or lack of space around it for proper ventilation, or its placement in a small
confined space. If such problem is identified, correct it, let the PDU cool down and
turn it back on. Check within 30 minutes and then within an hour the temperature of
the PDU. If the PDU still feels
“
hot
”
to the touch, turn PDU off, disconnect your
equipment, and discontinue using PDU. For warranty or other repair contact factory
or its authorized distributors.

Thank you for buying CleanSweep
®
rack
-
mounted PDU (power distribution unit)!
Your new CleanSweep
®
PDU will provide your sensitive equipment with AC power
free from electromagnetic interference (EMI) and power line transients. Such
artifacts on power lines and ground cause numerous equipment malfunctions, in-
cluding lock
-
up, erratic response, software errors, and other often
“
unexplained
”
behavior. Excessive transients and noise can also cause damage to sensitive
components via induced electrical overstress (EOS). For more details on this subject

Safety First!
CleanSweep
®
PDUs operate with high voltage that, improperly installed or used, may
cause property damage, injury and death. Always observe safety measures when
using power line filters. Here are some of the key safety precautions you should
take:
WARNING
•
Do not exceed PDU
’
s maximum rating
-
it may cause overheating
•
Use PDU after the fuse or circuit breaker of no more than specified max. rating
•
Use only with the power cord supplied by manufacturer
•
This PDU is not for household use
•
PDU must be plugged into a properly wired grounding type outlet
•
No serviceable parts inside
-
do not open. High voltage is present inside.
Introduction
CleanSweep
®
EMI PDUs reduce noise on power lines providing clean power to your
equipment. High levels of noise (also called conducted
El
ectro
M
agnetic
I
nterference
-
EMI) interferes with normal operation of electronic equipment and
can cause physical component damage inside the equipment. Noise on power lines
is common in industrial and office environment and the only practical way to deal
with it is by using properly
-
designed filter which is a part of CleanSweep® PDU. In
addition to effectively suppressing EMI, OnFILTER
’
CleanSweep
®
PDU provides
advanced transient surge protection by reducing power line transients down to
insignificant levels surpassing conventional surge protection.
Installation
Proper installation of PDU helps to assure its continuous operation for a long time.
Please follow these requirements for installation:
•
Use PDU in a dry location away from debris and from the possibility of spillage,
including from cleaning
•
Ambient temperature at the place of installation should not exceed the range of
5
0
…40
0
C
•
Firmly fasten PDU in a
19”
rack using all four screw (supplied)
•
Install filter close to your equipment
•
Do not install PDU in small confined spaces with restricted air circulation in or-
der to avoid overheating. Allow some space on each side for proper ventilation

WARNING
•
Before attempting any electrical connection, verify that your power source, such
as electrical outlet or junction box, is correctly wired and properly grounded.
•
Do not use PDU without proper grounding! Failure to properly ground the PDU
may result in failure to ground your equipment, in unsafe situation that can
cause property damage and injury, as well as failure of PDU to perform.
•
Use only the power cable supplied with the PDU. Other cables that may look
very similar to the one supplied may not have the same voltage/current ratings.
To connect PDU follow the steps below:
•
Install PDU in a rack and firmly fasten its front panel to the rack
’
s rails using
supplied screws
•
Power down and unplug your equipment that will be powered by PDU
•
Connect supplied power cable to the inlet on the back of PDU
•
Plug the PDU
’
s cable into the power outlet
•
Turn power switch on PDU on
(“
RESET
”
position). The red light in the power
switch should light up indicating that it receives power
•
Plug your equipment into the outlet of PDU and turn it on

Advanced Transient Surge Suppression
Power line surge is a sudden high energy disturbance in line voltage typically lasting
less than one cycle which causes short high voltage increases (up to 3kV or even
higher). This may cause data corruption, equipment malfunction, equipment
damage and process interruption.
CleanSweep® PDU AREC144FG has two stages of transient surge protection. First
stage protects your equipment from long
-
lasting surges (typically lasting less than a
second). Special high energy absorbing MOV (Metal Oxide Varistors) installed
between Live
-
Neutral, Live
-
Ground and Neutral
-
Ground absorb surges with peak
current up to 22kA.
The second stage is most important. While
conventional
surge
protection
limits
transients by amplitude, this may leave your
equipment exposed to spikes up to 600V.
CleanSweep® PDU utilizes special unique
short transient suppressor circuit as a part
of its EMI filtering to limit power line transi-
ents to no more than 10V (typ.). The graph
on the right shows how CleanSweep® PDU
suppresses transient surge spike which
would go unnoticed by conventional surge
protection.
With these two transient suppression stages
working together your equipment is well
-
protected
.
Note that MOV may lose some effectiveness if there are many very strong surges;
however EMI filter protection (second stage) does not wear out.
Multiple Loads and EMI Filtering
When using more than one equipment plugged into CleanSweep® PDU output, keep
in mind that:
•
Total current consumption shall never exceed maximum current rating, and
•
There is no filtering or surge protection between the loads at the output
EMI filtering and surge protection are provided only between the inlet on the back of
PDU
-
and output connectors on the front panel. There is no filtering or other
protection between the outlets on the front of the PDU—they are simply connected
in parallel. If you have a known piece of equipment which is
“
noisy
”
it would be
better to power it up separately so that it won
’
t pollute the rest of equipment.

PDU Operation and Performance
CleanSweep
®
PDU provides several functions:
•
Distributes power to four loads
•
Serves as overcurrent protection (circuit breaker)
•
Blocks EMI from AC power lines and ground providing your equipment with clean
AC power
•
Uses advanced transient surge protection to protect your equipment from harm-
ful power line spikes
Overload Protection
CleanSweep® PDU AREC144FG is equipped with a built
-
in 15A circuit breaker on its
front panel. It is prudent to have typical load current of no more than 75% of the
circuit breaker
’
rating to avoid shutdown during occasional excessive current peaks
which may not be specified in your equipment
’
specification. Should the current
through the PDU exceed its maximum rated current, this circuit breaker will trigger
and disconnect power to PDU and to the equipment plugged into it. In this case do
not reset the circuit breaker until you unplug equipment that may contribute to ex-
cessive current consumption and wait a few minutes to let circuit breaker
“
cool off.
”
Circuit breaker can be reset by simply toggling switch on the front panel into Reset
(upper) position.
The red light in the circuit breaker is
“
On
”
when power is on. When power is off and
if circuit breaker cuts off power, the light will be off.
EMI Filtering
EMI filter incorporated into CleanSweep® PDU AREC144FG provides significant noise
suppression in several modes—differential (between live and neutral), common
mode (live and neutral to ground) and, uniquely, in ground line itself. Unlike
conventional EMI filters, CleanSweep® PDU offers effective noise suppression for real
-
life situations in real
-
life use. For technical details on this please see
OnFILTER Advantage App. Note

web site
