CAUTION

• The 963 is designed for use in those areas using AC 120V electrical service,

while the 963E runs off of DC24V power, supplied by a universal power
supply capable of converting AC 100-240V electrical service. Usage of
either unit with the incorrect electrical voltage could result in incorrect
performance and an unsafe operating condition.

• The 963/963E has no user-serviceable parts. Do not remove the grill or

disassemble the unit in any way. If service other than that recommended in
this manual is needed, please contact 3M for information. UNAUTHORIZED
SERVICE WILL VOID THE WARRANTY.

• The 963/963E is NOT designed for usage in hazardous environments where

the possibility of explosion or fire exists.

• When cleaning the 963/963E housing or emitter points, verify that the unit is

off and disconnected from electrical power. Collected dirt on this unit should
be removed regularly to prevent accumulation that may result in fire.

• Class 1 equipment.

Safety Information

Intended Use

The 3M™ 963/963E Benchtop Air
Ionizer is designed to generate and
deliver a stream of ionized air. Its
intended use is to neutralize excess
static electricity buildup on electronic
devices and work surfaces. It is meant
to function as a stand alone device.

The 963/963E Benchtop Air Ionizer is
not intended to supplant proper
grounding of personnel as the
preferred method of controlling
electrostatic buildup and preventing
hazardous discharge.

Section 1.
Description

The 3M 963/963E Benchtop Air
Ionizer is a self-contained ionizing air
blower designed to remove static
charges from non-conductive objects.
The proprietary circuitry contained in
the blower generates equal levels of
positive and negative ions, and
maintains correct balance despite
variations in line voltage, fan speed,
and emitter point condition. The
963/963E is equipped with a two-
speed fan which allows the user to
select the amount of ionized air to be
delivered to the target object. In
addition, the housing of the 963/963E
is constructed of a static-dissipative
plastic, which minimizes the amount
of static charge that can buildup on the
outside surface of the unit.

Section 2.
Performance

The 963/963E Benchtop Air Ionizer
reduces a static charge of ± 1000 V to
± 100 V in less than one second (the
discharge time) at a distance of one
foot (30 cm) using the high fan speed.
Testing is performed in accordance
with the ionization standard
ANSI/ESD S3.1 and IEC standard
61340-5-1.

Section 3.
Power Requirements

The 963 requires AC 120V power and
is supplied with a 6 ft. (1.8 m) power
cord with North American style three-
prong plug. The 963E requires DC

24V power, which is supplied through
a Mini DIN connector on the back of
the unit. The 963E is packaged with a
universal power supply, capable of
converting AC 100V-240V, 50/60 Hz
into DC 24V. The universal power
supply uses a 3' (0.9 m) cord to
connect to the ionizer, and has an IEC
320 input socket for incoming power.
Please note that, due to the multitude
of locations worldwide in which the
963E can be used, it does NOT come
supplied with a power cord to connect
the universal power supply to local
electrical service. The customer is
asked to please provide an appropriate
power cord that is capable of
connecting local electrical service to
the universal power supply.

Section 4.
Installation

4.1 The 3M 963/963E Benchtop Air

Ionizer mounts easily in a variety
of positions using the provided
tilting bracket/stand. Place the
unit on the work surface and point
it at the area or object to be
neutralized. Alternatively, the
mounting bracket may be attached
directly to or above the
workstation, or on another
supporting structure. Please note
that placement of the 963/963E is
important in determining its
effectiveness. The distance from
the target object, and fan speed
affect the ionizer’s performance.
As distance increases or fan speed
is reduced, the discharge time will
increase.

4.2 Determine the location of an

appropriate electrical outlet. For
the 963, connect the power cord to
the ionizer, and insert the other end
of power cable into the appropriate
electrical outlet. For the 963E,
connect the universal power supply
to the ionizer, using the Mini DIN
connector. Then, using the
appropriate electrical power cord,
connect the universal power supply
to an electrical outlet.

Section 5.
Operation

The three position rocker switch on the
front of the unit is the POWER switch.
The center switch position (marked

)

is the OFF position. The upper and
lower switch positions (marked

and

) turn the unit on to HIGH and

LOW fan speeds. Use this switch to
turn the unit on and to select the desired
fan speed. A green monitor light is
also illuminated on the front of the
unit, which indicates that the power
switch is in one of the ON positions,
and that the ionizer is now in use.

Section 6.
Maintenance

Occasional cleaning of the case and of
the emitter points are the only routine
maintenance procedures required.

6.1 Cleaning the case: wipe the case

with a soft cloth moistened with
water. If a stronger cleaning
solution is required, mild
detergent or alcohol may be used.
Do not use solvents that will
attack the plastic case.

6.2 Cleaning the emitter points: when

the emitter points become dirty,
the internal circuitry of the ionizer
will be automatically adjusted to
emit an equal amount of positive
and negative ions. Contamination
on the needlepoint, however, may
inhibit ionization to a limited
degree. The emitter points are
located between the fan blades
and the rear grill. A jet of clean,
compressed air can be used to
remove dirt on emitter points. If a
more rigorous cleaning method is
needed to remove particulate,
clean the points with a cotton
swab. Access to the points is
available through the rear grill.
Be careful not to damage the
points during cleaning.

Section 7.
Performance Verification

The 963/963E Benchtop Air Ionizers
are factory adjusted to provide
optimum performance. Further
adjustment in the field is not possible.
However, the following instructions
can be followed to determine whether
the Ionizer is performing to
specification. The testing follows the
procedure outlined in the standard for
Ionization, ANSI/ESD S3.1. Please
refer to this standard for more
complete information.

7.1 Equipment Needed

3M 711 Charge Analyzer or
equivalent charge plate monitor
(CPM). If an alternate CPM is
used, please refer to its Operating
Manual for details on how to
perform the following instructions.

7.2 Static Discharge Time

The 963/963E Benchtop Air
Ionizer will reduce the charge on
the 6" x 6" square isolated metal
plate on the CPM from ± 1000
volts to ± 100 volts in less than 1
second (High fan speed). The
metal plate for the CPM must be
located at a distance of one foot
(30cm) from the ionizer and
centered in the air stream.

7.21 Attach the flat plate electrode to

the 711. Refer to the owner's
manual for the 711 for complete
operating instructions.

7.22 Place the 711 on its side allowing

for viewing of the display.
Position the 711 so that the plate
is parallel to the ionizer at a
distance of one foot. The plate of
the 711 should be centered (up &
down, left & right) in the air
stream. It may be necessary to

raise the ionizer from the surface
to allow for centering on the
711charge plate. If so, use a
block of appropriate height to
elevate the 711. Please note that
the plate must be kept totally
isolated from ground and that the
edge of the plate should be raised
up a minimum distance of 3
inches from the work surface.
This is illustrated in Fig. 11 of
ANSI/ESD-S3.1.

7.23 Turn on the ionizer at high speed

and allow it to run for five
minutes.

7.24 Charge the plate positive as

described in the 711 operating
instructions for "Static Decay
Time" mode. Observe the
discharge time indicated on the
711. Repeat this step for
negative polarity.

7.3 Ion Balance

The ionized air blower will stay
within an offset voltage of +/-15
volts (max. deviation from zero)
at a distance of one foot, when
measured using the following
procedure.

7.31 Position the ionizer and CPM as

stated above in Section 7.22.

7.32 Turn on the ionizer at high speed

and allow it to run for five
minutes.

7.33 Use a ground wire to ground the

charge plate of the 711. This will
remove any/all residual charge
present on the charge plate. If
the CPM does not zero, adjust
the zero control.

7.34 Remove the ground wire and

observe the display on the 711.
The voltage (either ±) observed
during this time is the "offset
voltage" and is a measure of
instantaneous ion imbalances
produced by the ionizer.
