Fire Hazard

Improper or inadequate opera-tion
and maintenance procedures will
cause a fire hazard.

Protection against inadvertent

fire or explosion is lost if any safety
interlocks are disabled during
operation. Frequent power supply
shutdown indicates a problem in
the system requiring correction.

SAFEGUARDSSAFEGUARDS

SAFEGUARDSSAFEGUARDS

Tells how to avoid the hazard.

Fire extinguishing equipment must be present in the
spray area and tested periodically.

Spray areas must be kept clean to prevent the
accumulation of combustible residues.

Smoking must never be allowed in the spray area.

The high voltage supplied to the atomizer must be
turned off prior to cleaning, flushing or maintenance.

When using solvents for cleaning:

Those used for equipment flushing should have flash
points equal to or higher than those of the coating
material.

Those used for general cleaning must have flash
points above 100oF (37.8oC).

Spray booth ventilation must be kept at the rates
required by NFPA-33, OSHA, and local codes. In
addition, ventilation must be maintained during
cleaning operations using flammable or combustible
solvents.

Electrostatic arcing must be prevented.

Test only in areas free of combustible material.

Testing may require high voltage to be on, but only as
instructed.

Non-factory replacement parts or unauthorized
equipment modifications may cause fire or injury.

If used, the key switch bypass is intended for use only
during set-up operations. Production should never be
done with safety interlocks disabled.

Never use equipment intended for use in waterborne
installations to spray solvent based materials.

The paint process and equipment should be set up
and operated in accordance with NFPA- 33, NED, and
OSHA requirements.

Halogenated hydrocarbon solvents
for example: methylene chloride
and 1,1,1,-Trichloroethane are not
chemically compatible with the
aluminum that might be used in
many system components. The
chemical reaction caused by these
solvents reacting with aluminum
can become violent and lead to an
equipment explosion.

Aluminum is widely used in other spray application
equipment - such as material pumps, regulators,
triggering valves, etc. Halogenated hydrocarbon
solvents must never be used with aluminum equipment
during spraying, flushing, or cleaning. Read the label
or data sheet for the material you intend to spray. If
in doubt as to whether or not a coating or cleaning
material is compatible, contact your material supplier.
Any other type of solvent may be used with aluminum
equipment.

(Reference NFPA- 33.)

A safe distance must be maintained between the
parts being coated and the atomizer bell. A distance
of at least 1 inch for each 10 KV of power supply
output voltage is required at all times.

Parts must be supported so that they will not swing
and reduce the clearance specified above.

All electrically conductive objects in the spray area,
with the exception of those objects required by the

Unless specifically approved for use in hazardous
locations, the power supply and other electrical
equipment must not be used in Class I, Division 1 or

System. It is unique in that it contains a built-in DC
Power Supply and is capable of operating either 1
or 2 MicroPak control units.

The MicroPak uses a combination of proven high

The current setpoint limits the maximum current
that the cascade can produce. The voltage
setpoint sets the maximum voltage the cascade
can produce. The MicroPak will first attempt to
achieve current output setpoint. If the voltage
setpoint is set low, then the voltage setpoint will not
allow the current setpoint to be achieved.

approved AC installation, however, if na­tional and local codes permit, the AC power
may be supplied via the factory supplied
line cord.

For installations where it is required to run the AC
input wiring in conduit, perform the following:

1. Ensure the AC line cord is unplugged and
remove the top cover from the controller (see
Figure 9).

4. Install the Conduit Adapter Plate (supplied)
(76453) in the hole where the AC Inlet Receptacle
was removed (see Figure 2).

The spray gun can be ordered with special low

splicing to a junction box. This is sometimes done
in the field, to reduce the amount of cable that has
to be replaced if a failure of the cable occurs. The

wire the junction box ends of these cables:

Junction Box in Hazardous LocationJunction Box in Hazardous Location

Junction Box in Hazardous LocationJunction Box in Hazardous Location

If the junction box is in the hazardous location, an
explosion-proof junction box must be used. In this
case, connect the numbered wires of cable
A11356-XX to the same numbered wire of cable
A11498-XX using a terminal strip inside the
explosion-proof junction box. Ensure the junction
box is grounded to earth ground. Connect wire 18
(braid) of cable A11498-XX to the junction box
(ground). Seal the cable in the explosion-proof
junction box using appropriate explosion-proof
fittings and sealing compound. The exposed area
of the cable braids must be located on the junction
box side of the sealing compound.

If the junction box is in a non-hazardous location,
then it is not necessary to use an explosion-proof
junction box. In this case, use the supplied cable
gland (A11357-02) and gland nut (A11358-02) to
secure the cables at their entry and exit to the
junction box. Install the cable gland in the junction
box and position the cable so that the spring of the
gland makes contact to the exposed braid of the
cable when the gland nut is tightened. Ensure the
junction box is grounded to earth ground. Connect
the numbered wires of cable A11356-XX to the
same numbered wire of cable A11498-XX using a
terminal strip inside the junction box. The braid of
cable A11498-XX will be grounded through its
contact to the cable gland spring and the grounded
junction box. Wire 18, therefore is unnecessary
and may be trimmed off. Connection in this
manner will ensure maximum noise immunity.
