POWER SUPPLY
CONNECTIONS
Route the control cable from the power supply
tank through the connector opening labeled HV
POWER SUPPLY at the top right of the control
panel and connect to TB4 (see Figure 6 for TB4
location) of the Mother Board printed circuit as-
sembly as detailed in Table 1.
It may be necessary to remove the cable grommet
to fit the control cable through the opening. If so,
slide the grommet hardware onto the control cable
in the order shown in Figure 6 before pulling the
cable through the connector housing.
Tighten the cable grommet ensuring the grommet
spring makes 360° contact with the exposed braid
of the control cable fro maximum noise immunity.
INTERLOCK
CONNECTIONS
Interlock terminals are provided for external fans,
conveyors, etc. Section 9-3.5 of NFPA- 33 requires
that automatic electrostatic equipment be inter-
locked with the exhaust air and conveyor. These
terminals are factory jumpered for test purposes
and identified by orange wire. The corresponding
factory installed jumper must be removed when
installing the desired interlock.
Refer to system installation drawings, the sche-
matic in Figure 5, and the electrical system
connections shown in Table 2 to determine the
appropriate exhaust air and conveyor interlocks
for your system.
All electrical interlocks are externally activated
by dry contact closure to the interlock terminals.
The dry contacts of the external interlock device
should have a contact resistance of no more than
1000 ohms and a minimum current rating of 2
Amps. The combined series contact resistance
should not exceed 3000 ohms if multiple devices
are used in series.
Route the interlock wiring through the connector
opening labeled INTERLOCK I/O on the bottom
of the cabinet and make the appropriate connec-
tions as described above. Since the interlock
wiring will be carrying 120 volts AC it should be
run in con-duit.

The high voltage ON signal supplied
across terminals TB2 #3 to TB2 #5 or TB6
#3 to TB6 #5 MUST be a momentary con-
tact closure and not a maintained closure.
The overload circuit is inhibited as long
as the high voltage ON signal is supplied
and does not time-out until the signal is
removed. Therefore, if the HV ON contacts
remain closed, the power supply will not
overload.
