ELECTRICAL CONNECTIONS
The standard electrical requirement for the APM is 115V
50/60 Hz. Also available is 230V 50/60 Hz. Main supply
voltage fluctuations should not to exceed ± 10% on nominal
voltage. Connect APM to a dual pole external switch or
circuit breaker suitable for full disconnection. Locate this
switch or circuit breaker nearby. The control cabinet has
a bottom ½” knockout for power connection and bottom
3/4” knockout for individual purge point solenoid valves
(See Figure 4). Any additional knockouts, if necessary,
should be made on the bottom of the control cabinet. A
grounding block inside the control cabinet is provided for 3
wire purge point solenoid coils. Carefully study the wiring
diagram below (Figure 5) to avoid electrical short circuits.
Connect electrical wiring from each purge point solenoid to
the remote purge point solenoid plug-in connector screw
terminals (1 through 8) plus the grounding block. Normally,
the voltage of the remote purge point solenoid valves is the
same as the purger. However, if the purge point solenoid
valve coil voltage is different, simply remove and discard
the factory installed jumpers between terminals 13 & 14 and
15 & 16. Bring the purge point solenoid line (L1) connection
to terminal 14 and neutral (L2) to terminal 16.
