1) Replace the input wiring cover.
Important: Although the internal a.c. wiring is protected by the
front panel mounted circuit breaker, the wiring to the PM must also
be protected by wiring to an appropriate circuit breaker (30 Amp
double pole recommended for Line-Line AC sources).
D) D.C. Output Wiring
Important: Ensure that a.c. input to the PM is switched off before
working with d.c. wiring. The output terminals are "hot" whenever
the unit is switched on.
1) Output bus for hard-wiring of DC output are located on the rear
panel of the PM. Terminate wires with 1/4" ring lug connectors for
a secure installation. (Note: Output bus will accommodate 2 hole
lugs, 3/4" or 1" hole centers)
2) Use the chart below to determine minimum gauge for wires
depending on the particular model and the length of the run from
the PM to the load or distribution bus (or refer to N.E.C or local
codes for any questions regarding proper d.c. wire gauges).
D.C. Wire Size Table:
Model Minimum Wire Size per N.E.C. AWG (mm)
