III) INSTALLATION
A) Materials Provided
Prior to installation, check to ensure that each of the following items
have been included with the packaging. For any missing items
please contact the factory or warehouse.
(2) ea. mounting brackets for 19” rack mounting
(2) ea. mounting brackets for 23” rack mounting
(6) ea. 6-32 X 3/8” pan head phillips screws, black
(1) ea. Molex “pigtail” connector
(1) ea. Installation/Operation manual
(1) ea. Customer Satisfaction/Warranty card
(1) ea. Output Terminal Cover
B) Mounting
The PM is designed for various mounting options. Hardware for 19”
or 23” rack mounting is included
The PM is provided with two sets of mounting brackets and six 6-32
x 3/8” pan head phillips screws for attaching the brackets to the
PM chassis. Select the appropriate bracket set for the 19” or 23” rack
and fasten to the PM. Bracket attachment holes in the PM chassis
are provided to allow for 6” forward mounting only.
C) A.C. Input Wiring
Input Voltage:
the PM is designed to accept 207-253 VAC, 50/60
HZ, single phase input.
FIGURE 3: a.c. Input Wiring Compartment (PM rear view;
2,500 watt series)
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)
PM-48-50 #8 (10 mm)
PM-24-80 #4 (25 mm)
