Operator’s Manual
1.2.3 From the disconnect box, install conduit to the power supply site and turn a stub up
to extend above grade level. Drive a suitable ground rod according to local codes
(refer to Figure 1.2-1).
1.2.4 Install appropriate size conduit for the output connections and turn a stub up to ex-
tend 1" above the pad surface cast into the concrete. Make sure to match conduit
locations with the appropriate cabinet locations; these locations are indicated in
Figure 1.2-1.
1.2.5 Using appropriately sized lumber, construct a form for the cement pad (refer to
Figure 1.2-1 for dimensions). Anchor the form securely to the ground. If a pre-
formed pad is utilized for the mounting of the CPR cabinet, check the bolt patterns
for proper alignment before anchoring the pad to the ground.
1.2.6 Attach the ground mounting brackets from the supplied hardware to the ground
skirt using the 5/16-18 X .75 screws and 5/16-18 nuts. Tighten securely.
1.2.7 Make a template from sheet metal or wood indicating the position of the ground-
mounting bracket mounting holes.
1.2.8 Drill out the two holes in the template and insert two 5/8" X 4" (M16-2.0 x 100mm)
bolts (not supplied). The heads of the bolts will be embedded into the concrete pad
when installation is complete. Leave sufficient thread above the pad for securing
the ground skirt.
1.2.9 Center the template (with holes in position) over the form. Be sure the conduit stub-
ups for the AC input, ground rod, and AC output are positioned at the desired loca-
tions just outside the ground skirt. Optional: The conduit stub-ups may pass
through the cement pad as shown in Figure 1.2-1 below.
1.2.10 Pour, level, and finish concrete to the bottom of the template. Allow a curing time of
24 hours.
1.2.11 Attach ground skirt to power supply cabinet. Align skirt inside bottom lip of the
cabinet and secure using 10-32 X 3/8" screws from the parts kit
1.2.12 Attach the power supply cabinet to the concrete pad using 5/8" (M16-2.0) nuts (not
provided) through the ground mounting brackets. Tighten all hardware securely.
