Step
1 Fasten mounting brackets (see Figure 4-2) onto the cabinet
with M12 bolts and washers (supplied in installation
hardware). Do NOT torque bolts yet. Align the cabinet over
the holes.
! CAUTION
Do NOT use the cabinet doors as a hand hold to move the
cabinet around, this could damage the door hinges
2 Install the anchor bolts in the four (4) mounting locations in
the mounting brackets attached to the cabinet base. Tighten
the bolts to proper torque recommended by the manufacturer.
n WARNING
Motorola recommended anchor bolts must be used to assure
safety in the event of an earthquake (CGDS97400036). These
bolts should be tightened to 80 N–m (60 ft–lbs.).
3 Tighten the M12 bolts attaching the mounting brackets to the
cabinet, torque to 135 N–m (100 ft–lbs) with a torque wrench.
4 Remove the four (4) eye–bolts (see Figure 4-2) on the top of
the cabinet, replace them with the bolts and washers supplied
with the installation hardware using a 24 mm (15/16") hex
driver, torque to 80 N–m (60 ft–lbs).
5 Install the wiring as described in Chapter 5 of this manual.
The isolation washers supplied in the hardware installation
kit are provided to give the installer the option of
electrically isolating the cabinet should the situation
require it. The use of the washers is not a requirement. The
grounding of each site is unique, and the isolation of the
cabinet is a site specific decision.
This section covers the step–by–step instructions for mounting the
batteries and heater pads into the Power Cabinet. The Power Cabinet
can accommodate a total of 12 strings of 2 batteries (24 batteries total)
and 12 heater pads (1 per battery string). The actual number of battery
strings and heaters installed depends upon system configuration. This
section reviews the procedure to install one (1) string of batteries and 1
heater pad. This should be repeated until all batteries and heaters are
installed.
