Step 3. Once the DCX unit is in it's nal position, mark the DCX
mounting bracket hole locations onto the battery stack frame top
rails (see Figure 10).
Step 4. Uninstall the termination plate from the battery terminals, then
uninstall the DCX mounting brackets from the DCX unit.
Step 5. Align the DCX mounting brackets with the marked locations from
Step 3 and secure into place by tightening the included self-
tapping screws (EnerSys/C&D/GNB battery kits, Figure 11) or by
tightening the included 1/4 in. hardware into the threaded inserts
of the mounting brackets (East Penn Manufacturing kits).
Step 6. Reinstall the DCX unit into position again as described in Step 2,
then tighten all hardware. See Table 4 for DCX mounting
bracket to DCX chassis torque specications.

CAUTION!
Two chassis ground landings are located on the inside of the DCX
chassis (see Figure 14). Refer to mechanical drawing found in
Appendix A.3 for greater detail regarding grounding locations. A
minimum of #6 AWG chassis ground cable is required. IMPORTANT:
Grounding hardware not included. A properly-sized grounding
conductor must be installed per NEC (250.122).

Step 1. Select the desired grounding location and break away the
associated knock-out points found on the clear plastic covers.
Step 2. Connect the ground cable with 1/4 in. hardware. Ensure heat
shrink and no-oxide compound are applied appropriately prior to
termination. Torque the fasteners to 5.83 ft·lbs (see Table 5).
