Output Wiring Installation
1. Refer to Fig 4-6. Remove the four screws holding the out-
put wiring entry panels to the rear of the Power Array. Re-
move only the screws indicated in the illustration. Set the
screws and both panels aside temporarily.
2. Pull the L1, Neutral, and Ground wires through conduit,
leaving about 51.3 cm (20") of wiring extending from the
end. Install a flexible metal conduit connector to the end of
the conduit. Using appropriate tools, remove the knockout
in the entry panel. Feed the wires through the entry panel,
and attach the flexible metal conduit connector to the panel.
Strip 13 mm (1/2") of insulation from the end of each of the
incoming wires.
3. Connect output wiring to the output terminal connec-
tions as shown in figure 4-7. Make sure there are no loose
strands and that the terminal connection screws are suffi-
ciently tightened.

4. Carefully fold the excess wiring into the entry compart-
ment. After the electrical wiring test/checklist at the end of
this chapter is completed, replace the input wiring panels.
Output Wiring
n Read this chapter completely before installing wiring.
n Verify that all incoming line voltage (mains power)
and low voltage (control) circuits are de-energized and
locked out before installing cables or making connec-
tions, whether in the junction box or to the
Symmetra
TM
Power Array.
n Always verify that all battery modules are removed
and all battery extension frames are disconnected from
the Power Array before installing wiring.
Output voltage is delivered to the load equipment via
hardwired connections and/or via eight IEC 320 C13 power
outlets at the rear of the Power Array. To facilitate mainte-
nance and service of the Power Array, use flexible metal con-
duit for all hardwiring connections.
See table 4-2 for output wiring specifications.
