Chapter 4 - Electrical Requirements and Procedures

Output Wiring

nRead this chapter completely before installing wiring.

nVerify 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 SymmetraTM Power Array.

nAlways 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.

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.
