6.7Input and Output Wiring

NOTE

Input wiring must be installed using conduit.

208 input voltage jumper—if only the connections for 208 VAC are made between the UPS and theNfinity Maintenance Bypass, the 208 input voltage jumper must be installed for proper operation. To install this jumper, place the jumper wire provided in the accessory kit between Pin 1 and Pin 2 on TB4.

To connect the input wiring:

1.Locate the input wiring access (see illustration at right).

2.Remove the knockout and pull the three/four input wires through it, allowing some slack for installation.

3.Secure the conduit to the rear panel of the Maintenance Bypass Cabinet.

4.Input power cables connect to hex terminals on the input terminal block.

5.Insert the ground (earth) wire through the earth lug and tighten it to the proper torque value (120 in-lb). Then connect the wires to the block connections as shown at right. Using a torque wrench, turn the screws clockwise until tightened to the proper torque value (50 in-lb).

NOTE

The Nfinity UPS and Maintenance Bypass with transformer contain an isolation transformer that generates a neutral conductor for the connected equipment. The UPS and Maintenance Bypass with transformer are a separately derived source and contain a neutral-to-ground bonding jumper. A grounding electrode conductor (GEC) must be installed in accordance with national and local wiring codes and regulations.
