WARNING:

The Powerware 9335 UPS requires a neutral input power connection for proper operation. Internal input and output neutrals are permanently connected inside the cabinet.

WARNING:

An insulated grounding conductor must be provided per NEC.

4.If the installation is for a single utility feed with common rectifier and bypass input, proceed to step 7. For a separate bypass and rectifier input, proceed to step 5.

5.Remove the single feed bus bar jumper connections from between X6 and X7, Phase A, B, and C and discard them. They will not be used again.

6.Connect ground, phase A, B, C, and Neutral mains input power wiring from the source to the Mains input terminals (1A, 1B, 1C) on the In/Out Terminal Block. Phase A input connects to input terminal 1A, phase B to input terminal 1B and phase C to input terminal 1C. Refer to Appendix A of this manual for wiring and termination requirements and wiring access information. Note wiring connections for dual feed systems.

7.Connect ground, phase A, B, C, and Neutral power wiring from the output terminals (3A, 3B, 3C) on the In/Out Terminal Block to the critical load. Output terminal 3A connects to phase A of the load, output 3B to phase B and output 3C to phase C, respectively. Refer to Appendix A of this manual for wiring and termination requirements and wiring access information.

8.Secure the UPS by reinstalling the safety shield panels, and closing the front cabinet door, latching the cabinet door with the removable door handle.

2.2.4Installing Customer Connections

See Chapter 10, “Communications”

2.2.5Prepare for Installing Optional Accessories

NOTE: If you are installing accessories, including the Remote Emergency Power Off (REPO) switch, you must install conduit between each device and the UPS cabinet for wiring these options.

1.Be sure the UPS system is turned off and all power sources are removed. (See the operation section of this manual for shutdown instructions.)
