2.2.2Installing External Battery Power Wiring

The Powerware 9335 contains no internal batteries and must therefore be used with an external battery system. The procedure for wiring the battery system to the 9335 is described as follows. Also read the manual provided with the battery system to ensure proper interconnections on the battery side.

1.If not already done, open the UPS cabinet door using the provided operator handle and remove the bottom internal protective panel. Retain hardware.

NOTE: Remove the UPS cabinet conduit landing plate to punch out conduit holes.

2.Route battery cables from the battery cabinet through the conduit landing plate at the UPS cabinet bottom rear to the battery terminals at the bottom front of the cabinet. Refer to Appendix A of this manual for wiring access information.

NOTE: Remove the UPS cabinet input and output conduit landing plate to punch conduit holes as required. When reinstalling, ensure that the protective ground wire is reconnected if it has been removed for conduit hole punching in the plate.

3.Connect positive, negative and neutral DC power wiring from the external battery source to the DC input (positive and negative) and neutral (battery center tap) terminals in the UPS cabinet. Refer to Appendix A of this manual for wiring and termination requirements and wiring access information.

2.2.3Installing UPS External Power Wiring

1.Open the front cabinet door using the provided removable operator handle (packed separately with the UPS). Remove the internal safety shield panel by removing the fastening hardware to gain access to the input and output terminals at the bottom front of the cabinet.

NOTE: Remove the UPS cabinet input and output conduit landing plate to punch conduit holes as required. When reinstalling, ensure that the protective ground wire is reconnected if it has been removed for conduit hole punching in the plate.

2.Route input and output cables through wireway to UPS terminal blocks. Refer to Appendix A of this manual for wiring access information.

3.For bypass input or single feed, connect phase A, B, C, Neutral (N) and earth ground

(G) input power wiring from the source to the bypass input terminals (2A, 2B, 2C) in the UPS cabinet. Refer to Appendix A of this manual for wiring and termination requirements and wiring access information. Note wiring connections for single feed systems.

DANGER:

Never connect the earth ground (G) to the Neutral connection (N) inside the UPS equipment cabinet. Never connect input and output neutrals (N) together. A serious electric shock hazard or equipment failure could result.
