Emerson SERIES 600T manual Control Wiring, Battery Wiring, Discontinued Product

8.2. Control Wiring

Control wiring must be stranded and tinned and run in individual separate steel conduit. Control wiring must be separated from power wiring. In addition, each control wiring cable group should be run in a separate conduit to minimize control signal interference.

If your system has any installed options, special wire lists will be included in your Submittal Drawing Package. Contact your Liebert Sales Representative for assistance if the Submittal drawings have been lost or misplaced.

All control cable groups are connected to different Interface Modules (IFMs) inside the UPS. Figure 29 shows the typical location of each IFM inside the UPS. The position of a particular IFM may be different for your UPS, depending upon the model and the installed options.

NOTE

The UPS control and communication wiring are considered Class 2 circuits by NEC standards. However, NEC Class 1 wiring methods are required for these circuits to ensure proper operation of the UPS.

8.3. Battery Wiring

Power wiring to the Battery Cabinet connects positive, negative, and ground power cables from the Battery Cabinet to the associated UPS. Connection of the UPS to the Battery Cabinet serves to both charge and discharge the batteries (when needed). The battery disconnect (circuit breaker) requires a control cable. Liebert Battery Cabinets include power and control cables to join multiple cabinets together into a system. Additional (field-supplied) power or control wiring might be necessary to connect the battery cabinet system to the UPS. Refer to Figures 16-17.

DANGER

A BATTERY INTERCELL CONNECTION ON EACH TIER IS DISCONNECTED FOR SAFETY DURING SHIPMENT. DO NOT COMPLETE THESE CONNECTIONS. THE LIEBERT GLOBAL SERVICES REPRESEN- TATIVE WILL COMPLETE THESE CON- NECTIONS AS PART OF START-UP. AN IM- PROPERLY INSTALLED UNIT CAN RESULT IN INJURY TO PERSONNEL OR DAMAGE TO EQUIPMENT.

CAUTION

Be sure polarity is correct when wiring the Battery Cabinet to the connected equipment (positive to positive; negative to negative). If polarity is not correct, fuse failures or equipment damage can result.

CAUTION

DC power cables should be installed in conduit with conductors in matched pairs (positive and negative).

NOTE

Inspection of the battery installation is a service that can be provided by Liebert. A Battery Specialist can perform a detailed inspection of the entire battery system to ensure it meets current IEEE standards.

This inspection service is recommended because batteries are a critical part of the UPS system.
