Liebert Series 600T UPS, 65-225 kVA, Single Module 19
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.
