3.6 Control Cabling
On standard- and wide-width cabinets, cable entry may be from the top or bottom via conduit connected to the removable
plate. On reduced-width cabinets, only top entry is available.
Each cabinet battery contains a battery-interface board (BIB) connected in series. The interconnection cabling and
hardware are factory-supplied for connected/attached battery-cabinet systems. To connect stand-alone cabinets, observe
the following requirements:
• Cabling and hardware must be field-supplied.
• Use Belden9156 or equivalent wire.
• The total length of cable from the UPS to all battery-interface connections must be less than 1000ft (300m).
NOTE: Route control cables away from high-voltage cables and busbars.
NOTICE
Risk of improper installation. Can cause equipment damage. During system commissioning, the Vertiv
technician sets the jumpers on the external interface board (EIB) and battery interface board (BIB). If additional
battery cabinets are added to the system after commissioning, the jumpers on the EIB and BIBs must be reset
by a Vertiv technician.
The cable connects to TB1154 on the BIB, see Figure 3.7 on the next page.
To connect to the external-interface board (EIB) in the UPS, refer to the appropriate section for your UPS model:
• Connecting to Liebert EXL S1 on page 20
• Connecting to Liebert EXL on page 21
• Connecting to Liebert NX on page 22
• Connecting to Liebert NXL on page 24
