7-6 External Battery Cabinet Wiring

Warning: External battery cabinets vary. Read the external battery cabinet’s documentation before attempting to connect it to the UPS system. Use only external battery cabinets that have been approved by Tripp Lite.

Note: An external battery cabinet is required with models SU60KX and SU80KX. It is optional with models SU20KX and SU40KX. Contact Tripp Lite for external battery cabinet ordering information.

•1 De-energize all input and output (AC and DC) of the UPS system
and external battery cabinet, and confirm that the external battery
cabinet breaker switch A is off. (If the UPS system has already
been wired to an AC power source, see Section 9-6for shutdown	A
instructions.)

•2 Remove the terminal block covers from the UPS system and external battery cabinet.

•3 Connect the positive (+), neutral (N) and negative (-) UPS system connection terminals of the external battery cabinet to the corresponding positive (+), neutral (N) and negative (-) external battery connection terminals of the UPS system. See Section 7-3and the external battery cabinet’s documentation for terminal block diagrams. See Section 7-4for wiring diagrams. See Section 7-5for cable size requirements. Cabling should be protected by flexible conduit and routed through the appropriate knockouts in the terminal block cover. Warning: Observe proper polarity by connecting negative to negative and positive to positive. Failure to observe proper polarity will damage the UPS system and create a risk of personal injury and property damage.

•4 Connect the external battery cabinet’s grounding terminal A to the UPS system’s corresponding grounding terminal B with a 4 AWG (5.189 mm) ground cable. Keep the ground cable connected at all times after installation.

•5 Connect the UPS system’s grounding terminal A to your facility’s earth ground B with a 4 AWG (5.189 mm) minimum ground cable. Keep the ground cable connected at all times after installation.

•6 Replace the terminal block cover of the external battery cabinet. If you do not plan to wire the AC input/output of the UPS system at this time, replace the terminal block cover of the UPS system.
