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.
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 9-6
for shutdown
instructions.)
Remove the terminal block covers from the UPS system and
•
external battery cabinet.
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 7-3
and the external battery cabinet’s documentation for terminal
block diagrams. See
Section 7-4
for wiring diagrams. See
Section
7-5
for 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.
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.
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.
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.
