ELECTRICAL CONNECTIONS
The UPS and battery cabinets are supplied with battery terminals on the rear of
the UPS within a cable box. (see outline drawing) The cable box (gland plate)
can be removed to enable knockouts to be removed, or new holes drilled, to
secure the cables.
The cable sizes and distribution methods used during installation are subject to
local/national electrical codes of practice, and therefore are not detailed here.
Refer to the tables and wiring diagram in the UPS manual for your specific
model. Information is also provided on the battery cabinet rating plate. Rigid or
flexible conduit is recommended for all battery wiring.
The battery cabinet terminals will accept wire sizes up to the values below:
GXT6000 = 10 mm
GXT10000 = 16 mm
(75º C copper wire)
Terminal tightening torque is 40 cm-kg (35 in-lb).
In no case should the voltage drop on the battery cables exceed 2.0 volts at the
battery cabinet's rated load.
Properly grounded (earthed) equipment provide multiple benefits.
High quality ground (earth) connections are required for the equipment ground
conductors (protective earth) and grounding electrode conductor (power system
earth connection) to reduce electrical noise and provide for safe operation of the
UPS and connected loads. Conduit used alone without a grounding conductor
wire is not an acceptable connection. Size ground (protective earth) conductors
equal to circuit conductors.
