7) To guarantee wire connection reliability, it is
necessary to put the cable gland cover back to
the rear panel of the UPS. Keep all cables
through the cable gland cover as shown in
below chart. Be sure that the length of output
wire cable is not over 3 meter. Cable gland size
of 6KB/6KS is M20 and the suitable diameter
of cable is 9-14 mm2.
Cable gland size of 10KB/10KS is M25 and the
suitable diameter of cable is 10-18 mm2
WARNING!
(Only for standard model)
• Make sure the UPS is not turned
on before installation. The UPS
should not be turned on during
wiring connection.
• Do not try to modify the standard
model to the long-run model.
Particularly, do not try to connect
the standard internal battery to
the external battery. The battery
type and voltage and numbers
may be different. If you connect
them together, it may cause the
hazard of electric shock or fire!
WARNING!
(Only for long-run model))
• Make sure a DC breaker or other
protection device between UPS
and external battery pack is
installed. If not, please install it
carefully. Switch off the battery
breaker before installation.
WARNING!
• For standard battery pack, there
are one DC breaker to disconnect
the battery pack and the UPS.
But for other external battery
pack, make sure a DC breaker or
other protection device between
UPS and external battery pack is
installed. If not, please install it
carefully. Switch off the battery
breaker before installation.
NOTE!
Set the battery pack breaker in
"OFF" position and then install the
battery pack.
• Pay high attention to the rated battery
voltage marked on the rear panel. If you want
to change the numbers of the battery pack,
please make sure you modify the jumper
setting on control board simultaneously. The
connection with wrong battery voltage may
cause permanent damage to the UPS. Make
sure, the voltage of the battery pack is
correct.
• Pay high attention to the polarity marking on
external battery terminal block, and make
sure, the correct battery polarity is
connected. Wrong connection may cause
permanent damage to the UPS.
• Make sure the protective earth ground wiring
is correct. The current spec, color, position,
connection and conductance reliability of
wire should be checked carefully.
• Make sure the utility input & output wiring is
correct. The current spec, color, position,
connection and conductance reliability of
wire should be checked carefully. Make sure
the L/N terminal is correct, not reverse or
short-circuited.
