WARNING (Standard Model Only)
• Make sure the UPS is off before the installation. The UPS should not be
turned on during wiring connection.
• Do not attempt to modify the standard model into the long-run model.
In particular, do not try to connect the standard internal battery to the
external battery. The battery type and voltage may be different, risk of
electric shock or fire may occur!
WARNING (Long Run Model Only)
• Make sure a DC breaker or other protective device between UPS and
the external battery pack is installed for added safety. 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 special attention to the rated battery voltage marked on the rear
panel. If you want to change the numbers of the battery in a chain,
make sure you modify the UPS setting accordingly. Connection with
wrong battery voltage may cause irreversible damage of the UPS.
• Pay special attention to the polarity marking on external battery
terminal block. Connection with wrong battery voltage may cause
irreversible damage of the UPS.
• Make sure the protective grounding/earthing wiring is adequate. The
current spec, color, position, connection and conductance reliability of
the wire should be verified.
• Make sure the utility input and output wiring is rated correctly. The
current spec, color, position, connection and conductance reliability
of the wire should be verified. Make sure the L/N side is correct, not
reverse or short-circuited.
