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 & output wiring is rated correctly.
The current spec, color, position, connection 8 and conductance
reliability of the wire should be verified. Make sure the L/N side is
correct, not reverse or short-circuited.
2.4 UPS Installation for Parallel System
If the UPS is only for single operation, you may skip this section.
1) Install and wired the UPS according to the section 2-3.
2) Connect the output wires of each UPS to an output breaker.
3) Connect all output breakers to a major breaker. This major output
breaker will then connect directly to the loads.
4) Either common battery packs or independent battery packs for each
UPS are allowed.
