● The UPS2000-G-6KRTLL needs to connect to external lithium batteries. Each UPS
supports a maximum of 16 batteries connected in parallel. This document uses four
lithium batteries connected in parallel as an example.
● If the UPS connects to only one lithium battery, the maximum load power is 4.0 kW.
● When lithium batteries are connected, it is recommended that a DC circuit breaker (150
A/80 V DC circuit breaker for the 6 kVA UPS) be installed between the lithium batteries
and the UPS.
● Before connecting cables to the UPS, ensure that the battery circuit breakers are OFF to
prevent operations with power on.
● If the UPS connects to multiple batteries,
congure the PE bar and battery busbar.
● If busbar terminals are insucient, cascade the busbars.
● Busbar dimensions (H x W x D): 76 mm x 465 mm x 70 mm
Procedure
Step 1 Remove the battery terminal covers.
Step 2 Connect the PE cable to the cabinet ground bar.
