You should connect the UPS with at least one external battery cabinet to ensure that the
connected critical loads are protected when a power failure occurs. You can connect up to
four units of external battery cabinets to the UPS.

the initial use of the UPS. This guarantees that the UPS can provide sufficient backup
power to the critical loads when a power failure occurs. The charging procedures are as
follows.
(1) Connect the main AC source and the external battery cabinet(s) to the UPS. Please
refer to 5.4 Wiring.
(2) Follow 6. UPS Operation to turn on the UPS and the external battery cabinet(s).
After that, the unit will automatically charge the batteries.
• To connect the external battery cabinet(s) to the UPS, please refer to 5.4 Wiring and
Figure 5-47.
• For the external battery cabinet's grounding information, please refer to Figure 5-20 and
Figure 5-45.
