4.1.1.1

WIRING WITH EXTERNAL BATTERY MODULE (EBM) (DC SOURCE TO UPS)

Parallel UPS connection with ‘independent batery’

In the parallel system, independent EBM connect to each UPS. Please refer to chapter 3.4.3

Parallel UPS connection with ‘common battery’

In the parallel system, you can also set up ‘common battery’(user’s own battery) for all UPSs. Please refer to below
diagram for battery wiring.

Note:

Common battery configuration is not suitable for standard model.

WIRING FOR PARALLEL SIGNAL CABLE
Parallel system ‘parallel cable’ diagram:

Connect each UPS one by one with ‘parallel cable’, make sure the
cable is

screwed to parallel port tightly.

It is recommended to lock the ‘parallel cable’ (as above) for
preventing the parallel ports suffering an unexpected pulling-force
and causing the parallel system fault.
