Remote SMR On/Off

- Function

- Description

- Remote SMR on/off capability exists

through the CSU control.

- CSU automatically shuts down SMR in

case of DC high voltage.

- Users can manually shut down SMR

from CSU for optimizing energy

operation purpose.

Floating/equalize status

- Function

- Description

- SMR floating/equalize status can be set

through the CSU control.

- CSU automatically transfer SMR to

floating mode in case of

(1). Periodical operation (Settable from

CSU)

(2). Mains recover after deep discharge

resulted from blackout/battery test

- Users can manually set SMR to floating

or equalize from CSU.
