4.2.2 Intelligent battery charger:
The Intelligent battery charger indicated here is to convert the auxiliary power supply from connected
from External PT or equivalent to suitable form required by components like Battery, RER615, ACM and
external communication modem. This Battery charger is temperature compensated.
4.2.3 Auxiliary supply
The LV control cabinet requires auxiliary power to operate the Recloser, Actuator control Module (ACM),
HV & LV cubicle heating, illumination, etc. A separate outdoor type 2 x1.5 Sq.mm jacketed cable is

external auxiliary power source
.
4.2.4 Actuator Control Module
The Actuator Control Module (ACM) module gets its power supply from
Intelligent battery charger.
ACM regulates the closing and tripping signals to magnetic actuator as per the
feedback from HV unit and interaction with relay by charging/discharging the
capacitors.
ACM is hardwired to RER615 relay to perform operations.
