Starting up the battery system should be done in conjunction with the PCE manufacturer’s
recommendations as well as this manual and any local or government safety requirements.
Each battery in the system is powered up separately by turning the double pole breaker to the ON position.
Once powered up, voltage will be present at the DC terminals and the Main Status LED light will glow blue.
