Exiting Manual Override
Because of the criticality of an event that may lead to a manual override, care has been taken to ensure
that the system does not randomly come out of this state, unless explicitly forced to exit. The manual
override state is immune to power cycles, resets, reset glitches, etc. A service visit to the site might be
needed perform the exit from manual override.
To exit manual override on site, perform the following steps:
1. OPEN the following breakers in sequence:
a. Encharge breaker inside Enpower
b. Mains breaker powering the Enpower from the grid side (this could be inside or outside the
Enpower unit)
c. Auto transformer breaker inside Enpower
NOTE: No need to open PV combiner breaker and load side breaker inside Enpower.
2. Turn OFF all Encharge units by turning OFF their DC switches.
3. Wait for at least 60 seconds for all residual charge on the control boards to get discharged.
4. Turn the manual override toggle inside the Enpower to the right to manually OPEN the MID relay.
5. CLOSE all the breakers in sequence:
a. NFT breaker inside the Enpower
b. Mains breaker
c. Encharge breaker inside the Enpower
6. Turn ON all Encharge units by turning ON the DC switches.
NOTE: If Load Side breaker or PV combiner breakers were OPEN inside Enpower, they
can be CLOSED now.
The Enpower system is now no longer in manual override state and is fully functional.
