3.5 System power
Main system power
The 4010ES FACU is powered primarily by the ESS. The ESS draws power from the main power line, via an AC block, a transformer and a
rectifier. In the case of main power failure, backup power is provided by backup batteries.
3.5.1 Backup batteries
A pair of 12V sealed lead acid batteries are used as a backup power source in the event of AC failure. The backup batteries are ordered
and shipped separately from the 4010ES system. They are installed at the bottom of the 4010ES back box.
Batteries larger than 33 Ah for a one-bay 4010ES and 50 Ah for a two-bay 4010ES can be used. However, they must be accepted and
installed per UL and local authority requirements using 4100-5128 Battery Distribution Terminal Block. The connection from the battery
box to the 4010ES panel must be within 20 feet and in conduit.
For 50 Ah external batteries with a one-bay box, use box 2081-9282 Remote Battery Cabinet (Red). For 110 Ah external batteries with a
one or two-bay box, use box 2081-9280 Remote Battery Cabinet (Red).
