ELECTRONIC CIRCUIT BREAKER (ECB)
The ECB is activated under the following conditions:
1.
battery voltage drops below the Vdisco (1.66V/cell)
2.
battery overcurrent or overload (refer to page 3)
The ECB will latch open only when there is no mains input present. It will reset when mains power is restore or can be
manually reset by following the procedure in step 6 on page 8 of this manual.
