NOTICE |
---|
risk of equipment damage
the battery breaker contact drive J3, J4-1, and J4-2 can
provide a maximum of +24 VDC 250 mA to the undervoltage release coil
or shunt trip release coil. If this value is exceeded, it can damage
the UPS.
Failure to follow these instructions can result in equipment damage.
