Overcurrent protection devices must be provided as part of each host equipment rack.
Circuit breakers are located between the AC source and the Sun StorEdge S1 array enclosure.
Circuit breakers must not trip when presented with inrush current of 100 amps lasting 5 ms.
The power can be disconnected for servicing in any of the following ways:
Disconnect the connector from the power module at the rear of the enclosure.
Turn off the circuit breakers in the rack where the enclosure is mounted.
Disconnect the main plug from the AC source.
