 The circuit breakers recommended in the preceding table are for reference only. Customers need to
connect the circuit breakers outside the UPS.
 If multiple loads are connected, specifications for branch circuit breakers must not exceed the
recommended specifications.
 The circuit breaker selection principle is to protect loads and cables, and the cascading principle is to
realize specific protection.
The currents listed in the following table are measured at a rated voltage of 480 V.
