4.2.7. XP31 - RJ-45 Ethernet interface for synchronization with external signal
This Interface is used to communicate with an external synchronization device, such as MBSM.
It can be used to synchronize the outputs of multiple UPS devices, even when they do not supply a
common output. This enables an external static switching device (e.g. CROSS) to commutate between
UPS outputs in the event of a malfunction, without creating synchronization problems.
The Interface is SELV-isolated from UPS primary circuits.
Warning
This interface and its function are for authorized Vertiv service technicians, only. Do
not remove any connected cable from this interface or connect any cable to it.
