About communication interfaces

This section describes the communication features of the Eaton 91PS/93PS
UPS.

CAUTION

All the communication interfaces are SELV circuits. When connecting to
other equipment, make sure that you maintain this characteristic.

The UPS has the following communication interfaces:

MiniSlot 1

MiniSlot 2

USB device (connection to computer)

Communication cable conduit

Emergency Power Off (EPO)

Relay output

USB host (connection to accessories)

Signal inputs

RS-232 port for service
