Alarm-Relay (X2) - ABB EDS500 Series Manual

Device description
Pin allocation power supply (X1)
1 2 3
Due to the internal overvoltage protection, interrupt any connection to ground of the
device for the time of the measurement before you carry out isolation measurement. This
includes the earthing of the hat rail as well as all shields of all transmission lines and supply
feedings. RJ-12 plugs or RJ-45 plugs can establish earthing via the shield.

Alarm-Relay (X2)

The devices are equiped with a potential free alarm output (relay with isolated switchover
contact). This output corresponds to a device alarm and is activated when the device looses
the power supply or the alarm LED is constantly on (see Chapter 4.8, "Display elements"). The
reason for the signalling of an alarm can be referenced in the system alarm table (EDS500
Manual - Part 2: Alarms and alarm configuration).
