WARNING
The device shall be powered off while accessing any of the connectors X1 (power
connector) or X4 (alarm relay). Any other connectors (e.g. RS-232 or 4-wire/2-wire
communication port/X3) are hot-pluggable while the device is operating.
WARNING
No plug shall be freely accessible in normal operation due to safety reasons.
ADVICE
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 measurements. 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 also establish earthing via the shield.

Serial interface to DTE (X2)
The RJ-45 connector X2 forms an RS-232-D interface. If the modem is connected to an RTU, an
adapter cable has to be used which connects the pin pairs.
