Start by fitting the rear base of the gateway to the
upper part of the rail, pushing downwards (1) to
compress the gateway’s spring. Then push the
gateway against the DIN rail (2) until the base of the
gateway box fits onto the rail.
Start by pushing the gateway downwards (1) to
compress the gateway’s spring. Then pull the
bottom of the gateway box forwards (2) until the box
comes away from the rail.
N.B. The spring is also used to earth the gateway (Protective Earth).

2.4. Powering the gateway

DeviceNet / Modbus RTU gateway – View from underneath
–+
Power supply
24V isolated (±10%)
95 mA max.
We do not recommend powering the gateway using the 24V power voltage on the
DeviceNet network. It is better to use a separate power supply, because the gateway needs to
be powered using a stabilised voltage, which is not necessarily the case with the power
voltage on the DeviceNet network.
N.B. The negative 24V power supply terminal should be connected to the installation’s
earth.
