Removing Ex-d modules
1. Disconnect the cordset from the front socket on the module.
2. To release the first catch, position the FB removal tool on the right side of the module. Slide
the FB removal tool towards the backplane up to the stop.

Inserting the FB removal tool
3. Pull out the module a few millimeters together with the FB removal tool until you begin to feel
resistance from the second rear catch.

The first rear catch is released and the module no longer has electrical contact with the
backplane.
Warning!
Explosion hazard due to damaged modules
Forcibly removing modules or using unsuitable tools can damage the module or the backplane,
meaning that explosion protection can no longer be guaranteed.
Only remove modules using the built-in removal device. The built-in removal device forces a
two-stage removal process that contains any potential ignition spark within the pressure-
resistant terminal area.
Danger!
Explosion hazard when removing field connections on the module.
I/O modules with Ex-e front ports require additional measures to be disconnected during
operation.
Do not connect or disconnect the I/O module with Ex-e front connections while the circuit is live
and while it cannot be guaranteed that the surroundings do not present an explosion hazard.
Note!
I/O modules with intrinsically safe front connectors or modules without front connectors (e.g.,
power supply, bus termination module) can be removed while operation is ongoing.
