10.3 Replacing an I/O Module
Explosion Risk - Prior to starting work, ensure that there is not a
potentially explosive atmosphere.
Dangerous contact voltage - Prior to removing modules, the RSTi-EP
station must be completely de-energised (supply of the field bus
network adapter and all external feed-in). Ensure that the place of
installation (switch cabinet and so forth) has been disconnected from
the power supply.
The components in the RSTi-EP series can be destroyed by electrostatic
discharge. Ensure that personnel and work equipment are adequately
grounded.
To remove an individual module from the station, all modules to the right of it and the termination kit
must be moved by approximately 5 cm (2 in).
➢ To replace an I/O module
1. Unfasten the mounting screw on the right-hand end bracket.
2. Slide the end bracket and end plate approximately 5 cm (2 in) to the right or remove both
parts from the DIN rail.
3. Open the release lever on the module furthest to the right.
