Removing The Terminal Module (From The Right) - Siemens ET 200S Manual

Removing the Terminal Module
The terminal module is wired, and there are other terminal modules on the right
and left.
A terminal module in the ET 200S distributed I/O system can only be removed
when there is a clearance of around 8 mm to the adjacent terminal modules (you
achieve this clearance by moving the adjacent modules).
1. Switch off the supply voltage on the terminal module and, if applicable, the
power module.
2. Disconnect the wiring on the terminal module.
3. Removal from the right: Use a screwdriver to push the locking mechanism on
the previous terminal module/interface module (on the left) down until the
mechanism stops, and move the terminal module to the right.
Removal from the left: Use a screwdriver to push the locking mechanism on the
terminal module down until the mechanism stops, and move the terminal
module to the left.
Note: The locking mechanism is under the terminal module.
4. With the locking mechanism depressed, tip the terminal module so that it
comes off the rail.
