Removing a Module
To remove the module, proceed as follows:
1.
In the Case of Redundancy: The IM 153 -2 / -2 FO that is to be replaced must always be
deactivated!
Switch off the assigned power supply module or disconnect it on the IM 153 -2 / -2 FO.
WARNING
If in redundant mode, the two IM 153-2 are connected to a power supply module, then
when disconnecting the 24 V supply of an IM 153-2, this could bring about a short circuit
of the non-insulated (loose) cable ends.
In the event of a short circuit of the power supply, the second IM 153-2 and with that its
ET 200M always fails completely.
Therefore, when disconnecting the supply voltage, always work extremely carefully and
insulate the two cable ends until you connect to the new IM 153-2.
No redundancy: Switch the on / off switch of the power supply module to position 0 ( :
output voltages 0 V).
2.
Remove the bus connector or the FOC.
In the case of fiber-optic cables: Fold out the handle for the plug adapter and with that
remove the plug adapter from the IM 153-2 FO.
3.
Disconnect the wiring.
4.
Loosen the fixing screws of the IM 153 -2 / -2 FO.
5.
Swing out the IM 153 -2 / -2 FO.
Installing a New Module
Install the new module as follows:
1.
On the IM 153 -2 / -2 FO, set the same DP address as you had on the old IM 153 -2 / -2
FO.
2.
Insert the new IM 153 -2 / -2 FO and swing it down.
3.
Screw the module on securely.
4.
Wire the IM 153 -2 / -2 FO.
5.
Screw the bus connector firmly into place.
6.
Put the standby switch of the power supply module into the 1 position (output voltages to
rated value).
Response of the ET 200M After Module Replacement
If there is a fault after replacing the module, with
STEP 5 or STEP 7 in the diagnostics buffer
you can view the cause of error.
