Replacing a defective electronic module
You have already uninstalled the electronic module:
1. Remove the removable part of the coding element from the new electronic module. The
coding element is located on the underside of the electronic module.
2. Install the new electronic module (same type) on the terminal module, checking for an
audible latching sound.
3. Follow steps 4 to 7, see Installing and labeling electronic modules2 DO Relay UC60V/2A.
Note
Check the coding element before you install the new interface or electronic module.
6.5.5 Pulling and plugging optical transceivers
Compatibility of the optical transceivers
The IM 152-1PN interface module has SFP sockets for two optical transceivers. Only one type of
optical transceiver is supported. Only this type of optical transceiver is approved for use in
hazardous areas.
If the interface module detects another optical transceiver, a diagnostic interrupt is triggered.
WARNING
Danger of explosion with wrong transceiver
The IM 152-1PN only works with intrinsically safe SFP transceiver A5E51793919. Plugging in
other transceivers may cause explosions.
Do not plug another transceiver into the IM 152-1PN.
The optical transceivers can also be removed and replaced during operation, even in the
hazardous area.
