5.2.3 Closing the housing covers
NOTICE
Devices with EPDM cover seal - leaking transmitter!
Mineral-, animal- or plant-based lubricants cause the EPDM cover seal to swell and the
transmitter to leak as a result.
‣
It is not necessary to grease the thread due to the coating applied to the thread at the
factory.
NOTICE
The housing cover can no longer be closed.
Damaged thread!
‣
When closing the housing covers make sure that the threads on the covers and the housing
are free from dirt, such as sand. If you encounter resistance when closing the covers, then
check the threads again for dirt.

The covers for the terminal compartment and electronics compartment are hooked into the
housing and closed with a screw in each case. These screws must be tightened finger-tight (2
Nm (1.48 lbf ft)) to the stop to ensure that the covers are securely seated and leak-tight.
