If you have chosen to order your device with the option of a stainless steel front instead of an aluminum
front, there is a silicone seal on the back of the unit to protect the connection section from moisture.
The silicone seal may become porous after a long operating time. In that case, you should replace the seal
to continue protecting the connection section. You can order the following replacement seals from your
Beckhoff sales department:
