4.2.9. Protective Plug
A protective plug is provided for the connection of the fibre-optic cables. If the optical
connection is done without this kit, the RU no longer has the stated IP class. Dust,
humidity or water might ingress into the housing and damage the RU.

Note:
Only high-quality connectors must be used for this type of plug. Qualified
brands are Diamond or Huber & Suhner.
For plug assembly, observe the following instruction:
1. Pass one or two contacts through the
backshell and the clamp ring.
2. Place the contact(s) on the lower insulation body by pushing the groove of the
contact into the cavity. If there is only one contact, cavity A
must
be used. *
3. Then, mount the upper insulation body on the lower insulation body. **
4. Bring the insulator into the plug. The narrow groove of the insulator must be fitted
into the stamp of the plug.
*
To release the contact for disassembling, push the inner snap to the side and pull the contact out.
** To release upper and lower insulation bodies for disassembly, use a small screwdriver to carefully
open the snap-connections at the left and right side of the insulator without damaging them.
