The connection cables are inserted into the terminal box via an exchangeable cable entry plate
or cable entry support . The cable entry plate is drilled by default. The cable glands are not
included in the standard scope of supply.
For the explosion-proof version, the cable entry plate is not drilled by default. This enables you
to adapt the number and size of the boreholes to the rated conditions.
The cable entry can be turned by 180°.
