Electrical installation

3.4.1 Cable/conduit entries
The electronics housing has two ½ - 14 NPT entries (optional: adapters for two M20×1.5).
Minifast and Eurofast adapters are also available. The connections are made in accordance
with local or plant electrical codes.
Make sure that unused ports are properly sealed to prevent moisture or other
contamination from entering the electronics housing.
Note
Use enclosed metal plug to seal the unused entry/entries. The plastic plugs mounted at
delivery are not sufficient as seal!
Note
Thread sealing (PTFE) tape or paste on male threads of conduit is required to provide a
water/dust tight conduit seal and to meet the required degree of ingress protection as
well as to enable future removal of the plug/gland.
3.4.2 Grounding
The housing should always be grounded in accordance with national and local electrical
codes. Failure to do so may impair the protection provided by the equipment. The most
effective grounding method is direct connection to earth ground with minimal
impedance.
There is an external grounding screw located at the bottom of the housing and an internal
grounding screw located inside the housing, see
The internal ground screw is identified by a ground symbol:
