instruction and operating manual
4.12 Cable entries
The sealing of cables and conduit entries should be carried out in accordance with National
Standards or the Regulatory Authorities that have certified the actuators. This is particularly
true for units that are certified for use in hazardous areas where the method of sealing must
be to an approved standard, and cable glands, reducers, plugs and adapters must be
approved and separately certified.
Important: • To prevent any water infiltration through the cable conduits,
make sure the cable glands have the minimum protection
degree required by the plant
• If rigid conduits are used, we suggest placing a flexible pipe
connection between the conduit and the terminal board
In order to properly connect the cables, remove the cable entry plugs and make all the
necessary connections.
To guarantee the proper weatherproof and explosionproof fit, screw the cable glands tightly
and block them with a thread sealant. The use of a thread sealant is necessary in case of
explosionproof application.
If some parts of the cable glands have been removed while working on the cable entries, put
them back into place in order to avoid losing the dismantled parts.
Unused entries:
• For explosionproof construction: unused entries must be plugged with metal
explosionproof plugs and blocked with a thread sealant;
• For weatherproof construction: replace the standard plastic protection plugs supplied with
the actuator with metal plugs.
