BIFFI F01-2000 ELECTRIC ACTUATOR
INSTRUCTION AND OPERATING MANUAL
3�7 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.
Certified cable entries:
- Standard ASA/NPT
(cable entries 2x1”+1x1½”)
- Metric ISO 965
(cable entries 2xM32+1xM40)
Remove the cable entry plugs.
WARNING
Do not damage the mating surface of the cover.
IMPORTANT
In case the screws of the cover must be replaced,
a Stainless Steel AISI 316 must be used with
minimum yield strength of 450
N/mm²
IMPORTANT
- To prevent any water infiltration through the
line 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.
3�6 REMOVING THE ELECTRICAL
ENCLOSURES’ COVERS
Using a 8 mm Allen key, loosen the four screws
and remove the cover.
3�6�1 Terminal board enclosure
To guarantee weatherproof and explosionproof
fit, screw the cable glands tightly (at least
5turns) 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 now 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 plastic standard protection plugs
supplied with the actuator with metal plugs.
