In case the screws of the cover must be replaced,
a SS AISI 316 must be used with minimum yield

3.5 electrical connections
Before powering the actuator check that the
supply voltage details on the nameplate are
correct for the plant� Access to terminals for
electrical connections and commissioning is
through the terminal cover, since all settings
are non-intrusive� The removal of any other
covers without Biffi’s approval will invalidate
the warranty�
Biffi will not accept any responsibility for any
damage or deterioration that may be caused�

All the accessories (in particular cable glands)
must be certified.
As of 30 June 2003, the above accessories
must carry the CE certification conforming with
94/9/CE Directive.
3.5.1 plants requirements
Protection devices (overcurrent breakers,
magneto-thermal switches or fuses) should
be provided on the plant at Customer care,
to protect the mains line in case of motor
overcurrent or loss of insulation between
phases and earth�

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 Rc ISO7/1
(cable entries 2x1”+1x1½”+ (optional) 1x¾”
+ (optional) 1x1¾”)
- Standard ASA/NPT
(cable entries 2x1”+1x1½”+ (optional) 1x¾"
+ (optional) 1x1¾")
- Metric BS 3643
(cable entries 2xM32+1xM40)
- Pg DIN 40430
(cable entries 1xPg29)
Remove the cable entry plugs�

- The cable reducers are certified according to
the actuator certification.
- Refer to the actuator drawing.

- 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.
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 and weatherproof 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�
