3�9 INSTRUCTIONS FOR THE
EXPLOSIONPROOF ENCLOSURES
IMPORTANT
Electric actuator F01-2000 shall be installed
and maintained according to the applicable
rules regarding the electrical installations in
hazardous area (other than mines) classified
as zone 1 (gas); example: EN 60079-10
(hazardousareaclassification), EN 60079-14
(electrical installation), EN 60079-17
(maintenance), and/or other national standards.
During the dismantling and subsequent
reassembling of the explosionproof enclosures

IMPORTANT
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 occur as a result of cover
removal.
Allterminations should be made by insulated
ring or spade connectors using the appropriate
crimping tool. This operation will ensure easy
and correct electrical connection.
Connect the motor supply cable previously
sized in accordance with:
- The absorbed current correspondent to the
actuator nominal torque with the torque
limiting device set at 100 percent (see the test
certificate attached to the actuator).
- The applicable plant and safety norms.
Assemble the power terminals protective
barrier, located in the terminal board
compartment, using the enclosed screws.
The control circuit (controls and signals) must
be connected by means of a multicore cable
to the corresponding numbered terminals
according to the wiring diagram.
The internal cables of the actuator are also
numbered according to the wiring diagram.
Actuators are always delivered with the
motors wound and connected in accordance
to customer requests. Voltage and frequency
values are stated on the motor nameplate.

to maintain their integrity. In particular, be
sure the joint surfaces of all enclosures are
spread with a film of recommended grease
(seechapter4, Lubrication).
So please:
• Do not damage the explosionproof mating
surfaces on the housing and on the electrical
enclosures covers.
• Reinstall all the screws that go with the
dismantled parts, and block them with a
thread sealant after spreading them with
a film of copper- or molybdenum-based
grease. This will keep screws from sticking
and make maintenance operations easier.
• Check that the bolts and screws are the
same dimension and quality as the original
ones (see bolting table below), or of a
betterquality.
