Section 3: Installation
3.9 Instructions for the Explosionproof Enclosures
NOTICE
Electric actuator F01-2000 shall be installed and maintained according to the applicable
rules regarding the electrical installations in hazardous area (other than mines) classied
as zone 1 (gas); example: EN 60079-10 (hazardous area classication), EN 60079-14
(electrical installation), EN 60079-17 (maintenance), and/or other national standards.
During the dismantling and subsequent reassembling of the explosionproof enclosures
(covers, cable glands, joints), be careful to bring these enclosures back to their original
condition to maintain their integrity. In particular, be sure the joint surfaces of all
enclosures are spread with a lm of recommended grease (see Section 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 lm 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.
!
WARNING
Do not operate the actuator electrically when the electrical enclosures are removed.
Operating the unit with the electrical enclosures removed could cause personal injury.
• Replace the weatherproof seals that may have been removed (O-ring for the
covers, O-ring for the explosionproof joint of the motor).
When the Ex d e version is supplied, according to the protection degree shown on the
nameplate, waterproof cable glands with a minimum IP68 protection degree, can be used.
