9. Instructions for the explosionproof enclosures

Important: Electric actuator ICON2000 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

(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 film of recommended grease (see Sect. 618/1 chapt. D).

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

(as stated below), or of a better quality.

Cover Local Interface Covers

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).

10. Installation in environment with explosive dusts

Important: Electric actuator ICON2000 shall be installed and maintained

according to the applicable rules regarding the electrical

installations in hazardous area (other than mines) classified

as zone 21 (dust); example: EN 50281-1-2 (dust) and/or other

national standards).

Please make sure that:

• the joint surfaces are greased with silicon oil or equivalent before assembly

• the cable glands have minimum protection degree IP6X (EN 60529)

• periodically verify the quantity of dust deposited on the enclosure and clean it

if more than 5mm.
