ADVANCE-GRP
5. USE, MAINTENANCE AND REPAIRS
The inspection and maintenance of these interlocked sockets must be carried out by duly trained personnel in accordance
with the highest standards and according to plant-engineering and maintenance rules for environments classified against
the risk of explosion due to the presence of combustible dust (for example: EN 60079-14 or other national regulations/standards).
When carrying out routine maintenance, always check the components responsible for the degree of protection, in particular the
gaskets. Repairs can only be carried out by SCAME.
5.1 PLUGS TO BE USED
Use only ATEX-certified OPTIMA-EX Series plugs suited for installation in Zone 21 with IP66 degree of protection.
5.2 LOCK TO BE USED
For proper locking of the handle in position "0" or "1", use locks with arc Ø of 6.3 mm.
5.3 SOCKET COVER
If the plug is not inserted, the cover of the interlocked socket must remain fully screwed in.
5.4 BUILT-IN PROTECTION DEVICES
In the versions with fuse holder bases, the front opening for control, maintenance and replacement of the fuse must be done with
the system disconnected. If the fuses need to be changed, use the following types of fuses:
- 16A/32A: type CH: 10.3x38mm gG
- 63A: type 22x58mm gG.
5.5 ROUTINE MAINTENANCE
Routine maintenance is necessary in order to guarantee proper operation and preservation of the degree of protection of the
interlocked socket.
1) Check that the gasket is intact every time the enclosure is opened.
2) Check that the closing screws are all in place and well-tightened every time the enclosure is closed.
3) Make sure that the screws/bolts used to fasten the enclosure to the wall are well-tightened and corrosion-free on a yearly
basis.
4) Check the seal of the cable glands on a yearly basis.
5) Check for any damage to the enclosure on a yearly basis.
6) Make sure the screw terminals are tightened as indicated by the manufacturer.
7) In environments with the presence of combustible dust, the surface of the upper wall of the enclosure must be cleaned
periodically, so as to prevent the thickness of the deposited dust from exceeding 5 mm.
5.6 CHEMICAL ATTACK
The interlocked sockets of the ADVANCE-GRP Series are made using:
- Fibreglass-reinforced polyester for the base and for the main enclosure cover;
- Thermoplastic alloy (PC-XILOXANE) for socket cover and ring nut;
- Thermoplastic rubber for base-cover gasket and plate, knob gasket (vulcanized rubber) and LED glass (silicone);
- Thermoplastic rubber (16-32A); Silicone rubber (63A) for socket cover gasket.
The environment where the interlocked sockets will be installed must be considered carefully in order to ascertain the compatibility
of these materials with the presence of chemical agents or corrosive atmospheres.
5.7 DISPOSAL
The product must be disposed of in compliance with national rules on the disposal and recycling of industrial waste.
