Cable Entry; Routine Maintenance - Scame Rocker-Ex Serie Installation, Utilisation Et Entretien

3.4 CABLE ENTRY

Certified cable-glands and blanking plug elements can only be fitted with a suitable service temperature
range and IP rating commensurate with IP rating of the enclosure. Only Ex e certified cable entries and
blanking plugs are permitted for use.
The mounting directives applicable to the cable entries and or blanking plugs used shall be observed.
Unused holes shall be closed with a certified blanking plug.
Care has to be taken that when fitting the cable entries, sealing inserts appropriate to the cable diameter
are used. In order to ensure the required minimum protection category, the cable glands are to be
tightened down. Overtightening might impair the protection.
Note: have to Use the gasket of the cable gland in order to guarantee the degree of protection IP66.
4. SERVICING AND MAINTENANCE AND REPAIRING
To check as part of the maintenance schedule:
- The conductors must be carefully connected
- The conductor insulation must reach to the terminal. The conductor itself must not be damaged
(nicked) when removing the insulation.
- Ensure that the maximum permissible conductor temperatures are not exceed by suitable selection
of cables and means running them.
- Clean periodically in order to avoid ≤ 5mm of dust layer.
Inspection and maintenance of this equipment shall be carried out by suitably trained personnel in
accordance with the applicable code of practice (e.g. IEC/EN 60079-17). During servicing, it is
particularly important to check those components upon which the type of protection depends.
Each ROCKER-EX[GD] light switch shall be subject to a routine dielectric streght test of 1000 V + 2U
rms or 1500 V rms, whichever is the greater applied for a period of 60 s as required by clause 6.1
of IEC/EN 60079-7. Alternatively, a test shall be carried out at 1.2 times the test voltage, but maintained
for at least 100 ms.

4.1 ROUTINE MAINTENANCE

Routine maintenance is required in order to guarantee the efficiency of the switch and to maintain the
required level of protection.
1) Check that the mounting screws/bolts are tight and free of corrosion
2) Check the enclosure for damage
3) Check the gasket of the enclosure that is not damage
4.2 RESISTANCE TO CHEMICAL AGENT
Consideration should be given to the environment in which these enclosures are to be used to determine
the suitability of these materials to withstand any corrosive agents that may be present.
4.3 DISPOSAL
Disposal and recycling of the product shall be done according to national regulations for waste disposal
and recycling.
