Handleiding

9. Repairs to sealed components:

• During repairs to sealed components, all electrical supplies shall be disconnected

from the equipment being worked upon prior to any removal of sealed covers, etc.

If it is necessary to have an electrical supply to equipment during servicing, then a

permanently operating form of leak detection shall be located at the most critical

point to warn of a potentially hazardous situation.

• Particular attention shall be paid to the following to ensure that by working on

electrical components, the casing is not altered in such a way that the level of

protection is affected. This shall include damage to cables, excessive number of

connections, terminals not made to original specification, damage to seals,

incorrect fitting of glands, etc. Ensure that apparatus is mounted securely. Ensure

that seals or sealing materials have not degraded such that they no longer serve

the purpose of preventing the ingress of flammable atmospheres. Replacement

parts shall be in accordance with the manufacturer's specifications.

10. Repair to intrinsically safe components:

Do not apply any permanent inductive or capacitance loads to the circuit without

ensuring that this will not exceed the permissible voltage and current permitted for the

equipment in use. Intrinsically safe components are the only types that can be worked

on while live in the presence of a flammable atmosphere. The test apparatus shall be

at the correct rating. Replace components only with parts specified by the

manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere

from a leak.

11. Cabling:

Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration,

sharp edges or any other adverse environmental effects. The check shall also consider

the effects of aging or continual vibration from sources such as compressors or fans.

12. Detection of flammable refrigerants:

Under no circumstances shall potentially sources of ignition be used in the searching

for or detection of refrigerant leaks. A halide torch (or any other detector using a naked

flame) shall not be used.

Note: The use of silicon sealant may inhibit the effectiveness of some types of leak

detection equipment. Intrinsically safe components do not have to be isolated prior to

working on them.
