• Where electrical components are being changed, they shall be fit for the purpose and
to the correct specification. At all times the manufacturer's maintenance and service
guidelines shall be followed. If in doubt consult the manufacturer's technical department
for assistance.
• The following checks shall be applied to installations using flammable refrigerants:
• the charge size in accordance with the room size within which the refrigerant contain-
ing parts are installed;
• the ventilation machinery and outlets are operating adequately and are not obstructed
8 . C H ECKS TO E LECT RI CAL DE VICE S
• Repair and maintenance to electrical components shall include initial safety checks and
components inspection procedures. If a fault exists that could compromise safety, then
no electrical supply shall be connected to the circuit until it is satisfactorily dealt with.
If the fault cannot be corrected immediately but it is necessary to continue operation,
an adequate temporary solution shall be used. This shall be reported to the owner of the
equipment so all parties are advised.
• Initial safety checks shall include:
• that capacitors are discharged:this shall be done in a safe manner to avoid possibility
of sparking;
• that there no live electrical components and wiring are exposed while charging,recov-
ering or purging the system;
• that there is continuity of earth bonding.
9 . RE PAI RS TO SEALE D COMP O NE NT S
• 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 absolutely 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 affect-
ed. 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.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detec-
tion equipment. Intrinsically safe components do not have to be isolated prior to working
on them.
10 . RE PAI R TO INT RI NSI CALLY SAF E CO M P ON E NT S
• 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.
