the refrgerant contanng parts are nstalled; the
ventlaton machnery and outlets are operatng
adequately and are not obstructed; f an ndrect
refrgeratng crcut s beng used, the secondary
crcut shall be checked for the presence of
refrgerant; markng to the equpment contnues
to be vsble and legble. Markngs and sgns that
are llegble shall be corrected; refrgeraton
ppe or components are nstalled n a poston
where they are unlkely to be exposed to any
substance whch may corrode refrgerant
contanng components, unless the components
are constructed of materals whch are nherently
resstant to beng corroded or are sutably
protected aganst beng so corroded.
2.1.9 Checks to electrcal devces
Repar and mantenance to electrcal components
shall nclude ntal safety checks and component
nspecton procedures. If a fault exsts that could
compromse safety, then no electrcal supply shall
be connected to the crcut untl t s satsfactorly
dealt wth. If the fault cannot be corrected
mmedately but t s necessary to contnue
operaton, an adequate temporary soluton shall
be used. Ths shall be reported to the owner of
the equpment so all partes are advsed.
Intal safety checks shall nclude: that capactors
are dscharged: ths shall be done n a safe manner
to avod possblty of sparkng; that there no lve
electrcal components and wrng are exposed
whle chargng, recoverng or purgng the system;
that there s contnuty of earth bondng.
2.2 Repars to sealed components
2.2.1 Durng repars to sealed components,
all electrcal supples shall be
dsconnected from the equpment
beng worked upon pror to any removal
of sealed covers, etc. If t s absolutely
necessary to have an electrcal supply
to equpment durng servcng, then
a permanently operatng form of leak
detecton shall be located at the most
crtcal pont to warn of a potentally
hazardous stuaton.
2.2.2 Partcular attenton shall be pad to the
followng to ensure that by workng
on electrcal components, the casng s
not altered n such a way that the level
of protecton s affected. Ths shall
nclude damage to cables, excessve
number of connectons, termnals
not made to orgnal specfcaton,
damage to seals, ncorrect fttng of
glands, etc. Ensure that apparatus s
mounted securely. Ensure that seals
or sealng materals have not degraded
such that they no longer serve the
purpose of preventng the ngress of
flammable atmospheres. Replacement
parts shall be n accordance wth the
manufacturer’s specfcatons.

Note:
The use of slcon sealant
may nhbt the effectveness
of some types of leak detecton
equpment. Intrnscally safe
components do not have to be
solated pror to workng on
them.
2.3 Repar to ntrınsıcally safe
components
Do not apply any permanent nductve or
capactance loads to the crcut wthout ensurng
