7. POPRAVLJANJE
ELEKTROMOTORJE
V
PROTIEKSPLOZIJSKI IZVEDBI SME
POPRAVLJATI SAMO
PROIZVAJALEC
ALI POOBLAŠČENA
DELAVNICA.
OSEBE,
KI RAZSTAVLJAJO ALI
POPRAVLJAJO Ex APARATE, MORAJO
BITI STROKOVNO USPOSOBLJENE IN
IMETI DODATNO ZNANJE S PODROČJA
PROTIEKSPLOZIJSKE ZAŠČITE.
Pri razstavljanju elektromotorja je potrebno paziti,
da ne poškodujemo ploskev, ki tvorijo Ex reže!
Po popravilu elektromotorja morajo tehnične
zahteve elektromotorja ostati v skladu s
certifikatom.
Če se pri popravilu ugotovi, da »nepredirni
okrov« ne ustreza več zahtevam protieksplozijske
zaščite in zahtevam v certifikatu, se mora s tega
elektromotorja odstraniti znak protieksplozijske
zaščite.
