Checking activity designation Optical inspection from outside 1x annually 1x to 2x annually depending on ap plication Inspection of the main contacts Inspection of the auxiliary contacts Every 2 years Extraordinary services need only be carried out if there has been a significant and extraordinary recorded number of switchings under fault conditions If the contactors are being used in particularly dirty environ ments the checking intervals for the optical inspection should be shortened because dirt can impair the insulation clear ances and there is therefore the possibility of a shorter ser vice life or an operational fault e High voltage supply cables or current bars Check of the high voltage supply cables bars and the tightening torques of the fastening screws e Earthing Check of the supply cables and the tightening torques of the fastening screw e Cleaning In case of excessive dirt the surface of the contactors should be cleaned e Inspection of the main contacts Disconnect the main terminals and remove the Upper Module Inspect the main contacts both fixed and movable contacts It requires some experience to evaluate the state of the contacts Even after only a few switchings under load the contacts look used and polluted for the inexperienced eye Contacts need only to be replaced if the wear of the contact tips is more than 70 Replace the Upper Module and secure it Reconnect the main term2.
