7. MAINTENANCE
The maintenance schedule depends on use and operating conditions but, generally, it should not exceed three months.
The maintenance operations have to be made by specialised personnel, in compliance with safety rules.
At our offices, you can find the “Routine and extraordinary maintenance forms”.
WARNING : If you detect a problem and you can not take immediate action to solve it, please make sure the
charger is identified as not working and " NOT to be used " .
7.1
Preliminary recommendations
• Before performing maintenance or repairs make sure the power plug and the battery are both disconnected.
• Carefully clean all parts: the charger , the battery, the cables, all the plugs etc.
• If the power cord or battery cables show signs of wear and are also partially damaged, please have them replaced
immediately by qualified personnel .
• At our offices you can find available dedicated special " modules for routine and extraordinary maintenance"
7.2
Put the equipment out of service
When you want to do a routine or extraordinary maintenance on your Battery Charger, or you do not want to use it for a
long time or there is a fault, you must keep it out of service.
Please follow these instructions:
•
If the charger is in function switch it off.
•
Rotate the AC mains switch in “off” position and disconnect the plug.
•
Disconnect the battery plug.
Should you wish not to use your Battery Charger for a time, please do not expose it to heat or atmospheric agents, but
keep it in a dry, safe place. The AC main plug and the battery plug must be raised from the ground and secured.
7.3 Routine Maintenance
Perform maintenance every 3 months or any time it is necessary.
•
Clean carefully the AC and battery cables. Check they are not damaged or burnt. In this case, replace them
immediately.
•
Check the AC mains and battery plugs. If they are crushed or burnt or damaged, replace them immediately.
•
Electrical equipment must not be exposed to dust and humidity. Clean the Battery Charger. Should it be too dirty or
damp, put it in a safer place. The same is valid for the battery.
7.4 Extraordinary Maintenance
Perform maintenance every year or when a problem occurs ( i.e. burning fuse ) or you notice a fault .
•
Follow the checklist of “Routine maintenance”.
•
Open the Battery Charger. Clean carefully the dust on each component: the printed circuits by a clean brush, on the
other components by a blow of compressed air; stay at 20 cm (8 inch) at least.
•
Check the screws and electrical connections are well tightened. The use of a thermal imaging camera is an excellent
way to understand if there are loose connections or weak points where you must intervene . The charger should be
on for at least 10 minutes before you make measurements
•
Check the fuses, the fuse holders and the moving mechanical parts (contactor).
•
Request in advance replacement parts that are not available at your site.
