2.2.7 Maintenance and Cleaning
The servo amplifier does not require maintenance. Opening the servo amplifier voids the war-
ranty.
The inside of the unit can only be cleaned by the manufacturer. To clean the device exterior:
Casing: Clean with Isopropanol or similar cleaning solution.
Protective grill on fan: Clean with a dry brush.
Do not immerse or spray the servo amplifier.
2.2.8 Disassembling
Observe the sequence below, if a servo amplifier has to be disassembled (e.g. for replace-
ment).
1. Switch off the main switch of the switchgear cabinet and the fuses that supply the sys-
tem.
WARNING
Contacts can still have dangerous voltages present up to 10 minutes
after switching off mains voltage. Risk of electric shock! Wait at least 10
minutes after disconnecting the servo amplifier from the main supply
power before touching potentially live sections of the equipment (e.g. con-
tacts) or undoing any connections. To be sure, measure the voltage in the
DC Bus link and wait until it has fallen below 60V.
2. Remove the connectors. Disconnect the potential earth connection last.
3. Check temperature.
CAUTION
During operation, the heat sink of the servo amplifier may reach tem-
peratures above 80 °C (176 °F). Risk of minor burns. Before touching the
device, check the temperature and wait until it has cooled below 40 °C
(104 °F).
4. Disassembling. Disassemble the servo amplifier (reverse of the procedure described in
chapter "Mechanical installation).
2.2.9 Repair and Disposal
Only the manufacturer can repair the servo amplifier. Opening the device voids the warranty.
Uninstall the servo amplifier as described above, then send the servo amplifier in the original
packaging to the manufacturer.
In accordance with the WEEE-2002/96/EC-Guidelines and similar, the manufacturer
accepts returns of old devices and accessories for professional disposal. Transport costs
are the responsibility of the sender.
