Disassembling

Observe the sequence below, if a servo amplifier has to be disassembled (e.g. for replacement).
1. Electrical disconnection
Switch off the main switch of the switchgear cabinet and the fuses that supply the
system.
Wait at least eight minutes after disconnecting the servo amplifier from the main
supply power before touching potentially live sections of the equipment (e.g.
contacts) or undoing any connections. To be sure, measure the voltage in the DC
Bus link and wait until it has fallen below 40V.
Remove the connectors. Disconnect the earth (ground) connection at last.
2. Check temperature
During operation the heat sink of the servo amplifier may reach temperatures
above 80°C (176°F). Before touching the device, check the temperature and wait
until it has cooled down below 40°C (104°F).
3. Disassembling
Remove the fan housing and disassemble the servo amplifier (reverse of the procedure described
in chapter "Mechanical installation).
