13.3.1
Dismantling
Danger of explosion, fire or danger to life due
to sparking when working in hazardous
areas!
DANGER
Do only work on the motor in non explosible atmosphere and in de-energized
state.
Heed the safety instructions according to DIN EN 50110-1:
1. Disconnect.
2. Protect the system or plant against restart.
3. Determine de-energization.
4. Ground and short-out.
5. Cover or shield any adjacent live parts.
Before starting to work, check with an appropriate measuring device (e.g. an
multimeter) whether parts of the system are still under residual voltage (e.g.
caused by capacitors, etc.). Wait for their discharging time.
Damage to persons and property at installa‐
tion work!
WARNING
●
Do not work on unsecured and operating machines.
●
Before working, secure the machine against accidental movements and
against unauthorized operation.
●
Before dismantling, secure the motor and power supply against falling or
movements before disconnecting the mechanical connections.
Combustions via hot surface with tempera‐
tures over 100 ℃
CAUTION
Let the motor cool down, before maintenance. The thermal time constant sta‐
ted in the technical data is a measure for the cooling time. A cooling time up
to 140 minutes can be necessary!
Use safety gloves.
Do not work on hot surfaces.
In case of malfunctions, maintenance works or dismantling of the motors,
proceed as follows:
1. Use the control commands to bring the drive to a controlled standstill.
2. Switch off the power and control voltage of the drive device.
3. Switch off the main switch of the machine.
4. Secure the machine against accidental movements and against unau‐
thorized operation.
5. Wait for the cooldown times of the motor and the discharge time of the
electrical systems to elapse.
6. Disconnect all electrical connections.
