Preliminary work regarding inspection and maintenance

Carry out the following steps before all inspection and maintenance work:

  1. WARNING! Electric shock caused by dangerous voltages in the connection box. Severe or fatal injuries. De-energize the device. Pay attention to the 5 safety rules in chapter "Carrying out electrical work safely". Afterwards, wait 5 minutes.
  2. WARNING! Risk of burns due to hot surfaces. Severe injuries. Let the device cool sufficiently before touching it.
  3. Secure the output shaft of permanently excited motors against rotation. You thereby avoid an electric shock from the regenerative operation during the rotation of the shaft.
