Preliminary work regarding inspection and maintenance

WARNING

Risk of injury if the drive starts up unintentionally.
Severe or fatal injuries.
  • Before starting work, de-energize the drive via a suitable external disconnection device.
  • Secure the drive against unintended re-connection of the voltage supply.
  • Secure the output shaft against rotation.

WARNING

Risk of burns due to hot surfaces of the unit (e.g. the heat sink).
Severe injury.
  • Do not touch the unit until it has cooled down sufficiently.

NOTICE

Damage to the drive.
Possible damage to property.
  • Note that only SEW‑EURODRIVE Service or specialists trained by SEW‑EURODRIVE are allowed to carry out motor and/or brake maintenance.

Perform the following steps before any inspection or maintenance work:

  1. Disconnect the device from the power supply with suitable external measures before you start working on the device and secure it against unintentional reconnection to the voltage supply.
  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.
