Before you start

  • Observe the 5 safety rules before commencing the work: Disconnect. Secure the device against a restart. Check that no voltage is applied. Ground and short-circuit it. Cover or cordon off neighboring live parts.
  • Let the unit cool down sufficiently before you start working on it.
  • Use only genuine spare parts in accordance with the valid spare parts list.
  • Maintenance and replacement as well as retrofitting of an inverter may be performed only by trained specialists. Contact SEW-EURODRIVE Service in case of maintenance work or when retrofitting.

Observe the following points when using functionally safe motor options:

  • Replacing an existing encoder with a safety encoder is not permitted. If necessary, contact SEW‑EURODRIVE Service.
  • Improperly carried out work on drives with functionally safe motor options can result in loss of the safety functions. This can cause injuries and damage.
  • Only qualified specialists are allowed to carry out work on drives with functionally safe motor options.
  • With the EI7C FS built-in encoder, no work may be performed on the encoder. Place an order with SEW-EURODRIVE Service to have any necessary work on the encoder performed.
  • For EK8Z, EK9Z, AK8Z safety encoders, work on the MOVILINK® DDI communication unit is not permitted. Place an order with SEW-EURODRIVE Service to have any necessary work on the encoder performed.
  • When using an encoder mounting adapter to retrofit a safety encoder, the retrofitting of the FS motor option is not identifiable on the motor, e.g. by the FS logo on the motor nameplate. If retrofitting of a safety encoder is performed by the user, the user accepts responsibility and liability. Retrofitting by SEW-EURODRIVE Service is recommended.
