Closing the cover of the support beam
IMPORTANT!
For safe operation, the support beam, the cover and the service door
must be earthed. The service door and the cover are earthed via
protective conductors, an earthing point on the cover and an earthing
point on the support beam.
When the mounting work is completed or if the work is interrupted
for a longer period of time, the support beam must be closed with the
cover. We recommend checking that the protective earth conductors
for the cover and the service door are correctly connected when
closing the cover.
