WARNING
Risk of crushing and impact
In the event of a power outage, the rotary drives with spring-return mechan-
ism will return suddenly to their initial position. This can result in crushing or
impact injuries if work is being carried out on the rotary drive and its connec-
ted assemblies at this time.
1. Turn off the power to the rotary drive before starting work. Make sure
that nobody is working on the rotary drive or the connected assemblies
(e.g. ventilation flaps) at this time.
2. Only carry out work when the rotary drive spring is not under tension and
is in its initial position.
WARNING
Risk of crushing and impact
If the Allen key is inserted, this can result in crushing and impact injuries if the
rotary drive is started unexpectedly.
1. Turn off the power to the rotary drive before starting work to avoid it be-
ing started unexpectedly.
2. Remove the Allen key immediately after use.
WARNING
Risk of impact
If the drive falls when work is being carried out, it can hit someone and cause
injury.
1. During installation and when dismantling, make sure nobody is located be-
low you.
2. During installation, make sure the rotary drive cannot come loose. The
same applies over longer periods, taking into account external influences
such as vibration, corrosion etc.
