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.
CAUTION
Impact and tripping hazard
If the rotary drive is not positioned carefully, it can pose an impact and trip-
ping hazard.
1. As far as possible, please avoid installing the rotary drive near to where
people will be walking or working.
2. Position the rotary drive to avoid any risk of tripping or head impact.
3. If necessary, provide warning indicators or padding around any potential
impact points.
The actuators do not need maintenance in terms of function. Relevant regional maintenance
regulations must be complied with in accordance with legal requirements or factory stand-
ards.
Drive units are maintenance-free. An annual inspection is recommended. The applicable
standards can be consulted for inspecting and servicing electrical systems. Ex devices should
only be opened by the manufacturer.
All applicable national and international standards and regulations for Ex areas must be ob-
served. Certified equipment must be installed in accordance with the manufacturer’s instruc-
tions. If you use the device in a manner that contravenes that stipulated by the manufac-
turer, this can impair the safety level of the device. The applicable standards can be consul-
ted for project planning, selection and setting up electrical systems. An Ex e terminal box
(e.g. ExBox-...) must be used for the electrical connection.
Routine inspections of fire dampers
For periodic inspections, it is important to make sure this takes place with the voltage discon-
nected (cut off the power supply to the drive). The test button on the ExPro-TT- ... is only for
on-site checks on the drive function.
