Important notice
In the supply line in the vicinity of the device (easily accessible), a switch
marked as disconnecting device as well as an overcurrent protection element
have to be provided.
Attention!
For the rated control supply voltage, see label at the side of the unit!
WARNING
Hazardous electrical voltage!
Can lead to electric shock and burns.
Before starting work, switch plant and device voltage-free.
Comply with the maximum permissible temperature when installing in a switch cabinet. Ensure
sufficient clearance to other devices or heat sources. If cooling is inhibited, e.g., through close
proximity to devices with increased surface temperature or interference with the cooling-air
current, the permissible ambient temperature is decreased.
Mounting
The device can be mounted:
•
Distribution panel or control panel on 35 mm rail according to EN 60715
Disposal
Disposal should be carried out properly and in an environmentally friendly manner in accordance with legal
provisions.
