1.5 Installing the device
The device is intended for top-hat rail installation and is suitable for operation in fuse boxes and dis-
tribution cabinets. The device can be positioned immediately adjacent to another device without gaps.
WARNING DANGER TO LIFE FROM ELECTRIC SHOCK AND/OR FIRE!
• Switch off the power to the entire plant before installing. Otherwise, mains voltage and/or exter-
nal voltage may still be present, even if the control voltage is switched off!
• Observe the maximum loads for all connections!
The entire plant must be free of voltage.
1. (A) Place the device with the leading edge at an acute angle to the top-hat rail.
2. (B) Push the device downwards onto the top-hat rail.
The device snaps into place with the fastening safety catch (a) on the top-hat rail.
You can now connect the device.
