The controller is supplied with power via a mains
cable. The power supply of the device must be
100 … 240 V~ (50 … 60 Hz).
The mains connection is at the following terminals:
• Neutral conductor N
• Conductor L
• Protective earth conductor
⏚
(common terminal
block)
WARNING!
Electric shock!
L' is a fused contact permanently
carrying voltage.
Î
Always disconnect the de-
vice from power supply be-
fore opening the housing!
