3. SAFETY INSTRUCTIONS
Before starting work disconnect power supply!
All installation and wiring work related to the controller must be carried out only when de-energized.
The appliance should be connected and commissioned by qualified personnel only. Make sure to ad-
here to valid safety regulations, in particular to VDE 0100 (German standard governing power installa-
tions of nominal voltages ≤ 1000 VAC).
The controllers are neither splash- nor drip-proof. Therefore, they must be mounted at a dry place.
Do not interchange the connections of the sensors and the 230V connections under any circumstances! Inter-
changing these connections may result in life endangering electrical hazards or the destruction of the appliance
and the connected sensors and other appliances.
