WARNUNG
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. Always remove both
power plugs (L and N).
The entire plant must be free of voltage.
1.
