☛
Caution: It is preferable to connect the controller to the mains
transformer supplied.
If the power supply is provided by the customer, the permissible
voltage ranges are to be adhered to.
The voltage supply may be either smoothed direct voltage
(12 V DC +/- 10 %) (any polarity) or alternating voltage
(12 V AC +/- 10 % / 50 - 60 Hz).
