WARNING

Do not use unconnected terminals such as terminal 9 as support point terminal�

6.2 Voltage supply (power)

► Voltage supply see type label�

► The device may only be operated using one of the possible voltage

connections, i�e� either terminals 7/8 (AC) or terminals 1/2 (24 V DC)�

► All supply and signal cables must be laid separately� Use a screened cable if

required in the application�

6.2.1 AC supply

► The AC supply cable must be protected according to the cross-section used

(max� 16 A)�

If the unit is supplied on AC, the low voltage provided for the sensor supply meets

the SELV criteria according to EN 61010, overvoltage category II, soiling degree 2�
