For protection against shock hazards as specified in EN 61010, stran-
ded conductors may only be connected using wire end ferrules with
insulating caps. Terminals which are not assigned in the factory must
not be otherwise assigned by the user. We recommend shielding
all encoder connecting leads and earthing the shield at one end.
Earthing at both ends is recommend to avoid RF interference or if
equipotential bonding conductors are installed over long distances.
Sensor connecting leads should not be laid in the same trunking as
the mains power supply cable and output contact leads.

3.1 Connecting the voltage supply

It is possible to switch between two different alternating voltage
ratings by means of the voltage selector switch at the side of the
unit. The higher of the two alternating voltage ratings (48 VAC or
230 VAC) is preset by the factory.
➜ Set the required alternating voltage with the voltage selector
switch.
➜ Connect the supply voltage to connections 2 and 3 in accor-
dance with the terminal diagram.
