3.1 Voltage supply connection
AC voltage connection 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.
➜ Connect the alternating voltage supply to terminals 2 and 3 in
accordance with the terminal diagram.
Voltage supply external fusing
24 V ±10 % 50/60 Hz T 400 mA
48 V ±10 % 50/60 Hz T 200 mA
115 V ±10 % 50/60 Hz T 100 mA
230 V ±10 % 50/60 Hz T 50 mA
DC voltage connection Connect an interference-free voltage supply, i.e. do not use it for the
parallel connection of drive systems, contactors, solenoid valves, etc.
➜ Connect the DC voltage according to the terminal diagram.
Voltage supply Recommended external fuse
24 VDC ±10 %, max. 5 % RW T 400 mA
Fire protection: Operate instrument on the MAINS with external fuse
recommended on the rating plate. In case of disturbance, make sure
that 8 A /150 VA (W) are never exceeded - as defined per EN 61010.
3.2 Assignment of relay contacts (option)

Contact P2
4 3
Contact P1 The signal outputs (contacts 3 to 6) are floating relay contacts. The
signal outputs can be assigned as per the adjacent terminal dia-
gram. The type of outputs, as momentary or latched signal, can be
chosen in the programming lines 35 / 36. Their function, as normally
open or closed, is selected in programming line 33.

The user must take care that, in case of disturbance, the contact
rating of 8 A / 150 VA (W) is not exceeded. The output relay of the
instrument (1 relay or more) may, in total, switch max. 5 x per
minute. Admissible clicks as per interference suppression
standards EN 61000-6-4 for the industrial sector. In case of higher
switching rate, the user is responsible for and in charge of providing
interference protection on site in consideration of the load to be
switched.
