Before installation or maintenance, the unit must be disconnected from all voltage-sources.
Further it must be ensured that no danger can arise by touching the disconnected voltage-
sources.
Devices which are supplied by AC-voltages must be connected exclusively by switches,
respectively circuit-breakers with the low voltage network. The switch or circuit-breaker must
be placed as near as possible to the device and further indicated as separator.
Incoming as well as outgoing wires and wires for extra low voltages (ELV) must be separated
from dangerous electrical cables (SELV circuits) by using a double resp. increased isolation.
All selected wires and isolations must be conform to the provided voltage- and temperature-
ranges. Further all country- and application-specific standards, which are relevant for structure,
form and quality of the wires, must be ensured. Indications about the permissible wire cross-
sections for wiring are described in the Technical Specifications.
Before first start-up it must be ensured that all connections and wires are firmly seated and
secured in the screw terminals. All (inclusively unused) terminals must be fastened by turning
the relevant screws clockwise up to the stop.
Overvoltages at the connections must be limited to values in accordance to the overvoltage
category II.
For placement, wiring, environmental conditions as well as shielding and
earthing/grounding of the supply lines the general standards of industrial automation
industry and the specific shielding instructions of the manufacturer are valid.
1.4 Cleaning, Maintenance and Service Notes
To clean the front of the unit please use only a slightly damp (not wet!), soft cloth. For the rear

3 Electrical Connections
The terminal screws should be tightened with a slotted screwdriver (blade width 2mm).
3.1 DC Power Supply
The unit accepts DC supply from 18 to 30 V at the terminals 1 and 2. The power consumption
depends on the level of the supply voltage with approx. 100 mA and the additional current
required at the auxiliary voltage output.
All GND terminals are internally interconnected.
3.2 Auxiliary Voltage Output
Terminal 3 and 4 provide an auxiliary output for supply of sensors and encoders.
The output voltage depends on the power supply.
The encoder voltage is approx. 1 V lower than the power supply voltage at terminal 1 and 2
and should be loaded with max. 250 mA.

3.3 Analog Input
The reference potential (AGND) for the analog inputs is connected at terminal 5.
The unit provides two 16 bit analog inputs at terminal 6 and 7. The characteristics of the analog
inputs (voltage input or current input ) can be set in the Menu IN 1/IN 2 PROPERTIES.
Important:
Before connecting the sensor the configuration (voltage or current input) must
be set!
Wiring of the analog inputs:
