13.2.1. Power supply IP54
The 4-pole circular plug-in connector for the power supply is configured as follows:
Electronics Inputs
Valves /
Outputs
24 V DC (1)
valves /

24 V DC (2)
logic
GND (3)

GND (4)
valves /

Pin 1: +24 V - valves (outputs)
Pin 2: +24 V - logic + inputs
Pin 3: GND - logic + inputs
Pin 4: GND - valves (outputs)
Figure 43: Power supply configuration
Pin 1 of the power supply must be supplied with a 4 A medium time-lag fuse; Pin 2 with 1 A.
NOTE!
To ensure electromagnetic compatibility (EMC) connect the screw terminal FE (functional earth) to earth
potential using a short cable (30 cm).
13.2.2. IP54 field bus connection
For the field bus connection the 5-pole M12 Micro-Style plug-in connector (plug) as specified by CANopen is used
with the following pin assignment.
Pin No. Signal name
1 Drain (shielding)
2 not used
3 GND
4 CAN HIGH
5 CAN LOW
The bus drivers are supplied internally via a voltage source which is galvanically isolated from the supply voltage.
For this reason it is not necessary for separate voltage to be supplied from the bus via pin 2 and pin 3.
