11 Electrical connection
For the devices, a distinction is made between two voltages:
– U
S
to supply the communications power and the sensors (always required),
– U
A
for supplying the actuators, only required for devices with fixed outputs or
for additional devices�
All supply voltages are connected via M12 connectors�
Damage to the electronics
► Connect both supply voltages completely (to +24 V and GND)�
Do not connect several supply voltages via one GND, as this will exceed the current rating of the
contacts�
11.1 Supply voltages U
S
and U
A
The voltages U
S
and U
A
are fed in at connection X31�
Power supply U
S
is required to supply the communications power of the device
electronics and to supply the sensors� It must be connected to every device� If this
supply voltage is disconnected, the device will not work�
► Install the power supply for the device electronics independently of the power
supply for the actuators�
