3.5 Connecting the power supply
Via screw terminal blocks
Connect a DC voltage source (19.2 V ... 30.5 V DC) to the wireless module. The nominal
voltage is 24 V DC. Supply voltage to the device via terminal blocks 1.1 (24V) and 1.2(0V).
In the case of a connection station, it is sufficient to supply the first device in the group.
Figure 3-6 Connecting the power supply
In order to prevent damage to the wireless module, we recommend installing a surge pro-
tective device. Make sure the wiring between the surge protective device and the wireless
module is as short as possible. Please also observe the manufacturer’s specifications.
With a system power supply via the bus foot
If DIN rail connectors are used, you can use the MINI-SYS-PS 100-240AC/24DC/1.5 sys-
tem power supply (Order No. 2866983). Connect the system power supply using two DIN
rail connectors to the left of the device.
Figure 3-7 Supply via system power supply
– Parallel supply via the screw terminal blocks and with a system power supply via the
bus foot is not possible.
– For redundant supply, you can connect a second MINI-SYS-PS 100-240AC/24DC/1.5
system power supply.
