Switch on
X
Before switching on check whether the following supply
voltages are available:
• Supply voltage for PLC,
• the 24 V DC device supply voltage on the POW terminal of
the SmartWire-DT gateway and on an optionally used
power feeder module,
• the 24 V DC control voltage for contactors on the AUX
terminal of the SmartWire-DT gateway and on an option-
ally used power feeder module,
• the external 24 V DC control voltage for contactors, in
case you are using a switch cabinet bushing SWD4-SFL8-
20/SWD4-SML8-20 with a 24 V DC external supply.
Check whether:
• All plugs on the SmartWire-DT cable are correct, i.e. are
connected in accordance with the installation instructions
in the subsection „Fitting SmartWire-DT ribbon cable with
plugs“, page 83.
• The plugs for all SmartWire-DT slaves are plugged in.
• The sensor/actuator connections for the SmartWire-DT
I/O modules are connected correctly.
• The field bus connection between the SmartWire-DT
gateway and the controller is plugged in.

Caution!
Connect spring-cage terminals “A” and “B” in accor-
dance with the Fig. 25, page 73, if you would like to use
the switch cabinet bushing without an external power
supply. In this case you will work with the 24 V DC control
voltage of the connected SmartWire-DT gateway or power
feeder module.

Danger!
If you have already integrated an SmartWire-DT slave into
a system, secure the endangered operating ranges.
