1)
The enabling current paths must be supplied by the same voltage supply.
2)
The enabling current path and the external device monitoring (EDM) must be wired within the control
cabinet.

•
Use with restart interlock, with external device monitoring (EDM): Connect the N/C contacts of the
actuators between voltage supply U
v
, the N/O contact of the reset pushbutton and S1.
•
Use with restart interlock, without external device monitoring (EDM): Connect the N/O contact of
the reset pushbutton between S1 and voltage supply U
V
.
•
Use without restart interlock, with external device monitoring (EDM): Connect the N/C contacts of
the actuators between U
V
and S1.
•
Use without restart interlock, without external device monitoring (EDM): Connect U
V
and S1 with a
wire jumper.
