See the wiring diagrams for instructions how to con-
nect external potential-free contacts for start/stop and
digital function, external setpoint signal and fault sig-
nal.
Connect the wires to the following terminal groups:
Note:
• As a precaution, separate the wires from each other
by reinforced insulation in their entire lengths.
• If no external on/off switch is connected, maintain
the connection across terminals 2 and 3.

TPE wiring diagram
Group 1:
Inputs (external start/stop, digital function,
setpoint and sensor signals, terminals 1-9
and bus connection, A, Y, B).
All inputs are separated from the mains
conducting parts by reinforced insulation.
Group 2:
Output (signal relay).
The output, terminals C, NO and NC, are
galvanically separated from other circuits.
Therefore, the supply voltage or protective
extra-low voltage can be connected to the
output as desired.
Group 3:
Mains supply.
