Control Terminal Wiring

All analog signal cables should be suitably shielded.
Twisted pair cables are recommended.

Power and Control Signal cables should be routed
separately where possible, and must not be routed parallel
to each other.

Signal levels of different voltages e.g. 24 Volt DC and 110
Volt AC, should not be routed in the same cable.

Maximum control terminal tightening torque is 0.5Nm.
 Control Cable entry conductor size: 0.05 – 2.5mm
2
/ 30
– 12 AWG.
Control Terminal Connections
Control Switched Units:
May use the built in control switch and potentiometer, or external control signals connected to the
control terminals.
Non-Switched Units:
Require external control signals to be connected to the control terminals.

NOTE
For Switched units, the internal pot is selected by default in P-16.
For Non-switched units, an external pot or 0 - 10 V reference may be connected. Other
signal types may also be used, set P-16 to the correct format.
NOTE Additional functions are possible, refer to the online documentation for further information.
