Application
The wall bracket allows separate mounting of actuator controls and actuator.
●
If the actuator cannot be accessed safely.
●
If the actuator is subjected to high temperatures.
●
In case of heavy vibration of the valve.
Observe prior to connec-
tion
●
Permissible length of connecting cables: max. 100 m.
●
If the actuator is equipped with a position transmitter (RWG): Connecting cables
must be available as shielded version.
●
Versions with potentiometer in the actuator are not suitable.
●
We recommend: AUMA cable set LSW1.
●
If the AUMA cable set is not used: Use suitable flexible and screened connecting
cables.
●
When using connecting cables, e.g. of the heater or switch, requiring direct
wiring from the actuator to the XK customer plug (XA-XM-XK, refer to wiring
diagram), these connecting cables must be subject to an insulation test in
compliance with EN 50178. Connecting cables of position transmitters (RWG,
IWG, potentiometer) do not belong to this group. They may not be subjected
to an insulation test.
