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.
Information on installation with wall bracket
The permissible cable length between actuator controls on wall bracket and
the actuator amounts to 100 m maximum.
We recommend using an AUMA "LSW" cable set.
If the AUMA cable set is not used:
- Use suitable flexible and screened connecting cables.
- Use separate CAN bus cable of 120 Ohm character impedance for MWG
(e.g. UNITRONIC BUS-FD P CAN UL/CSA - 2 x 2 x 0.5 mm², manufacturer:
Lapp).
- Data cable connection: XM2-XA2 = CAN L, XM3-XA3 = CAN H.
- Voltage supply MWG: XM6-XA6 = GND, XM7-XA7 = + 24 V DC (refer to
wiring diagram).
For the electrical connection at wall bracket [3], the terminals are made as crimp
connections.
- Use a suitable four indent crimp tool for crimping.
- Cross sections for flexible wires:
- Control cables: max. 0.75 to 1.5 mm²
- Mains connection: max. 2.5 to 4 mm²
