●
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).
●
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 (EWG,
RWG, IWG, potentiometer) do not belong to this group. They may not be sub-
jected to an insulation test.

Application
Parking frame for safe storage of a disconnected plug or cover.
For protection against touching the bare contacts and against environmental
influences.
Risk of explosion!
Risk of death or serious injury!
→
Prior to opening the device (removing the plug) ensure that the device is free
of gas and voltage!
→
Do NOT switch on voltage in potentially explosive atmospheres.
For PAFEx 01.1, separate operation instructions are available.
