●
For device insulation, appropriate (voltage-proof) cables must be used. Specify
cables for the highest occurring rated voltage.
●
Use connecting cables, cable glands, reducers, blanking plugs with a minimum
temperature range of +80 °C.
●
For connecting cables exposed to UV radiation (outdoor installation), use UV
resistant cables.
●
For the connection of position transmitters, screened cables must be used.
Cable installation in ac-
cordance with EMC
Signal and fieldbus cables are susceptible to interference. Motor cables are
interference sources.
●
Lay cables being susceptible to interference or sources of interference at the
highest possible distance from each other.
●
The interference immunity of signal and fieldbus cables increases if the cables
are laid close to the earth potential.
●
If possible, avoid laying long cables and make sure that they are installed in
areas being subject to low interference.
●
Avoid parallel paths with little cable distance of cables being either susceptible
to interference or interference sources.

Wall bracket
The actuator controls are mounted separately from the actuator on a 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 cable set “LSW".
