Basic information
Electric shock due to presence of hazardous voltage!
Failure to observe this warning can result in death, serious injury, or property damage.
→
The electrical connection must be carried out exclusively by suitably qualified
personnel.
→
Prior to connection, observe basic information contained in this chapter.
Wiring diagram/terminal
plan
The pertaining wiring diagram/terminal plan (in German or English) is attached to
the device in a weather-proof bag, together with these operation instructions. It can
also be requested from AUMA (state order number, refer to name plate) or
downloaded directly from the Internet (http://www.auma.com).
Permissible networks
(supply networks)
The actuators are suitable for use in TN and TT networks. For IT network, a suitable,
approved insulation monitor measuring the pulse code is required.
Current type, mains
voltage, mains fre-
quency
Type of current, mains voltage and mains frequency must match the data on the
name plate.
For short-circuit protection and for disconnecting the actuator from the mains, circuit
breakers with the following sizing/characteristics have to be provided by the customer:

Potential of customer
connections
All input signals (control inputs) must be supplied with the same potential.
All output signals (status signals) must be supplied with the same potential.
Safety standards
Safety measures and safety equipment must comply with the respectively valid
national on site specifications. All externally connected devices shall comply with
the relevant safety standards for the place of installation.

●
We recommend using connecting cables and connecting terminals according
to rated current (I
N
) (refer to motor or electrical data sheet).
●
For device insulation, appropriate (voltage-proof) cables must be used. Specify
cables for the highest occurring rated voltage.
●
Use connecting cable with appropriate minimum rated temperature.
●
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.
