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 with directly earthed star
point. 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.
Protection and sizing on
site
For short-circuit protection and for disconnecting the actuator from the mains, fuses
and disconnect switches have to be provided by the customer.
The current value for sizing the protection is derived from the current consumption
of the actuator (refer to name plate).
We recommend refraining from using residual current devices (RCD). However, if
an RCD is used within the mains, the residual current device must be of type B.
Consider length and cross section of connecting cables between actuator controls
and actuator when defining the protection required.
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.
All connected electric circuits shall comply with the requirements for protective
separation.

●
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.
●
It is advised to use a shielded cable.
●
For connecting cables exposed to UV radiation (outdoor installation), use UV
resistant cables.
●
The cross-sectional area of every protective earthing conductor which does not
form not part of the supply cable or the cable enclosure, shall, in any case, not
be less than:
-
For mechanical protection: minimum 2.5 mm²
-
Without mechanical protection: minimum 4 mm²
●
For the connection of position transmitters, screened cables must be used.
