Basic information
Danger due to incorrect electrical connection
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.
→
After connection but prior to applying the voltage, observe the <Commissioning>
and <Test run> chapters.
Wiring diagram/terminal
plan
The pertaining wiring diagram/terminal plan (in German and English language) is
attached to the device in a weather-proof bag, together with these operation
instructions. It can also be obtained from AUMA (state commission no., refer to name
plate) or downloaded directly from the Internet (www.auma.com).
Permissible networks
(supply networks)
The controls (actuators) are suitable for for use in TN and TT networks with directly
earthed star point and a maximum voltage of 690 V AC. Use in IT networks is
permitted while observing the respective <Protection on site> for for maiximum supply
voltages of 600 V AC.
Protection 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 values for respective sizing is derived from the current consumption of
the motor (refer to electrical data sheet) plus the current consumption of the controls.

If controls are mounted separately from actuator (controls on wall bracket): Consider
length and cross section of connecting cable when defining the protection required.
Use appropriate insulation monitors when working in power installations, for example
an insulation monitor measuring the pulse code.
Power supply for the
controls (electronics)
In case of external supply of the controls (electronics): The external power supply
must have a reinforced insulation against the mains voltage in accordance with IEC
61010-1 and may only be supplied by a circuit limited to 150 VA in accordance with
IEC 61010-1.
Potential of customer
connections
All input signals (control) must be supplied with the same potential.
All output signals (status signals) must be supplied with the same potential.
Safety standards
All externally connected devices shall comply with the relevant safety standards.
Cable installation in ac-
cordance with EMC
Signal and bus cables are susceptible to interference.
Motor cables are interference sources.
