Electric shock due to presence of hazardous voltage!
Risk of death or serious injury!
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.
Risk of overheating during operation with mounted transport protection!
Prior to connection, remove transport protection from cooling fins.
Figure 16: Remove transport protection
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).
The actuators are suitable for use in TN and TT networks with directly grounded star
point for nominal voltages up to maximum 480 V AC. Use in IT network is permissible
for nominal voltages up to maximum 480 V AC. For IT network, a suitable, approved
insulation monitor measuring the pulse code is required.
Type of current, mains voltage and mains frequency must match the data on the
actuator controls and motor name plates. Also refer to chapter <Identification>/<Name
plate>.
