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 (both in German and 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. Use in IT networks is permitted while observing the respective <Protection on
site>.
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 value for respective sizing is derived from the current consumption of
the actuator (refer to electrical data sheet).
The actuators are suitable for use in current circuits with a maximum short-circuit
1-phase AC current value of 5,000 A root-mean-square (R.M.S). The output data of
the fuses to be provided on site must not exceed the following values: 15 A/250 V
at a maximum mains current of 5,000 A AC.
Use appropriate insulation monitors when working in power installations, for example
an insulation monitor measuring the pulse code.
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.
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
61800-5-1 and may only be supplied by a circuit limited to 150 VA in accordance
with IEC 61800-5-1.
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.
All connected electric circuits shall comply with the requirements for protective
separation.
Cable installation in ac-
cordance with EMC
Signal and bus 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 bus 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 long parallel paths with cables being either susceptible to interference or
interference sources.
