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. Use in IT networks is permitted while heeding the indications with regard to
on-site protection.
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
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.
For IT networks, a suitable, approved insulation monitor measuring the pulse code
is required.
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): For external electronics supply,
the power supply of actuator controls must have an enhanced isolation against mains
voltage in compliance with IEC 61010-1 and the output power be limited to 150 VA.
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
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 applicable for the place of installation.
All connected electric circuits shall comply with the requirements for protective
separation.
