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.
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).
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.
Table 5: Current consumption controls
Mains voltage
100 to 120 V AC (±10 %)
208 to 240 V AC (±10 %)
380 to 500 V AC (±10 %)
24 V DC (+20 %/–15 %) and AC motor

If controls are mounted separately from actuator (controls on wall bracket): Consider
length and cross section of connecting cable when defining the protection required.
If the controls (electronics) are supplied externally with 24 V DC, the power supply
is smoothed via an internal 1,000 μF capacitor). When selecting a power supply,
care must be taken to consider the capacitor inrush current upon powering the unit
up.
All externally connected devices shall comply with the relevant safety standards.
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.
For the connection of remote position transmitters, screened cables must be
●
used.
