AUMA AMB 01.1 - Electrical Connection; Basic Information

5. Electrical connection
5.1. 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).
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.
Table 5: Current consumption controls
Max. current consumptionMains voltage
575 mA100 to 120 V AC (±10 %)
275 mA208 to 240 V AC (±10 %)
160 mA380 to 500 V AC (±10 %)
500 mA24 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.
Power supply for the
controls (electronics)
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.
Type of current, mains
voltage and mains fre-
quency
Type of current, mains voltage and mains frequency must match the data on the
motor name plate.
