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 (in German and English language) is
attached to the device in a weather-proof bag, together with these operation
instructions. It can also be obtained from AUMA (state commission no., refer to name
plate) or downloaded directly from the Internet (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 consumption Mains voltage
575 mA 100 to 120 V AC (±10 %)
275 mA 208 to 240 V AC (±10 %)
160 mA 380 to 500 V AC (±10 %)
500 mA 24 V DC (+20 %/–15 %) and AC motor
Table 6: Maximum permissible protection
Max. protection Rated power Switchgear
16 A (gL/gG) up to 1.5 kW Reversing contactor A1
16 A (g/R) I²t<1,500A²s up to 1.5 kW Thyristor B1
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.
Safety standards
All externally connected devices shall comply with the relevant safety standards.
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.
●
For the connection of remote position transmitters, screened cables must be
used.
