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.
After connection but prior to applying the voltage, observe the <Commissioning>
and <Test run> chapters.
The pertaining wiring diagram/terminal plan is in the cover of the electrical connection.
The operation manual is attached to the device in a weather-proof bag.
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 are derived from the current consumption
of the motor (refer to electrical data sheet) plus the current consumption of the
actuator controls.
Table 6:
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.
Type of current, mains voltage and mains frequency must match the data on the
motor name tag.
