Motor connection
Please also note the information about the installation of an external motor protection circuit breaker - see
Section 1.6.2, Seite 5.

Three-phase motor:
Connection of the three-phase system with positive phase sequence (L1, L2, L3):
Clockwise rotation of the actuator:
–
Phase
L1
to
U1
–
Phase
L2
to
W1
–
Phase
L3
to
V1
Counterclockwise rotation of the actuator:
–
Phase
L1
to
U1
–
Phase
L2
to
V1
–
Phase
L3
to
W1
Caution: Before starting up the actuator it is absolutly necessary to check the phase
sequence of the three-phase system on correctness and if necessary to correct it!
Caution:
When connecting the motor via the motor clamping board or the terminal-strip wiring
, the clamps are labelled with U1, V1, W1. With plug connection, refer to the inscription on the wiring
diagram.
•
One-phase motor
These motors are standardly wired to the terminal strip with the labeling R, N, L
Clockwise rotation of the actuator:
–
neutral conductor to N
–
phase to R
Counterclockwise rotation of the actuator:
–
neutral conductor to N
–
phase to L
Caution:
With plug connection, refer to the inscription on the wiring diagram.
WARNING: Observe the technical data sheets of the built-in components.
Note: Actuators with an output speed of less than 120 rpm interlock automatically. Whenever
switched off, actuators not equipped with automatic interlock (
≥
120 rpm), will relieve stress via
the torque. The torque switch will then return to its neutral position.
To prevent undesired re-start in the same direction,
the torque switches of actuators with no
automatic interlock must be locked electrically.
If electrical connection is not immediately followed by start-up and if the unit is located outdoors, the heating
resistor should be promptly activated (Be sure the voltage is in accordance with the proposed wiring diagram!)
or the silica gel should be left in the indicator unit
Caution:
See Section 2, page 7 of the operating instructions.
