INSTALLATION MANUAL
5. Electrical connection and commissioning
Connecting and commissioning may only be carried out by qualified staff.
Risk of injury or death! Risk of injury or death due to electrical or mechanical forces!
Before starting to work on the motor gearbox or related parts, always switch the power off at the master
switch or operating switch and lock it out with a padlock to prevent switching on again.
5.1 Mains connection for single-phase AC motors
Caution
The maximum permissible deviation of the mains voltage from the voltage stated on the rating plate of the
motor is 5%.
The wiring diagram can be found in the appendix on page 24.
1. Remove the cover from the terminal block of the electric motor;
2. Insert the cable through the cable gland and rubber gasket;
3. Connect the green/yellow lead to the PE terminal (earth);
4. Connect the neutral lead (N) to terminal U1 and the live lead (L) to terminal V1 or W1 as shown on the wiring
diagram, depending on the desired direction of rotation;
5. Using a hex bit, move the motor gearbox to a position between the two limit switches;
6. Check the direction of rotation of the output shaft in relation to the limit switch and the control cabinet. If
necessary, switch the wiring between V1 and W1 (see diagram);
7. Fit the terminal block cover and gasket back on the motor and tighten the cable gland;
8. Make sure that the cables are clear of any moving parts.
5.2 Mains connection for three-phase AC motors
Caution
The maximum permissible deviation of the mains voltage from the voltage stated on the rating plate of the
motor is 10%.
Attention!
Swapping the supply voltage phase connections changes the direction of rotation of the drive. A switch in
phase will affect the operation of the limit switch mechanism.
The wiring diagram can be found on page 23.
1. Remove the cover from the terminal block of the
electric motor;
2. Insert the cable through the cable gland and rubber
gasket;
3. Connect the green/yellow lead to the PE terminal
(earth);
4. Connect phase L1 to terminal U1, phase L2 to terminal
V1 and phase L3 to terminal W1 (see diagram)
5. Using a hex bit, move the motor gearbox to a position
between the two limit switches;
6. Check the direction of rotation of the output shaft in
relation to the limit switch and the control cabinet, and
swap two phases if necessary;
7. Fit the terminal block cover and gasket back on the
motor and tighten the cable gland;
8. Make sure that the cables are clear of any moving
parts.
