5.4.1 Electrical connection
5.4.1.1 Connection
Where relay points and electronic load relays are particularly sensitive a coil should be connected in
series additionally to each relay point
- Contactors of 16A and upwards do not need a safety circuit.
ATTENTION !
- Work on electrical systems or equipment must only be carried out by qualified
electricians or by trained individuals under the guidance and supervision of a qualified
electrician in compliance with regional electrical requirement and regulations.
- When connecting the electronics the supply line must be disconnected from the mains
(not live) during connection work. It must be impossible to switch the power on
unintentionally while the mains are disconnected in this way. Failure to comply may
result in death, serious injury or substantial damage to property.
- The mains voltage must coincide with the values indicated on the rating plate.
- Never touch live parts while carrying out adjustments!
- Exercise particular caution when working with voltages higher than 24 V!
- Never insert or withdraw modular isolating terminals that are still live!
- Only one actuator can be connected.
- The actuator lift range must not be overtravelled when carrying out adjustments;
risk of damage.
- Make sure the motor connected in the actuator is switched off in the final
positions according to the travel or torque.
ATTENTION
!
- A voltage is induced in the thrust actuator motor. This induction voltage may be higher
than the operating voltage.
- For this reason relays and electronic load relays for thrust actuator control require a
protective circuit. The contacts of unprotected relays may stick after a while.
- This may result in reversed directions of rotation or defective switch-off
Recommended safety circuit for relays and electronic load relays:
Connect a varistor or RC module parallel to each relay point.
Varistor
S10K385 to S10K460
RC module
100 Ohm / 100nF
Recommended coil:
Toroidal coil
2mH / 2A
