Linear actuators MC100 • MC103
Operating Manual Version 2.1 - March 2011 15
Damaged cables result in damage to devices!
When lifting the cover you may tear off or damage the cabling inside the cover.
• Carefully remove the cover.
2 Remove the cover (201) carefully.
3 Disconnect the plug-in connection between the main PCB and the (110) cover
(201).
How to attach the cover
1 Plug the previously pulled off cables back into the main PCB (110).
Pay attention to the notches on plug and socket.
Hint: You can mount the cover (201) in four, different, positions each of which is
transposed by 90°. This allows the best possible laying of the connecting cable
for different installations of the linear actuator.
2 Place the cover (201) on top and push it down to make it fit by applying
moderate force.
3 Check the cover for correct fit to ensure air-tightness for the actuator housing.
4.5 Electrical connection
Danger of life caused by incompetent staff!
Electrical connections carried out by unqualified staff may result in death, severe
bodily injury or considerable material damage.
• Make sure that such all work is carried out by qualified staff.
1.3 Personnel on page 5
Risk of injury from electric shock by live parts!
When the supply voltage is turned on there is a risk of electric shock from live
parts.
• Prior to commencing any work, ensure that the actuator is safely disconnected
from the power supply system.
• Secure against unauthorised restarting.
How to prepare the electric connection
1 Ensure that the supply voltage matches the specifications on the type place of
the linear actuator.
2 To avoid breakdown, construct the line diameter according to actuating
performance and required line length.
3 Lay the mains for a supply voltage of > 48 V separate from the signal and control
wires.
When laying cables in a joint cable duct, use shielded control wires.
4 Check the supply voltage.
If the required tolerance is not achieved by a power transformer you will have to
use an AC voltage stabilizer.
