Design and function
Only use one single power voltage source to connect to terminals 1, 2, 3 or 4. Do not
supply power voltage from different voltage sources to one actuator!
Connecting the actuator with an open-ended wire through the cables glands provided
Connect the protective earth (PE) provided on the main board. Use a suitable isolated
ring terminal lug, accepting 0.5 – 1.5mm
Min. cable length earth wire (PE):
Ensure that the minimum length of
the earth wire (PE) is 2.5cm (1") longer
than voltage wires.
This will ensure that the PE conductor
is the last wire to take the strain in
case the cable gland fails.
Ensure a min. bolt torque of 1.5 – Nm!
Only use the cable glands provided EXW. After cables had been inserted check that the gland is sufficiently closed
(wrench size 24mm) and that the gasket clasps the connection cable completely to ensure water protection & strain
relief.
Ex factory, the position feedback is wired as a normally closed contact (NC). On site,
this might also be implemented as a normally open contact (NO), subsequently.
Standard delivery is with a unit plug for position feedback OPEN/CLOSE. A unit plug
with additional pin for MIDDLE feedback can be ordered as an accessory or special
configuration. Each actuator is provided with this functionality. Connection via cable
gland is also possible.
