Type 3274 Actuator
1. Remove the housing cover on the side.
2. Route the connecting cables through the
cable entries on the housing onto the ter-
minals and fasten them.
Voltage must always be applied to termi-
nals N and L. If no supply voltage is ap-
plied, the actuators will remain in their
last position. Actuators with fail-safe
function will move to their fail-safe posi-
tion.
3. Connect grounding conductors to the
separate grounding conductor terminals
on the inside of the housing.
4. Remount the housing cover.
Fuse:
The PCB of the motor’s electronics includes a
bracket with a 5 x 20 mm glass tube fuse:
for 230 V, 50 Hz = T 1 (1 A, time-lag)
for 110 V, 50 Hz = T 1.25 (1.25 A, time lag)
for 24 V, 50 Hz = T 6.3 (6.3 A, time-lag)

Note!
The controller output relays used to control the
input signals aL (stem extends) and eL (stem
retracts) must be operated and connected
using terminal 81 (same potential) only.
