Installation
Type 3281
DANGER
Risk of injury due to high pressure and escaping medium.
If direction of rotation is incorrect, the body connection can detach.
▶
Rotate the actuator only in the specified direction of rotation.
→
Move the actuator into the required position by turning it
clockwise (seen from above).
7.6
Installing the device electrically
All electrical inputs and outputs of the device are
not
galvanically isolated to the supply voltage.
DANGER
Risk of injury from electric shock.
▶
Before working on the system or device, switch off the power
supply and secure to prevent reactivation.
▶
Observe any applicable accident prevention regulations and
safety regulations for electrical devices.
NOTE
Damage to the motor valve due to incorrect supply voltage.
▶
Supply voltage must correspond to the voltage indicated on
the type label.
▶
If the earth is not connected, this represents an infringement
of the legal regulations of EMC.
→
Connect the motor valve according to the table. After applying
the operating voltage, the motor valve is ready for operation.

The threaded sleeve of the M12 circular plug is connected
to the actuator cover. The actuator cover must be con-
nected to a suitable earthing connection.
NOTE
To ensure electromagnetic compatibility (EMC), make sure that
the cable is as short as possible and the cross-section is as
large as possible.
