7. INSTALLATION

7.1. Safety instructions

DANGER!

Risk of electric shock!

There is a serious risk of injury when reaching into the device.

• Always disconnect the power and secure it from re-activation

before removing the cover, disconnecting the gears or using the

lever.

• Connect several rotary actuators always with phase separation

via a switch!

• Protect the rotary actuators with a mains-operated fuse!

• Observe applicable accident prevention and safety regulations

for electrical equipment!

WARNING!

Danger - improper installation!

Improper installation may result in injuries as well as damage to

the device and the area around it.

• Installation may be carried out by authorised technicians only

and with the appropriate tools!

Danger due to unintentional activation of the device!

Unintentional activation of the device during installation may result

in injuries and damage.

• Take appropriate measures to prevent the device from being

accidentally actuated.

We recommend an actuator designed with 1.5 times the

maximum torque of the fitting (with 2 times the maximum

torque for variable speed actuators).

7.2. Installing the rotary actuator

The rotary actuator is supplied with the presetting <Closed>.

The rotary actuator can be fitted to a ball valve or flap valve via the

following fastening options:

• ISO F05 (4 x M6 with a flange Ø of 50 mm)

• ISO F07 (4 x M8 with a flange Ø of 70 mm)

• ISO F10 (4 x M10 with a flange Ø of 102 mm)

7.2.1. Shaft end

The sizes of the inner star shape of the shaft end depend on the size of

the actuator. Only the standard size of the inner star shape is enclosed

with each actuator (see table).

Actuator size [Nm] Standard size of the inner star shape [mm]

25 17 / 11

45 / 75 17 / 14

100 / 150 / 300 22 / 17

Important information for continuous function:

Do not attach rotary actuator head first!

Otherwise the medium may run out of the fitting into the

actuator.
