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 .
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.
