6 Installation Instructions
Installation work of any kind for the actuator may only be performed by qualified personnel.
6.1 Mechanical connection
Check,
• whether the fitting flange and actuator flange match up
• whether the drilled hole matches up with the shaft
• whether there is sufficient engagement of the fitting shaft in the actuator hole
WARNING: The actuator must not be electrically supplied during the installation work!
NOTE: On delivery and as long as the Failsafe actuator is not electrically connected, it is in the Failsafe position.
Make sure the fitting is in the same position as the actuator:
• For a “Failsafe open” actuator, the fitting has to be completely open.
• For a “Failsafe close” actuator, the fitting has to be completely closed.
In general, heed the following instructions:
• Clean the bare parts on the actuator coated with rust protectant.
• Clean the mounting surface for the fitting thoroughly.
• Lightly grease the fitting shaft.
• Set the actuator in place.
• Make sure of centred positioning and that the contact surface of the flange is full.
• Fasten the actuator with suitable bolts:
– Minimum strength grade: 8.8 or A2-70
– Ensure sufficient thread engagement (min. 1xd)
CAUTION: Screws, that are too long may go against the thread root, creating the risk of the actuator moving
radially vis-à-vis the fitting. This may lead to the bolts shearing off.
NOTE: Unsuitable bolts may result in the actuator falling off!
• Tighten bolts to the correct torque, alternating between bolts on opposite sides
