4.4 Mechanical installation
4.4.1 General installation safety notes
• Never work on the actuator with the power switched on!
• Do not hold the extension tube while the unit is energized.
• Failure modes of the actuator should be considered to ensure it does not create harm.
4.4.2 Basic installation considerations
1. Only mount the actuator using the holes in the rear (a) and front (b) adapters. Check the model
number on the actuator product label (section 4.1) and then look at the ordering key (section 7.2)
to find out your adapter type configuration.
2. Make sure that the actuator mounting position allows access to the cable connector cover plate (c), so
that it can be removed to allow access to the cable connector (section 4.4.4).
