The Failsafe actuator is mounted and installed in the same way as a
standard actuator, with the following exceptions:
• There are routines to follow for the storage and installation caused by
battery considerations, see information in section 11.3.2 on page 65.
• There are considerations to make when you open the actuator, see
11.5.2 below.
• The interface communication box is fastened to the failsafe module with
nuts instead of screws.
• Connection of the battery cable sees 11.8.2 on page 74, steps 12 – 16.
See Chapter 4 Mounting and Installation on page 34 on how to connect the
external power and signal cables to the communication interface unit.
