DANGER
!
Risk of electric shock.
Before installing electrical accessories, switch off the power supply and disconnect the signal
input.
Tip
We recommend applying a small amount of lubricant (e.g. Vaseline) to the spindles on the
gear faces and to the sides of the cogs.
Note
To undo the screws on the housing cover, use a Pozidriv PZ2 screwdriver to get enough hold
on the screw heads.
