10.5.2 Installing the programming unit
Route a 4-core bus cable from
mounting position of the programming unit. Use a screened
electronic cable such as LiYCY 2x2x0.8
cable parallel to a three-phase cable.
The BUScable must protrude 20 to 30 cm out of the wall to allow
installation.
Remove programming unit from the wall mounted enclosure
Releasethe locking tab found in the opening on the under-
side of the wall mounted enclosure. Pressthe locking tab
with a screwdriver.
Installation with a flush box
For securing to a wall we recommend using a flush box,which can
hold the part of the bus cable protruding from the wall.
Make sure that the screws supporting the flush box are ar-
ranged either vertically or horizontally opposite one another.
Route the bus cable through the aperture in the wall mount-
ed enclosure from the back.
Installation without a flush box
To secure the wall mounted
(Ø 5 mm).
When routing the BUScable, be careful not to damage the
cable when drilling the fixing holes.
In the area around the cable entry (behind the wall mounted en-
closure), a reservoir needs to be made to hold 20 to 30 cm of data
cable.
Break out one of the knock-outs
