Mounting

Note
Strong electromagnetic fields can impair the function of the device.
Î Make sure the device as well as the system are not exposed to strong
electromagnetic fields.
The device must only be located in dry interior rooms.
In order to prevent disturbances caused by electromagnetic fields, pay attention to
separate routing of mains cables and bus cables.
4 self-adhesive, skid-proof rubber pads are included with the device. If necessary,
these can be affixed to the corresponding molds on the base part of the housing to
ensure a secure placement of the device without wall mounting.
If desired, the device can be mounted to a wall. To do so, proceed as follows:
Î Mark the desired position on the wall.
Î Drill and prepare the hole with a wall plug and screw.
Î Hang the housing from the upper fastening point and mark the lower fastening
point (centres 70 mm).
Î Insert lower wall plug.
Î Fasten the housing to the wall with the lower fastening screw and tighten.

Electrical connection

ATTENTION! ESD damage!
Electrostatic discharge can lead to damage to electronic compo-
nents!
Î Take care to discharge properly before touching the inside of
the device! To do so, touch a grounded surface such as a radi-
ator or tap!
ATTENTION! Short circuit!
A short circuit can lead to damage to electronic components!
Î Establish the power supply only after you have connected all
cables required to the terminals and closed the housing.
Note
Connecting the device to the power supply must always be the last step
of the installation!
If the mains adapter or its cable is damaged, it has to be replaced by an identical
mains adapter, which is available from the manufacturer or its customer service.
Do not use the device if it is visibly damaged!
The device is to be connected to the controller via the pre-connected VBus
(terminals C and D). The corresponding terminal allocation is described in the
controller manual.
The VBus cable can be extended using the terminal block included and a 2-wire
®
cable.
With the VBus ® -Repeater distances of up to 150 m between the controller and the
interface adapter are possible.
