ATTENTION! ESD damage!
Electrostatic discharge can lead to da-
mage to electronic components!
Î Take care to discharge properly
before touching the inside of the
device. To do so, touch a grounded
surface such as a radiator or tap!
The unit must only be located in dry interior locations. It
is not suitable for installation in hazardous locations. Please
pay attention to separate routing of sensor cables and mains
cables.
The interface adapter is light and small enough to not re-
quire any form of mounting. It can be placed on a suitable
surface (pay attention to the ambient temperature!).
Four self-adhesive, skid-proof rubber pads are included with
the adapter. If necessary, these can be affixed to the corre-
sponding molds on the base part of the housing to ensure
a secure placement of the device without wall mounting.
If desired, the interface adapter can be mounted to a wall:
Î Mark the desired hanging position on the wall
Î Drill and prepare the hole with a wall plug and screw
Î Hang the device onto the screw
Î Mark the position for the mounting screw (distance to
hanging point centre: 70 mm)
Î Drill and prepare a hole with a wall plug
Î Hang the device and fasten it by means of the second
screw
For wall mounting, opening the housing is not required.
Opening the housing is only required for access to the
terminals.
Î To open the housing, unscrew the cover screw and pull
off the upper part of the housing
Î To close the housing again, relocate the upper part of
the housing and refasten the cover screw
