„
Setting up
Using the basic device as a table device:
Attach the rubber feet supplied with the device to the bottom of the
device.
–First remove the protective film from the adhesive film of the rubber
feet.
–Attach one rubber foot approximately 2 cm from each corner of the
device.

Installation
The devices are designed to be mounted in a 19" cupboard.
Make sure there is sufficient ventilation. If necessary, provide a fan for
the 19" cupboard. This will prevent the basic devices from overheating.
Measure the depth of the 19" cupboard so as to allow the mains cable,
and any power supply cables, to be fitted from the back, and the data
cables to be fitted from the front.
If you are operating the device in a 19" switch cabinet, you must install
sliding/mounting rails (not included in the delivery) to hold the weight of
the device.
Warning
If the device is installed in a 19" switch cabinet without sliding/
mounting rails, increased vibration can cause damage to the de-
vice and/or its modules.
