5. INSTALLATION
The processor is provided for use as a table top unit or for installation into a 19" rack (483 mm). For rack
installation, you need the optional mounting kit. The rack should be a double-door rack where you can open
the front panel and the rear panel. The rack should be provided with a cooling fan. When mounting the
device into the rack, please make sure that there is enough space around the device so that the heated air
can be passed on. Steady overheating will damage your device. You can fix the device with four screws M6
in the rack. If several devices are to be installed, make sure that you leave 1 unit space between the devices.
