4 Installation

This amplifier is built for 483 mm racks (19"). This rack should be a double-door rack where front panel and
rear panel can be opened. The rack should be provided with a cooling fan. When mounting the amplifier 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 amplifier with four screws M6 in the rack. If several devices are to be installed, make sure
that you leave 1 unit (1 U) space between the devices. Be careful when mounting the amplifier into the rack.
Put the heaviest devices into the lower part of the rack. Be aware that fastening the amplifier with four
screws on the front panel is not enough. In order to ensure safety, additional fastening by using ground and
side bars is necessary.
If racks are to be transported or used for mobile use, fasten the devices additionally by connecting the rear
brackets with the side or ground bars of the rack. Thus, the amplifier cannot be pushed backwards. The front
panel alone is not designed to absorb acceleration forces occurring during transportation.
