1.9 Installation in Rack
All devices will mount in standard 19-inch racks having sufficient depth and should be mounted with four
standard rack bolts. To avoid the deformation of the chassis it is recommended to mount heavy units on
horizontal brackets.
Please ensure a sufficient airflow. In the case, closed racks are being used rack-fans should be used. For
larger installations one open rack space (1 RU) for every 2 mounted power amplifiers should be provided.
1.10 Power Connection
The power amplifier must be connected only with the attached three-wire safety power cord with protective
conductor (non-fused earthed conductor).
This amplifier is made for use with the mains voltage labeled on the back of the amplifier only. Check the
label on the back panel of the amplifier for the appropriate voltage. Make sure the voltage of your mains
outlet is correct. The power voltage is factory set as labeled on the back panel and cannot be changed
afterwards. Damage caused by connecting the amplifier to improper AC voltage voids the warranty.
Caution
Never isolate the ground of the AC power cords (the non-fused earthed protective conductor) to
eliminate hum-problems.
Always turn off and disconnect the amplifier from the mains voltage before making any audio connections.
As a precaution, turn the audio attenuators on the front panel down during powering up.
The power fuses are located on the back panel of the amplifier and can be accessed from the outside. Use
only the appropriate fuses as labeled.
After properly mounting and connecting the AC cord and the audio connections, the unit can be switched
on.
