8.5Installation

The power amplifier is suitable for either table-top or 19-inch rack installation. Four feet (for table-top use) and two brackets (for rack installation) are supplied.

Caution

Due to the weight of the power amplifiers, it requires two persons to lift and install them in a 19-inch rack.

Caution

When mounting the brackets to the unit, use the screws that are supplied with the brackets, four longer ones and two shorter ones. Use two screws of 7.5 mm thread length at the front side of each bracket, use a short screw of 5.2 mm thread length at the rear side of each bracket. Do not use screws with a thread length of >10 mm for the front positions or screws with a thread length of >5.7 mm at the rear postion; longer screws may touch or damage internalparts of the unit.

figure 8.16: Installation

Ensure there is enough space for the cool air flow to enter and the warm air flow to leave the power amplifier. Preferably, the power amplifiers are installed in a closed 19" rack that has one cool air inlet protected with a dust filter (see figure 8.17) to prevent dust from entering the equipment.
