Do not mount on or against highly combustible materials. • The units should be provided with an equipotential bonding wire (Cu, at least 4 mm2). • The safety regulations set out in the current EN 60728-11 and EN 60065 standards must be complied with. • Suitable securing fastenings: Wood screws, max O: 4.5 mm • Connector: HF plug 75 . (series F) to EN 61169-24. General information on installation Installation of an amplifier in a satellite reception system In principle, the amplifier can be built into any position in the Sat reception system (see section “System example”). The following is to be observed: -the level on the input should fall within the range between 50 to max. 80 d.V and -the multi-switches following are not to be overdriven Levelling the amplifier In order to define the level, it is recommended to use an antenna measuring instrument, e.g. MSK 200. You can adjust the gain in 1-dB increments (see picture on right). The attenuator affects all Sat-range amplifier units at the same time. To equalise attenuation slopes, such as in long cable lengths, the amplifier’s pre-equalisation can be set to 2, 4 and 6 dB. The terrestrial amplifier is adjusted with its own attenuator. Connection of the amplifier to other units of the Sat reception system The easiest and quickest way to connect the amplifier to, e.g. a EXR 2558/EXR 2998 multi-switch is by using the optional connector EMU 250 (see picture on right...
