3.5 Powering up the amplifier
1.
Verify if the voltage present is in accordance with the amplifier specifications and the network design drawing
calculation. Please make sure that the presence of input voltage is in accordance with amplifier specifications and
network design drawing calculation.
2.
The output ports should be connected first and the input port last as this will power the amplifier.
3.
Connect the earthing/grounding wire (
Fig. 3
) (in accordance with local electrical installation regulations)
on the right-hand side of the housing. The maximum diameter of the grounding wire is 3.8mm.
4.
Remove the AUX DS 0 dB attenuator temporarily to protect the amplifier from eventual high input RF levels.
The attenuator can be re-installed once the electronic input and interstage attenuator have been configured to
10 dB or more (as a starting point).
5.
Switch on the power and check that the status LED is steady green when power is present.
