When left one phase of the mains power, that is not what it feeds the HC5-10, the
transmitter reduces its RF output power to a value that doesn't exceed the 5KW. If the
power of programmed regime is inferior to the value of 5KW, doesn't happen any
reduction.
When left two phases of mains power, but stays the phase that feeds the HC5-10, the
transmitter reduces its RF output power to a value that doesn't exceed 1KW. If the
power of programmed regime is inferior to the value of 1KW, doesn't happen any
reduction.

Risks for the HC5-10 system with PJ2000M-C
Some operational situations are potentially harmful for some part of the system.
When the cable of interconnection of the signals of command doesn't connect all the
apparatuses of the system, the amplifiers not connected doesn't react the deriving
commands from the HC5-10 apparatus . This constitutes possible cause of permanent
damages to the HC5-10.
If the connection of the neutral of the mains power stops in any part of the electric
installation, inside or outside of the apparatus, are possible permanent SERIOUS
DAMAGES to all the apparatuses of the system.
The apparatus HC5-10 MUST be connected to its driver/ exciter apparatus through
a cable that allows the interrupt of the oiperation in case of intervention in protection.
This connection could be of two types:
•
Signal of low voltage that cuts off the power of the driver/exciter system.
•
Feeding of the exciter connected to the plug of mains voltage foreseen, and
available on the rear panel.
The first solution is indispensable when HC5-10 system with PJ2000M-C is connected
to the telemetry, whose circuits are install on the exciter.
If at least one of the two connections doesn't come done, are possible permanent
damages to the HC5-10.
The RF power cables that connect the output of each PJ2000M-C amplifier with the
HC5-10 combiner must be well locked. If the contact between the connectors is not
correct, leaks of energy in RF could be verified. This energy has the power to influence
dangerously on the behavior of electric circuits of other apparatuses in the vicinities
of the transmitter beyond that on the same transmitter. The power in game on these
connections is potentially able to generate overheatings with possible fire of the cables.
WARNING: The interconnection cables between amplifiers and HC5-10
contains TEFLON, the combustion of the TEFLON generates HIGHLY TOXIC
GAS for each living being.
The amplifier requires high values of current from the mains. If the cables that furnish
the electric general feeding are not well locked, fires could be verified.
