4. Warning!
Before connecting this product to the AC supply verify that the model supplied is
configured for the correct line voltage be it 115Vac 230Vac or 240Vac. Failure to do
this may cause extensive damage to the amplifier.
Dangerous voltages are present inside this product, AC Line Voltage 230/240Vac,
HV 380Vdc and RF voltages. There are no user serviceable parts inside and the
cover must not be removed by the user under any circumstances especially whilst
the AC power cord is connected. Service to this product must only be carried out by
qualified service technicians.
This product is capable of producing high levels of RF energy so it is assumed that
the user be familiar and qualified to use this apparatus before any connections are
made to it. Making sure and being confident with any equipment connected to the
amplifier is suitably rated for the output power. Antennas, Baluns, Feeders, ATU’s
must all be capable of handling 500W continuously at the frequency of operation.
The amplifier must be connected to the station RF ground via the ground stud on the
rear panel
h
, which should be properly implemented, by means of a short and low
impedance connection usually by means of a heavy copper strap. This will decrease
noise problems in reception and eliminate the possibility of high RF voltages
appearing on the chassis of the amplifier and other metallic equipment in the station
that the operator may come into contact with. This can be due to unbalanced
antennas or static build up. (Do not use gas supply tubing or water supply tubing as
an RF ground!!). See Section Grounding.
Antennas connected to this amplifier should be mounted well away from the
possibility of human or animal contact to avoid the risk of electrical shock and RF
exposure.
Keep fluids well away from the amplifier and do not use the amplifier if it is subject
to direct sunlight for a long period of time.
If during operation any abnormal noise / odour is noticed, switch off the amplifier
immediately, check all connections to the amplfier and if necessary return the
amplifier to an authorised service centre for testing.
Do not overdrive the amplfier, 40W is the absolute maximum input power required
only on 160 and 6m. All other bands require a maximum of 20W to realise full
output power.
In operation the exhaust area of the heatsink
g
will become hot, do not touch this
area during or immediately after operating the amplifier.
