No magnetic-field sensitive devices should be located next to the right side of the amplifier
as its power transformer is located there. It's best to position it to the right of your
transceiver. No temperature sensitive devices should be located above the exhaust hot air
area, so don't push it under a shelf. You may prefer to use the bottom scales of both variable
capacitor knobs (TUNE and LOAD) if you install it on a shelf. DO NOT OBSTRUCT AIR INTAKE
(rear panel) and EXHAUST (top cover) areas of the amplifier. Keep a minimum distance of
10cm (4 inches) to the intake and 50cm (20 inches) to the exhaust openings.
2-4. Connections
Connection to your station must be accomplished in the order described below, before
you apply mains voltage to the amplifier.

Note that the grounding system may have to withstand currents over 20A
with insignificant voltage drop on it. Therefore, it may be necessary to
improve it considerably, i.e. to become less resistive, with heavier leads
and lower-resistive ground path. The grounding leads should be at least
8mm2(AWG 8 or SWG 10).
Fig.2-1 Connections
a)
First, connect the ground stud of the amplifier (on the rear panel, marked GND) to
the station's grounding system (Fig.2-1).
b)
Connect a coaxial cable with a PL-259 plug from the transceiver output to the amplifier
rear panel RF INPUT socket.

If this is the first time you will use a power amplifier in your station, pay attention
to the coaxial cable type from the amplifier's three outputs. The cable must
handle the increased power safely, particularly on the 10 and 6 m bands. We
recommend that you use RG213 or better. Check the same for the antenna
selector and tuner as well as the antenna itself (especially multi-band trap
antennas).
