Preparing Your Station
Use new, clean connectors and install them according to manufacturer
recommendations. Clean the connectors after soldering them and before
mating them with the amplifier.

NOTE: The FCC requires users to check their installations for
compliance with published values for allowable exposure to RF fields.

and on the web. We strongly recommend that you do this for any
installation, both fixed and at an expedition or contest site.

Provide surge protection.
Induced energy from nearby electrical storms or other power transients
may damage components. Such damage is not covered under warranty. It
is therefore important to use a good lightning arrestor. However the only
lightning-proof solution available is to disconnect antenna feedlines and
AC power when the equipment is not in use.

NOTE: Whenever the amplifier is online — either off, in standby
(STBY), or in warm-up with the WAIT LED lighted — the amplifier is
bypassed and the exciter is connected directly to the antenna. The
throughput limit in all cases is 1500 W.

3.2 Limitations of Operation at 90–130 VAC
Electrical-power equipment draws twice as much primary current from
120 V mains as from 240-V mains. Therefore, if you operate the Alpha
9500 on typical 120 V/20 A household circuit without exceeding the 20-
A circuit rating, you limit maximum peak power output to about
600–1000 W.
