1.4 INSTALLATION
Before proceeding, thoroughly inspect the amplifier for signs of physical damage that may have been incurred
during shipment and completely read the following installation and operating instructions, paying special
attention to all CAUTION notes.
1.4.1 Location
Select an operating location that will permit air to circulate freely around the amplifier’s cabinet. The
Model 500A250D utilizes air cooling and should be located where the normal flow of air into or exiting from
the unit will not be restricted, diverted, or re-circulated through the unit itself; in particular, the flow of warm
air exiting the rear of the amplifier should not be impeded.
Do not position the unit next to a wall or other equipment that would restrict the flow of air into the bottom of
the unit or out of the rear of the unit.
1.4.2 Main Power
The Model 500A250D is designed to operate using AC primary power of 200–240 Volts Alternating Current
(VAC), 50–60 Hz, single phase, 2400 watts maximum.
CAUTION:
Dangerous voltages are present in the Model 500A250D whenever the unit
is plugged into an AC outlet. Always disconnect the unit from the main
power line when servicing it.
1.5 RF CONNECTIONS
