Model 800A3B
Rev D 3
1.5.1 Location
Select an operating location that will permit free air circulation around the amplifier’s cabinet. The Model
800A3B 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. For example, do not position the unit
next to a wall or other equipment that would cause a restriction of airflow into or out of the unit.
CAUTION:
Under normal operating conditions, the exhaust air temperature may
exceed 40
°
C. Do not locate heat sensitive equipment, objects or materials
in the exhaust air stream of the unit.
1.5.2 AC Power
The Model 800A3B is designed for a primary power input of 190-240 VAC, 50/60 Hz, single phase.
CAUTION:
Dangerous voltages are present in the amplifier whenever it is plugged
into an AC outlet. Always disconnect the AC power line to the amplifier
before servicing the unit.
1.6 CONNECTORS
1.6.1 Amplifier Input Connector
The RF input connector for the amplifier is located on the left side of the control panel. It is a female, Type N
connector.
1.6.2 Amplifier Output Connector
The amplifier RF output connector is a female Type N located on the right side of the control panel.
CAUTION:
Placing the amplifier in the operate mode without a load connected to the
output connector is not recommended.
1.6.3 Safety Interlock Connector
Located on the left side of the rear panel, as viewed from the rear, are the remote interface connectors and
safety interlock connectors. The 15-pin D-sub miniature female safety interlock connector provides two
separate interlock loops. Pins 1 and 8 are used for situations where the amplifier can be left on, but forced into
STANDBY mode. This interlock is called Inhibit Interlock. Pins 10 and 14 are used for situations that
demand the safest possible condition, with the AC power to all main circuits disconnected. This interlock is
called AC Interlock. Both loops must be closed, or jumpered, for normal operation.
