Prepare the GT-1000A for Use
2.5.1
Cooling
The GT-1000A has an internal cooling fan. The air intake is located on the rear panel of the instrument. When
using the GT-1000A, ensure there are no obstructions to the flow of air into the instrument.
2.5.2
AC Power Requirements
Fuse Specifications:
see Table 13 on page 15.
PROTECTIVE EARTH GROUND
This is a Safety Class 1 product (it includes a protective earth terminal). An
uninterruptible safety earth ground must be provided from the main AC power
source to the GT-1000A’s AC input connector. Observe the following:
If it is possible that the safety earth ground has been impaired, make the
GT-1000A inoperative and secure it against unintended operation.
If the GT-1000A will be powered through an autotransformer, verify that
the autotransformer’s common terminal is connected to the neutral
connector (the grounded side of the Mains supply).
MATCH FUSE TO INPUT AC VOLTAGE
Before applying AC power to the GT-1000A, check that the fuse in the rear of
the instrument (see Replace the Fuse on page 7) has a voltage rating that
matches the AC voltage.
AC Line Cord:
All GT-1000A microwave synthesizers are supplied with a 6-foot, three-wire power cord with
three-terminal polarized plug with a safety ground. If a different power cord is used, it must not exceed 3 meters
(9 feet) in order to meet safety requirements.
Table 5 below describes the AC power requirements for the GT-1000A.
