SECTION II
INSTALLATION
2-1. INTRODUCTION
This section contains information for the installation of the -hp- Model 35601A into the -hp-
3047A Spectrum Analyzer System. Also included in this section is a discussion of the instru­
ment's power requirements and repackaging information. Since the -hp- 3047A is supplied
with the -hp- 35601A installed, this section is provided only for reference in case the -hp-
35601A has been removed for service. However, as a precaution, make sure the correct line
voltage selection has been made before applying power to the instrument.
2-2. POWER REQUIREMENTS
Before applying ac-line power to the -hp- 35601 A, be sure that the
VOLTAGE SELECTOR switches are set for the proper line
voltage and the correct line fuse is installed in the rear panel FUSE
holder.
2-3. Line Voltage and Frequency
The -hp- 35601A requires a single phase power source of:
86 V to 127 V (48Hz to 66Hz), or
189 V to 225 V (48Hz to 66Hz)
2-4. Grounding Requirements
To protect operating personnel, the instrument's panel and cabinet must be grounded. The
-hp- 35601A is equipped with a three-wire power cord which, when plugged into an ap­
propriate receptacle, grounds the instrument. The offset pin on the power plug is the ground
connection.
WARNING
/. The power cable plug must be inserted into a socket outlet pro-
vided with a protective earth contact. The protection of the
grounded instrument cabinet must not be negated by the use of an
extension cord without a protective conductor.
2. If this instrument is to be energized via an auto-transformer to
reduce or increase the line voltage, make sure that the common ter-
minal is connected to the Earth pole of the power source.
