Installation / Setup
The installation/setup highlights for the Hewlett-Packard 3776B PCM Terminal Test Set include the following key points:
1. If the instrument is to be energized via an auto-transformer, ensure the common terminal is connected to the neutral pole of the power source.
2. Use only the provided mains cable for the instrument. If unsuitable, contact the nearest HP service office.
3. The mains plug should be inserted into a socket outlet with a protective earth contact, and the protective action should not be negated by using an extension cord without a grounding conductor.
4. Before switching on the instrument, check that:
a. The input voltage selector matches the power source voltage.
b. All connected devices are grounded.
c. The line power plug is connected to a three-conductor outlet with a protective ground.
d. The instrument fuse is of the correct type and rating.
5. Servicing should be performed by qualified personnel, and any maintenance under voltage should be avoided unless necessary and performed by skilled individuals aware of the hazards.
6. Capacitors may remain charged even if the instrument is disconnected from the power source.
7. If protection is impaired, the instrument must be made inoperative and secured against unintended operation.
