Amplifier Unpacking and
Installation
The 8302 amplifier is a precision instrument that
can be dangerous if not handled properly. Lethal
voltages are present in both the AC input supply
and the output of the amplifier. For this reason,
safety should be your primary concern when you
setup and operate this amplifier.
2.1 Safety First
Throughout this manual special emphasis is
placed on good safety practices. The following
graphics are used to highlight certain topics that
require extra precaution.
2.3 Installation
The 8302 amplifiers are packaged in a rugged
powder-coated chassis. This chassis is 3U (rack
units) tall, and has rack “ears” on each side of the
front panel for mounting to a standard EIA (Elec
-
tronic Industries Association) rack. Use standard
rack mounting hardware to mount the ampli
-
fier. Use nylon washers if you wish to protect the
powder-coat finish on the front of the amplifier.
Optionally, the amplifier can be placed on a
bench top; please keep in mind that the protective
powder-coating can be scratched when placed
on other equipment or on a bench top, especially
when there is dirt present. To protect the finish, a
set of rubber feet is included in the toolkit that can
be installed on the bottom of the amplifier.
Allow ample space on the sides and especially
the back of the amplifier for heated air to escape.
The amplifier should be mounted in a rack that is
adequately ventilated and not sealed. Likewise,
the front of the amplifier should be unobstructed to
allow cool air to enter the amplifier.
WARNING alerts you to hazards that
could result in severe injury or death.
Note the explanation of the hazard and
the instructions for avoiding it.
WARNING
CAUTION indicates hazards that could
result in potential injury or equipment
or property damage. Once again, note
the explanation of the hazard and the
instructions for avoiding it.
CAUTION
Do not operate the amplifier in a small
sealed chamber of any kind. Improper
operations and overheating will result.
CAUTION
2.2
Unpacking
All amplifiers are tested and inspected for dam
-
age before leaving the factory. Carefully unpack
and inspect the amplifier for damage.
Please note
any damage for future reference and notify the
shipping company immediately if damage is
found.
Also, please save the shipping carton and
materials as evidence of damage and/or for return
-
ing the amplifier for repair.

the amplifier inputs and outputs, make sure the AC
power is disconnected.
Testing Before Controlled-Current Operation
IMPORTANT:
If your application requires Con
