SECTION 2

Amplifier Unpacking and
Installation
The 7224/7226 amplifiers are precision instru
-
ments that can be dangerous if not handled prop
-
erly. Lethal voltages are present in both the AC
input supply and the output of these amplifiers. 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.
Along with any additional accessories purchased
by the customer, all 7224/7226 amplifiers ship with
the following:
• 7224 or 7226 Amplifier
•
Toolkit (contains one #2 Phillips screwdriver
and four rubber feet)
• Power Cord
• Operator’s Manual and Quick Start sheet
2.3 Installation
The 7224/7226 amplifiers are packaged in a
rugged powder-coated aluminum chassis. This
chassis is 2U (rack units) tall, and has rack “ears”
on each side of the front panel for mounting to a
standard EIA (Electronic Industries Association)
rack. Use standard rack mounting hardware to
mount the amplifier. 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.
DANGER represents the most severe
hazard alert. Extreme bodily harm or
death will occur if these guidelines are
not followed. Note the explanation of the
hazard and instruction for avoiding it.

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.
