2 System Setup
2.1 Safety First
Throughout these instructions, special emphasis
is placed on good safety practices. The following
graphics are used to highlight certain topics that
require extra precaution.
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.
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.
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.
2.2 Unpacking and Installing
Your system will be delivered to the ship-to ad-
dress enclosed in a wooden crate and transported
on a special, shock-absorbing pallet. With the addi-
tion of packaging, the cabinet can weigh from 450
pounds (7810 Series) to more than 950 pounds
(7820 Series). (Or from 204 kg to more than 430
kg). To avoid serious injury and/or product dam-
age, use a heavy-duty lift or other suitable equip-
ment to unpack and move the product to its place
of installation.
To uncrate the product, remove the top and one
side of the crate, then use a lift or other suitable
equipment to glide the cabinet from the crate and
off the pallet. Cable lift rings are installed at the
cabinet top corners of the heaviest cabinets to
facilitate product removal (see Figure 2.1).

WARNING
Never attempt to lift the cabinet without
assistance. Crushing bodily injury can
result if care is not taken during instal-
lation. Cabinets may overturn if not
secured.
The cabinet has been tested and inspected for
damage before leaving the factory. Carefully un-
pack and inspect the product for damage. Please
note any damage for future reference and
notify the shipping company immediately if
damage is found. Also, please save the shipping
crate and pallet as evidence of damage and/or for
returning the cabinet for repair.

2.3 Check Contents
In addition to the 7800 Series cabinet, your ship-
ment should include the following:
1. Quick Start Guide
2. 7800 Series Operation Manual on USB drive
2.4 7800 Series Cabinet Location
7800 Series cabinets are mounted on wheels to
allow rolling on a flat, smooth surface. To avoid
possible tipping, always push the cabinet from the
front and avoid rough or pitted surfaces.
Locate your cabinet near a three-phase power
source. Allow enough clearance at the front and
back of the cabinet to allow adequate airflow and
hot air discharge through the cabinet rear. See
Figure 2.2 for clearance recommendations
2.5 Connections and Startup
This section details the wiring and startup pro-
cedures for a 7800 series amplifier operating in
Controlled-Voltage mode (factory default). Before
connecting the amplifier inputs and outputs, make
sure the AC power is disconnected.
