7548/7794/7796/7796HC OPERATOR’S MANUAL – SECTION 2
Connect your input signal to the amplifier’s unbal
-
anced or balanced input connector as shown in
Figure 2.4.
Use cables that are high quality and
shielded to minimize noise and to guard against
possible feedback.
Figure 2.5 – 208V 3-Phase AC Mains Wiring
The amplifier includes a NEMA style locking AC
connector as standard equipment. Connect the
amplifier to the proper 3-phase AC mains with this
connector. See
Figures 2.5 and 2.6
for proper AC
Mains wiring. The connector then plugs into the
amplifier.
2.7 Start-up Procedure
1.
Turn down the level of your signal source.
2.
Check to make sure the AC Mains Switch/
Circuit Breaker is in the off position
(DOWN).
3.
Apply AC power to the amplifier.
4.
Move the AC Mains Switch/Circuit Breaker
to the on position (UP) to turn the amplifier
ON. Wait for the amber READY and green
RUN LEDs to illuminate.
5.
Adjust the level of your input signal source
to achieve the desired output level.
6.
Use the Navigation Buttons to navigate
through the various voltage and current
measurement functions on the LCD dis
-
play.

The risk of lethal ELECTRICAL SHOCK
exists when connecting AC mains! Dis-
connect the source before connecting
AC power wires to the connector.
DANGER
2.6 Connecting the AC Supply
The 7548/7794/7796/7796HC amplifier requires
3-phase wiring. Always operate the amplifier from
proper AC mains. The 3-phase, 47 - 60 Hz voltage
must be 208 VAC (or optionally 400 VAC, except
model 7796HC) with no more than 10% variance
above or below the line voltage. The amplifier will
not operate properly outside these limits.
