3 Connections and Startup
This section details the wiring and startup proce
-
dures for a single 7224 or7226 amplifier operat
-
ing in Controlled-Voltage mode (factory default).
Before connecting the amplifier, make sure the AC
power cord is unplugged.
3.1 Other Operation Modes and
Configurations
The 7224/7226 amplifier can be field-configured
for operation in a number of ways. The ampli-
fier can be operated in Controlled-Voltage or
Controlled-Current mode. It also can be configured
for operation as a part of a multi-amplifier system.
These alternate configurations may require special
output wiring and/or additional components.
3.1.1 Controlled-Current Operation of a
Stand-Alone Amplifier
If your application requires Controlled Current
operation, the amplifier first should be wired and
tested in Controlled-Voltage mode to verify that the
amplifier and input signal are operating correctly.
Once proper operation is confirmed, refer to the
“
Applications”
section of this manual for instruc-
tions on configuring and operating your amplifier in
Controlled-Current mode.
3.1.2 Multi-Amp Operation
If your application requires multi-amp operation for
increased voltage or current, each amplifier should
first be wired and tested individually in Controlled-
Voltage mode to ensure proper operation.
To configure two or more amplifiers for
Series or
Parallel operation in Controlled-Voltage mode,
refer to the
Multi-Amp Configuration Guide
(available for download from aetechron.com).
For
Series or Parallel operation in Controlled-
Voltage mode,
refer to the
“Applications”
section
of this manual.
For
Series operation in Controlled-Current
mode,
you should select one amplifier to be oper
-
ated as the “Master” amplifier of the system, and
then refer to the
“Applications”
section of this
manual for instructions on configuring this ampli
-
fier for operation in Controlled-Current mode. After
the Master amplifier is configured and tested for
Controlled-Current operation, refer to the
Multi-
Amp Configuration Guide
(available for down
-
load from aetechron.com) for information on Series
system configuration.
For
Parallel operation in Controlled-Current
mode,
please contact
AE Techron Technical
Support
for assistance.
3.2 Connecting the Load
3.2.1
Preparation and Cautions
Before connecting the amplifier, make sure the
AC power is disconnected.
Always use the appropriate wire size and insula
-
tion for the maximum current and voltage expected
at the output. Never connect the output of the
Figure 3.1 – 7224/7226 Back Panel
ELECTRIC SHOCK HAZARD.
Output potentials can be lethal. Make
connections only with AC Power OFF
and input signals removed.
