Connections And Startup; Other Operation Modes And Configurations; Connecting The Load - AE Techron 2105 Operator's Manual

3 Connections and Startup

This section details the wiring and startup pro-
cedures for a single 2105 amplifier operating in
Controlled-Voltage mode (factory default). Before
connecting the amplifier, make sure the AC power
cord is unplugged.
ELECTRIC SHOCK HAZARD.
Output potentials can be lethal. Make
connections only with AC Power OFF
and input signals removed.
3.1 Other Operation Modes and
Configurations
The 2105 amplifier can be field-configured for
operation in a number of different ways. These
would include Controlled-Voltage or Controlled-
Current mode, and 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 2105 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 instructions 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.
For Series operation in Controlled-Voltage
mode, refer to the Multi-Amp Configuration
Guide (available for download from aetechron.
com) for information on Series system configura-
tion.

WARNING
Information subject to change
2105 OPERATOR'S MANUAL – SECTION 3
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-Voltage
mode, refer to the Multi-Amp Configuration
Guide (available for download from aetechron.com)
for information on Parallel system configuration.
For Parallel operation in Controlled-Current
mode, please contact AE Techron Technical
Support for assistance.

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
amplifier to any other model amplifier, power sup-
ply, signal source, or other inappropriate load; fire
can result.
NOTE: The 2105 amplifier comes with a factory-
installed 2.7-ohm, 2W, 5%, metal-oxide resis-
tor connecting the terminals marked "COM and
"CHASSIS GROUND" (see Figure 3.1). This
resistor should NOT be removed except when the
amplifier is being used as a Slave amplifier in a
Series multi-amp system. WARNING: Removing
this resistor can cause dangerous output and/
or damage to the load.
3.2.2 Connecting the Outputs
Connection to the output of the amplifier is to a
3-position terminal strip with #8 screws. Wires
