Turn-On Self-Test; Application Connection; Load Connections - Chroma 63200A Series Operation & Programming Manual

when you connect the power cord to correct line voltage and turn on the Electronic Load.
Line fuses do not need to be changed when the line voltage is changed.
The line fuses will protect the Electronic Load from incorrect voltage
setting.

Turn-On Self-Test

Check the following before turning on the Load.
1. The nominal line voltage of the AC input socket is in the range of 100-240 Vac.
2. The power cord is connected to the AC input socket.
WARNING
The power cord supplies a chassis ground through a third connector.
Be sure that your outlet is of three-conductor type with the correct pin
connected to ground.
Power on the Load by the front panel switch and observe the display. Immediately after
turning on, the Electronic Load executes a self-test that checks firmware and communication.
The Load Module displays the model no. and firmware version.

Application Connection

2.4.1

Load Connections

Input connections are made to the  and  terminal connectors on the rear panel of each
load. The major considerations for input connections are the wire size, length and polarity.
The minimum wire size required to avoid overheating may not be enough to maintain good
regulation. The wires should be large enough to limit the voltage drop. The wires should be
as short as possible, and bundled or tied together to minimize inductance and noise.
Connect the wire from the PLUS () terminal to the HIGH potential output terminal of the
power supply (UUT) and the MINUS () terminal the LOW potential output terminal of the
power supply (UUT). Figure 2-2 illustrates the typical setup of the Electronic Load to the
UUT.
