In case of failure, return the Mainframe or Load module to Sorensen sales or service
office for repair.
2.5 Application Connection
2.5.1 Load Connections
WARNING!
To satisfy safety requirements, load wires must be heavy enough not to overheat
while carrying the short-circuit output current of the device connected to the
electronic Load.
Before connecting load wires to Load module, remove the terminal cover from the Load.
Install it after load wires are connected. Input connections are made to the
+
and
−
terminal block on the front of each Load module. The major considerations in making
input connections are the wire size, length and polarity. The minimum wire size
required to prevent overheating may not be enough to maintain good regulation. The
wires should be large enough to limit the voltage drop to no more than 0.5V per lead.
The wires should be as short as possible, and bundled or tied together to minimize
inductance and noise picked up from them. Connect the wire from the PLUS (
+
)
terminal on the module to the HIGH potential output terminal of the power supply (UUT).
Connect the wire from the MINUS (
−
) terminal on the module to the LOW potential
output terminal of the power supply (UUT). Figure 2-5 illustrates the typical setup for
the Load module to the UUT.
WARNING!
To prevent accidental contact with hazardous voltage, cover of terminal must be
installed correctly. Each terminal can carry 40 Amps at most. If input current
of Load is over 40 Amps, you must use multiple terminals of connections.
