5.3 Rear Panel Controls
The locations of the rear panel controls are shown in Figure 5-1. The function of the 115V/230V
switch and power cord receptacle were covered in section 2-3. It is important to connect the
load in accordance with the L (line) and N (neutral) indications on the rear panel for maximum
safety and accuracy. Refer to section 5-4.

5.4 Making Connections
The 2105 is designed to accommodate a multitude of connection methods allowing the user or
test engineer to design custom harnesses according to the application. The basic guidelines for
making connections are:
1)
The supply voltage is connected between the "L" and "N" terminals (line and neutral).
2)
The current to the load passes through the internal shunt. The load is connected to the
right-hand
In effect, the Power Analyzer is placed in series with the load to monitor the power drawn by it.
Some connection methods are more complex and require some explaining. These are
described in the following paragraphs.
CAUTION!
Lethal voltages are routinely connected to the terminals of the 2105. Make sure that power
sources are disabled before making or removing connections.
