Phase B (V2 & I2) is denoted by the yellow color; and Phase C (V3 & I3) is denoted by
the blue color. An optional fourth output module is denoted by the black color box. With a
fourth output module installed, there may be up to four phases of voltage and current, or
two three phase open delta voltages, with four currents, or up to eight phases of current.
The first four phases are indicated by V1/I1, V2/I2, V3/I3 and V4/I4. Once the voltage
generators are converted to current generators, they will change as indicated below:
V1
⇒
I5
V2
⇒
I6
V3
⇒
I7
V4
⇒
I8

Incoming Power / Line Cord
– the input line cord, ground terminal, are mounted on the
back panel of the test set.
Input Line Cord
The test set is equipped with a line cord; see the accessory kit, which
connects to the male plug on the back panel. Verify the input voltage
before connecting the line cord to the power source.
NOTE:
The unit can be powered from an input source with a rating of
100 VAC to 240 VAC. The unit automatically adjusts to the available
power if it is within the specified range.

Earth Ground Jack
– use this terminal to connect chassis ground to earth ground.
A chassis ground (earth) point on the back panel is provided as an
additional safety ground.
