2.2 Basic Connection Setup
Figure 1 shows the basic connections of the OMU1-S-RF with the external equipment. The OMU1-S-RF
is powered by an internal switch-mode power supply (SMPS) module and is not powered through the
USB cable. The USB connection only provides the communications link between the host PC and the
OMU1-S-RF.
The OMU1-S-RF has two NEMA connectors, one male and one female. The male connector is for inlet
and the female connector is for outlet. The male connector is connected to a wall outlet or a power strip.
The female connector connects to the load to be measured.
