4.2: CT Leads Terminated to Meter
The Shark® 100/50 meter is designed to have current inputs wired in one of three
ways. Figure 4.1 shows the most typical connection where CT Leads are terminated to
the meter at the current gills. This connection uses nickel-plated brass studs (current
gills) with screws at each end. This connection allows the CT wires to be terminated
using either an “O” or a “U” lug. Tighten the screws with a #2 Phillips screwdriver. The
maximum installation torque is 1 Newton-Meter.
Other current connections are shown in Figures 4.2 and 4.3. Voltage and RS485/KYZ
Connection is shown in Figure 4.4.
