Chapter 4:
Electrical Installation IQ 250/260 Meter
CT Leads Terminated to Meter
The IQ 250/260 is designed to have Current Inputs wired in one of three ways. Diagram 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.
Other current connections are shown in Figures 4.2 and 4.3. Voltage and RS485/KYZ Connection is shown in
Figure 4.4.
Wiring Diagrams are shown later in this chapter.
Communications Connections are detailed in Chapter 5.
