The current transformer terminal block is located at the top rear of the chassis. The
IQ 310 and the IQ 320 each have 6 terminals, grouped in 3 pairs: one pair for each
phase current transformer, see Figure 2.4a and 2.4b.
The IQ 330 has twelve terminals, grouped into six pairs: one pair for each phase
current transformer, as shown below, and one pair for each of the two digital inputs
and the one analog input.
Note:
For sections 2.3.1 through 2.3.4 refer to figures 2.4c, 2.4d and 2.4e.
2.3.1
Current and Voltage Inputs
The voltage terminal block is located at the bottom rear of the chassis. It has four
terminals for wiring the phase voltages and the neutral, as shown in Figure 2.5. The
neutral terminal
must
be connected to system neutral or ground depending on
system configuration. All connections must be made in accordance with national
and local requirements and codes.
