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 below. 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.
Phase Voltage Terminal
A VA
B VB
C VC
Neutral NEU
The current transformer terminal block is located at the top rear of the chassis. It
has six terminals, grouped into three pairs: one pair for each phase current
transformer, as shown below.
Phase CT Terminal Pair
A H1A, H2A
B H1B, H2B
C H1C, H2C
2.3.2 Power Supply Input
The IQ 200 power supply input is connected to the PS1 and PS2 terminals on the
lower right rear of the Base Module chassis. The IQ 200 requires 90 to 600 VAC or
48 to 250 VDC, and may be wired directly to the monitored system if the voltage is
within range.
2.3.3 Local Display Connection
The supplied
Category 5 cable
connects to the
DISPLAY
port located on the middle
right rear of the chassis and to the port on the IQ 200 Display Module. Do not route
the Category 5 cable in the same enclosure or cable tray as 600V system wiring.
2.3.4 INCOM™ Communications
The IQ 200 Electrical Distribution System Meter is an IMPACC (Integrated
Monitoring, Protection, And Control Communications) compatible device. As such, it
can be remotely monitored and functionally modified.
IMPACC is a noise-immune communications system that permits communication to
and from a master computer and the IQ 200 or other devices using a high frequency
carrier signal transmitted over a properly terminated, shielded twisted pair cable.
