Current Sensor Wiring
Once all the current sensors are installed on their appropriate phase conductors,
you can begin terminating the current sensors on to the Class 1000 main power
board.
The current sensor leads can be extended up to 2,000 feet (using #14-22 AWG
wire) for remote monitoring applications. Consult your local electrical codes for
proper wire sizing (#22 AWG twisted pair wire with a black and white conductor,
rated for 600 VAC recommended.)
The current sensor connection points are located on the bottom center of the
main power board. If supplied with the terminal block (TB1) (standard confi gura-
tion), the current sensors are connected to the 6 positions on the right side.
If your meter is equipped with removable current sensor terminal blocks (MI
confi guration), you can fi nd the current censor connection points located on the
bottom center of the main power board. Three removable plugs exist, one for
each current sensor phase input. The header portions of the connectors are
labeled TB2, TB3 and TB4. Text silkscreened on each of the connectors instruct
you which terminal of the plug is for the white conductor and which terminal is
wired to the black conductor. Once each current sensor is wired to its respective
plug, insert each plug into the appropriate header.
