must go to terminal “N1”. The actual arrangement of the CT connections depends on the
installation configuration.
6. Repeat items 4 and 5 (above) for each CT until all CTs have been installed and
connected to the MCI screw terminals.
7. Step 4 is complete if the shorting links are in place, the power can now be turned on.
However, if you are installing the meter head immediately, leave the power off until the
meter head has been installed.
Step 5: Install equipment and covers
It is much better to do this step with the power off. However, if it is not possible to turn the
power off, this step can be done with power on. If power is on and meter head is unplugged,
SHORTING LINKS MUST BE IN PLACE.
1. Plug the 4 Current connectors, labeled CT1, CT2, CT3, and CT4 into the corresponding
connectors in the back of the meter head. The connectors are color-coded and polarized.
Make sure that the color of the plugs matches the color of the connectors on the meter
head. There are 2 connectors of each color, but they will only plug in one way because
one of the connectors has male pins, and the other has female pins. If a connector does
not mate easily, try the other same-colored connector.
2. If the optional Communications Module is installed, there will be a 4-pin connector on the
end of a wire coming out of the MC-5c meter head. Plug this connector into its mate
connector which is on the end of a wire that goes into the Communications Module
housing.
3. Plug the voltage connector from the fuse block (see figure 3-1) into the back of the
meter head.
4. Make certain that the current connectors voltage connectors and ribbon cable on the
meter head are all plugged in securely and correctly.
5. Remove the shorting links from the MCI.
6. Close cover and secure with provided screw.
7. If power was off, turn it on.
8. Installation is complete. The LCD on the MC-5c meter head should be displaying letters
and numbers. The meter is ready for testing and certification.
CAUTION:
When reading the meter display, all consumption and demand values must be multiplied by
the correct multiplier to calculate true value.
Please refer to Chapter 6: Applying Multipliers.
