INSTALLATION NOTES
Applicable for the following catalog numbers
¹
:
MC5c240V 24R1 (1EL/24M 240V 1P3W)
= "L" for 0.1 Amp inputs or "H" for CL10 (5 Amp) inputs.
¹
Also applicable when the same meter model number has the suffix: M, RS or P.
CRITICAL: The line association and polarity of the current transformers must be followed or meter will not be
installed correctly.
CTs must be all 0.1A or 5A and cannot be mixed on the same meterhead.
1. Each CT has a white side, small white dot, or "H1" marking on only one side of its exterior moulding. Locate
this marking since it is critical that the wires are passed through the CT in the correct direction, assuring the
correct polarity.
Two wires coming from the line side are passed through each CT.
Line 1 (Wire 1): Line 1 should be passed though the CT from the side with the white side, dot, or H1 marking.
Line 2 (Wire 2): Line 2 should be passed through the CT from the side WITHOUT the white side, dot, or H1
marking. Note that these are opposite polarities.
2. The MCI runs CT terminals CT#1 to CT#24 with each terminal connected to Meter #1 (M#1) to Meter #24
(M#24). The number of CT terminal and meter connections will depend on the number of suites available. For
example:
-M#1 connects to CT#1
-M#2 connects to CT#2
-repeat for M#3 to M#24
3. After completing all CT terminations, connect the four (4) current connectors from the MCI board to the
meterhead and then remove shorting links for all meter points that are in use.
4. Follow local codes for installation requirement, e.g. conduit, fused disconnect, distance, and wiring.
5. Installation of 0.1A ("L") inputs and CL10 or 5A ("H") inputs are the same.
CAUTION: If breakers are energized, shorting links must be installed before:
a) disconnecting the CT headers or
b) replacing or installing meter heads on the panel.
WARNING: Bodily injury or damage may result if shorting links are not installed.
