STEP 3 - INSTALLING AND CONNECTING THE CT’S
A) CAUTION – IF THIS IS A COMBINATION PANEL, THE LUGS ON THE PRIMARY
SIDE OF THE MAIN BREAKER ARE PROBABLY STILL HOT. The CT’s must be
installed with the red polarity dots either both facing towards the main breaker, or both
away from the main breaker to maintain the correct polarity. If both CT’s are not in-
stalled in this manner, the readings will be wrong.
• Note: Do not install the CT over the neutral (N) (grounded) conductor.
B) Install one of the Current Transformers (CT’s) over each incoming power line Phase
A or B, by pressing on the handle to open the split core CT and
then clipping it over the power lines as shown in
Fig 3. Preferably, they should be installed on the
secondary side of the main switch or main circuit
breaker, however if this is not possible, such as in the case of a com-
bination breaker panel, then install on the primary side of the main breaker.
• Insure that the 2 sides of the split core CT’s are mated tightly together
C) Connect the CT’s to the MTU by plugging the plastic mating connectors together.
• Note: The connectors are polarized and can only be inserted one way. Do not force.
D) Arrange and tie-wrap all wiring in a neat and tidy manner.
E) Turn the power back on.
F) Conrm that the green LED on the MTU is ashing approximately
once-per-second. If not, check MTU installation or refer to Trouble-
shooting Section in Appendix B.
STEP 4 - SETTING THE HOUSE CODE
NOTE: TED’s display unit can possibly receive data from other TED MTU’s con-
nected to the secondary side of the same utility transformer. To guard
against reading your neighbor’s electricity use, each MTU has a House
Code from 000 to 255. This number can be found in two places: on a sticker
on the MTU, and on a sticker included loose with the MTU. Place this
sticker on the outside of the panel for future reference. The House Code is
the three-digit number preceding the Serial Number. In the example below
the House Code is 137.
TO SET THE HOUSE CODE:
The RDU has 4 buttons on the front
labeled $, u, p, and “MODE”.
