Panasonic MKG1500-DE Serie Installationsanleitung Seite 15

Pass the CT cable through from the measuring unit until sufficient space is available for installation of the
main breaker CT.
Connect the CT to the three separate side of the CT cable.
Install the CT on the power wire as per the number of current phases stated on the CT cable.
Ensure that there is no branch wire between the CT
measurement point and the power grid, otherwise
accurate energy measurement will not be possible.
The CT cannot provide accurate measurements if the
current phase installation positions differ.
The CT has a polarity. When installing the
power wire to the CT, ensure you follow the
labelling on the CT.
Use CT where the wire temperature is
below 50 ℃.
Connect the other side of CT cable connector to the CT connector on
top of the measuring unit labelled MAIN, after removing the cover.
Leave the other covers as they are.
Checking Installation
1
Are the phases on the power connection breaker side of power terminal connection wires correct? (Step
2
Are the measuring unit of power terminal wires on the correct phase and fully inserted? (Step
3
Is the CT installed location and direction correct? (Steps
4
Are the CT and CT cable installed in the correct position? (Step
5
Turn the power connection breaker and main breaker ON, and check the measuring unit POWER LED (green)
lights up.
( ERROR LED lights up once when powers ON )
For single-phase 2 wire
For a single-phase 2 wire system, the installation process is similar to that for the 3-phase 4 wire system, but the
connection of the power and the CT differs.
Power supply connection: Connect the power wire from the single-phase 2 wire power connection breaker to the
V1-VN terminal on the measuring unit.
CT connection: Use only I1 on the CT and do not connect the other CT.
Unused CTs may be used for solar PV or a storage battery on a single phase system by purchasing a CT cable
(MKG1530-DE , Optional item).
