Checking the connection of the
Power Measuring Unit to the Gateway.
IMPORTANT
(1) Remove the cover and pass the CT Cable and connect it to the CT connector on the
Power Measuring Unit labelled "PV" for measurement of a solar generation system
or the connector labelled "SB" for measurement of a storage battery system.
(2) Check the phase of the breaker connected to the solar generation or storage
battery system being measured, and connect and install the CT to I1, I2 and I3 on
the CT Cable so that they connect to V1, V2 and V3 on the power wire.
* To attach multiple solar PV or storage battery systems, the position of the clamp
Note
should be where the systems share a wire. If such a connection site is not
available, only a single system can be measured. Additionally, measurement will
not be possible if the rating is exceeded (63A).
* When adding a cable for a solar generation or storage battery system to an
existing system, ensure that the main breaker or dedicated power connection
breaker is "OFF" prior to commencing work.
1. Are the phases on the power terminal connection wires correct?
2. Are power terminal wires on the correct position and fully inserted?
3. Is the CT installation position and direction correct?
4. Is the CT Cable installed in the correct location?
5. Turn the dedicated power connection breaker and main breaker on,
and check the Power Measuring Unit power LED lights up.
Once checks are complete, tap the "Next" button.
