In addition, since the PLC uses the power line, it is necessary to match the phases of L1 and L2 so
that it can communicate using the same line on the 100 V line.
If the phases are different, PLC communication will be performed using different lines, which may
cause the PLC signal to attenuate, slow the communication speed, or cause communication to
become impossible.
These are examples using Japanese power line and distribution board.
1) If the PLC adaptor can be placed in the same circuit, the best condition for signal attenuation will
be better.
2) When arranging the PLC adaptors across multiple circuits,
Please attach a PLC adaptor for multihop relay in the vicinity of the distribution board.
3) 3) Even if a PLC adaptor for multi-hop relay attachment is installed near the distribution board,
but the speed is not enough, please make a separate PLC network for each circuit and bridge
with an Ethernet cable at the distribution board.
