CAUTION!
If the core processor is mounted integrally with the sensor, twisting the core processor will
damage the sensor. To avoid damaging the sensor, do not twist the core processor.
CAUTION!
Damaging the RS-485 wires can cause measurement error or meter failure. Damaging the
power supply wires can cause meter failure. When replacing the core processor cover, make
sure that the wires are not caught or pinched.
