WARNING
The connectors used in this function have protective covers. When the covers are
removed or when using connectors, the voltage ratings across the measuring input
and the ground become as follows:
Voltage across A,
±
(V and A side) input terminals and ground 400 Vrms max.
Voltage across V terminal and ground 600 Vrms max.
Put the protective cover on the connector when this function is not used.
