(a) Input voltage can not be higher than the rated input voltage (100V or 380V)
of the product, or PT shall be considered to be used. For ease of maintenance,
we recommend to use the terminal block.
(b) Input current can not be higher than the rated input current (5A or 1A) of
the product, or CT shall be considered to be used. If the external CT is
connected with other meters, the tandem way shall be used for wiring. Before
removing the product’s current input wiring please cut off CT primary circuit or
short-circuit secondary circuit. For ease of maintenance, we recommend to use
