Note: When the three-phase four-wire products are for the
three-phase three-wire measurement through the internal DIP
switch settings, the product wiring is required to B-phase voltage
connected to the terminals NO.4, terminals NO.2 are not
connected, B phase current is not connected.
6 Installations
Rail mounting dimensions: 35mm; screw nail installation size:
76X57.8mm, as shown in Figure 5 (in mm).

7 Function Settings
As shown in Figure 1 to open the bottom case, there is a six-bit
code switch on the internal PCB board. The bit 1 and 2 set
measurement faction of active, reactive power and power facto,
the bit 3 sets the output zero to 0V (0mA) or 1V (4mA), bit 4
sets
for nonpolarity and polarity measurement to
distinguish inductive
capacitive, bit 5 is set to the negative power zero offset output,
when zero value is 4mA or 1V, then nonpolarity measurement;
When measured to negative power, output will be less than 4mA
or 1V, the maximum bias output of negative power is to -20%, the
minimum is to 0.8mA or 0.2V(This bit setting is disabled when the
4th bit switch is set to bipolar measurement
