Cable length: Limit voltage drop to less than 2%.
Increase cable gauge if voltage drop is 2% or more.
If the interconnect cable exceeds 30M in length 2.5mm thick
cable should be used.
The cable specifications are based on the assumption that a
metal or plastic conduit is used with no more than three cables
contained in a conduit and a voltage drop of 2%.
Preparing cable
1.
Selecting cable
Select the power source cable and connecting cable in
accordance with the specifications mentioned below:
a. Power source cable
3-core* 2.5mm² or more, conformed with 60245 IEC57.
When selecting the power source cable length, make sure
that voltage drop is less than 2%. If the voltage drop is
more than 2%, increase cable thickness.
b. Connecting cable
3-core* 1.5mm², conformed with 60245 IEC57.
2. Arrange each wire length as shown. Make sure that each
wire is stripped 10mm from the end.
3. Attach round crimp-type terminal to each wire as shown.
Select the size of round crimp-type terminal after
considering the specifications of terminal block and
wire diameter.
