NOTES:
1
Follow local codes and regulations when selecting field wires, and all above are the minimum size.
2 The wire sizes marked in the table are selected at the maximum current of the unit according to the European Standard,
EN60335-1. Use the wires which are not lighter than the ordinary polychloroprene sheathed flexible cord (code designation
H07RN-F).
When connecting the terminal block with flexible cord, make sure to use
the round crimp-style terminal for connection to the power supply terminal
block.
Place the round crimp-style terminals on the wires up to the covered part
and secure them in place.
When connecting the terminal block with a single core wire,be sure to
perform curing.

3 When transmission cable length is more than 15 meters, a larger wire size should be selected.
4
Use a shielded cable for the transmitting circuit and connect it to ground.
5 If power cables are connected in series, add each unit maximum current and select wires below.
