NOTE:
1
Follow local codes and regulations when selecting field wires, and all the above are the minimum wire size.
2
Use the wires which are not lighter than the ordinary polychloroprene sheathed flexible cord. (Cord designation H07RN-F).
3
The wire sizes marked with *1 in the above table are selected at the maximum current of the unit according to the European
Standard, EN60335-1.
4
When transmission cable length is more than 15 meters, a larger wire size should be selected.
5
Install main switch and ELB for each system separately. Select the high response type ELB that is acted within 0.1second.
6
In the case that power cables are connected in series, add each unit maximum current and select wires below.

<Attentions when Connecting the Power Supply Wiring>
1
When connecting the terminal block using stranded
wire, 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.
2
When connecting the terminal block using a single core wire,
be sure to perform curing.
