* Refer to the NOTES for selection of the power source cable size.
NOTES:
1) Follow local codes and regulations when selecting field wires.
2) The wire sizes marked with *1 in the table of this page are selected at the maximum current of the unit according to the
European Standard, EN60 335-1. Use the wires which are not lighter than the ordinary tough rubber sheathed flexible
cord (code designation H05RN-F) or ordinary polychloroprene sheathed flexible cord (code designation H05RN-F).
3) The wire sizes marked with *2 in the table of this page are selected at the maximum current of the unit according to the
wire, MLFC (Flame Retardant Polyflex Wire) manufactured by Hitachi Cable Ltd., Japan.
4) Use a shielded cable for the transmitting circuit and connect it to ground.
5) In the case that power cables are connected in series, add each unit maximum current and select wires below.

NOTE:
The maximum current value above is for the single wiring only.
However, the power source wirings are bundled together in the actual field wiring installation. In this case, the maximum
current value of the wiring is decreased of 50 to 70% due to the heat generation of wiring during the operation.
Therefore, follow Table 6.1 for the field wiring.
Install a multi-pole main switch with a space of 3.5mm or more between each phase.
