* Refer to the NOTES: in the next page 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.
