Note 1) Cable size selection conditions: Ambient temperature 40_C, 3 wires per bundle, and
rated current flowing
2) For the main circuit, use cables with a dielectric strength of 600 V or more.
3) If the cables are laid in a duct (rigid PVC tube or metal pipe), allow for the reduced current
rating applicable to the cables.
4) If the ambient temperature (inside the control panel) is high, cables sheathed with ordi-
nary vinyl will be easily subject to heat deterioration and become unusable in a short pe-
riod of time. To prevent this, always use heat resistant cables.
The types of cable are shown in the table below. Use it in combination with the tables.

Note 1) Use cable with 600 V min. rating for main circuits.
2) Consider allowable current reduction ratio if cables are bundled in PVC or metal ducts.
3) Use temperature-resistant cable under high ambient or panel temperature where nor-
mal vinyl cables rapidly deteriorate.
