4.1.3 MR-J3W series power supply wire size
POINT
Wires indicated in this section are separated wires.
To comply with the UL/CSA Standard, use the wires shown in appendix 4 for
wiring.
To comply with other standards, use a wire that is complied with each standard.
Selection condition of wire size is as follows.
Construction condition: One wire is constructed in the air
Wire length: 30m or less
(1) 200 V class wires for power supply wiring
The following diagram shows the wires used for wiring. Use the wires given in this section or equivalent.
