5.2 Wire Selection Example
POINT
For wiring to comply with the IEC/EN/UL/CSA standard, refer to "MR-CV_/MR-
CR55K_/MR-J4-DU_(-RJ) Instruction Manual". To comply with other standards,
use wires compliant with each standard.
Selection conditions of wire size is as follows.
Wiring condition: In-air, one-row wiring
Wiring length: 30 m or lower (MR-J2S series)
50 m or lower (MR-J4 series)
POINT
If using the existing cables, refer to "[Appendix 2] Introduction to Renewal Tool".
