11. OPTIONS AND PERIPHERAL EQUIPMENT
(1) MR-J4-500TM or less/MR-J4-350TM4 or less
Always remove the wiring from across P+ to D and fit the regenerative option across P+ to C. G3 and
G4 are thermal sensor's terminals. Between G3 and G4 is opened when the regenerative option
overheats abnormally.
Always remove the lead from across P+ to D.

Note 1. When using the MR-RB50, MR-RB5N, MR-RB51, MR-RB3M-4, MR-RB3G-4, or
MR-RB5G-4, forcibly cool it with a cooling fan (1.0 m
mm).
2. When the ambient temperature is more than 55 °C and the regenerative load ratio
is more than 60% in MR-RB30, MR-RB31, MR-RB32, and MR-RB3N, forcefully
cool the air with a cooling fan (1.0 m
fan is not required if the ambient temperature is 35 °C or less. (A cooling fan is
required for the shaded area in the following graph.)
