Mitsubishi Electric MELSERVO-J3 Series Instruction Manual page 787

APPENDIX
(2) Installation
The MR-J3 series have been approved as the products which have been installed in a control box. The
minimum control box size is based on 150% of each unit combination. And also, design the control box so
that the ambient temperature in the control box is 55
The servo amplifier must be installed in a metal control box.
(3) Short circuit rating (SCCR: Short Circuit Current Rating)
Suitable For Use In A Circuit Capable Of Delivering Not More Than 100 kA rms Symmetrical Amperes, 500
Volts Maximum.
(4) Flange
Mount the servo motor on a flange which has the following size or produces an equivalent or higher heat
dissipation effect.
