Fasten the flange of the actuator on the load machine with flat washers and high-tension bolts.
When tightening, use a torque wrench to control the tightening torque.
The tightening torques are shown in the table below:

For correct wiring operation, refer to Mitsubishi Electric servo amplifier
"MR-J4-_B(1)-RJ920J Product Specifications" (No. BCN-B72000-230) or
"MR-J4W2-0303B-MX940J Product Specifications" (No. BCN-B72000-227)".

Motor cable and encoder cable
Do not pull the cables with a strong force. The connection points may be damaged. Install the
cable wiring with slack so that no tension is applied to the actuator. Provide a sufficient bending
radius (R = 40 mm or more), especially when the cable flexes.
Do not apply torque or load to the hollow shaft (sleeve).
The hollow shaft (sleeve) is adhered to the output rotary shaft. When a load is applied
to the hollow shaft (sleeve), delamination may occur on the output shaft and hollow
shaft (sleeve).
Do not apply or use any torque, moment load or thrust load directly to the hollow shaft
(sleeve).
Do not disassemble/reassemble the actuator.
The actuator uses many precision parts. We cannot guarantee if assembly or
disassembly by the customer will cause lower precision and performance.
