Note 1. When the wire sizes of L1 and L11 are the same, MCCB or fuse is not required.
2. When using a 100 V class servo amplifier, step down the power supply voltage to
100 V and connect the main circuit power supply lines to L1 and L2. For 1-phase
200 V AC servo amplifiers, connect the lines to L1 and L3.
3. Please use a thermal sensor, etc. for thermal protection of the servo motor.

The control circuit connectors described by rectangles are safely separated from the main circuits described
by circles.
The connected motors will be limited as follows.
(1) HG/HF/HC/HA series servo motors (Mfg.: Mitsubishi Electric)
(2) Using a servo motor complied with IEC 60034-1 and Mitsubishi Electric encoder (OBA, OSA)
