(1) Peripheral device and power wiring
The followings are selected based on IEC/EN 61800-5-1, UL 508C, and CSA C22.2 No. 14.
(a) Local wiring
The following table shows the stranded wire sizes [AWG] symbols rated at 75 °C/60 °C.

Note 1. Select wire sizes depending on the rated output of the servo motors. The values in the table are sizes based on rated output of
the servo amplifiers.
2. The following shows the PE terminal specifications of the servo amplifier.
Screw size: M4
Tightening torque: 1.2 [N•m]
Recommended crimp terminals: R2-4 (Manufactured by JST)
Crimping tool: YPT-60-21 (Manufactured by JST)
3. "(S)" means 1-phase 200 V AC power input and "(T)" means 3-phase 200 V AC power input in the table.
(b) Selection example of MCCB and fuse
Use T class fuses or molded-case circuit breaker (UL 489 Listed MCCB) as the following table. The
T class fuses and molded-case circuit breakers in the table are selected examples based on rated
I/O of the servo amplifiers. When you select a smaller capacity servo motor to connect it to the servo
amplifier, you can also use smaller capacity T class fuses or molded-case circuit breaker than ones
in the table. For selecting ones other than Class T fuses and molded-case circuit breakers below
and selecting a Type E Combination motor controller, refer to section 11.6.

Note. "(S)" means 1-phase 200 V AC power input and "(T)" means 3-phase 200 V AC power input in the table.
(c) Power supply
This servo amplifier can be supplied from star-connected supply with grounded neutral point of
overvoltage category III (overvoltage category II for 1-phase servo amplifiers) set forth in IEC/EN
60664-1. For the interface power supply, use an external 24 V DC power supply with reinforced
insulation on I/O terminals.
