3.6 Main Circuit Wiring
This section describes the functions, specifications, and procedures required to safely and properly wire the main circuit in
the drive.
NOTICE:
Do not solder the ends of wire connections to the drive. Soldered wiring connections can loosen over time. Improper wiring practices
could result in drive malfunction due to loose terminal connections.
NOTICE:
Do not switch the drive input to start or stop the motor. Frequently switching the drive on and off shortens the life of the DC bus
charge circuit and the DC bus capacitors, and can cause premature drive failures. For the full performance life, refrain from switching the
drive on and off more than once every 30 minutes.
Refer to Input Fuse Installation on page 248 for details on fuse selection.

4A0002 to 4A0072, and 5A0003 to 5A0052).
Wiring Fuses for Models 4A0930 and 4A1200
NOTICE:
If a fuse is blown or an Ground Fault Circuit Interrupter (GFCI) is tripped, check the wiring and the selection of peripheral devices
to identify the cause. Contact Yaskawa before restarting the drive or the peripheral devices if the cause cannot be identified.
Install a fuse on the input side to protect drive wiring and prevent other secondary damage. Wire the fuse so that leakage
current in the upper controller power supply will trigger the fuse and shut off the power supply.
Select the appropriate fuse from
Table 3.2 .
