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.
Note:
Refer to Single-Phase Derating on page 317
for applying and protecting the drive when using single-phase input power.
Refer to Factory Recommended Branch Circuit Protection for UL Compliance on page 460
for details on fuse selection.

Factory Recommended Branch Circuit Protection
WARNING! Fire Hazard. Install adequate branch circuit protection according to applicable local codes and this manual. Failure to comply
could result in fire and damage to the drive or injury to personnel. The device is suitable for use on a circuit capable of delivering not more
than 100,000 RMS symmetrical amperes, 240 Vac (200 V class) and 480 Vac (400 V class), when protected by branch circuit protection
devices specified in this manual.
Branch circuit protection shall be provided by any of the following: Non-time delay Class J, T, or CC fuses sized at 300% of the drive input
rating, or Time delay Class J, T, or CC fuses sized at 175% of the drive input rating, or MCCB sized at 200% maximum of the drive input
rating.
Yaskawa recommends installing branch circuit protection according to maintain compliance with UL508C. Semiconductor
protective type fuses are preferred. Alternate branch circuit protection devices are also listed in this manual.
