Factory Recommended Branch Circuit Protection
WARNING! Fire Hazard. Branch Circuit protection is required to be installed according to applicable local codes and the
requirements listed on the bypass nameplate. The bypass is suitable for use on a circuit capable of delivering not more than
100,000 RMS symmetrical amperes, 208/240 Vac and 480 Vac with the circuit breaker option or when protected by class J or class
L fuses as specified on the bypass nameplate. Failure to obey can cause fire and damage to the bypass and drive or injury to
personnel.
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.

Wire Selection
Select the correct wires for main circuit wiring.

Wire Selection Precautions
WARNING! Electrical Shock Hazard. Make sure that the protective ground wire conforms to technical standards and local safety
regulations. The IEC/EN 61800-5-1:2007 standard specifies that you must wire the power supply to automatically de-energize when
the protective ground wire disconnects. You can also connect a protective ground wire that has a minimum cross-sectional area of
10 mm
2 (copper wire) or 16 mm 2 (aluminum wire). If you do not obey the standards and regulations, it can cause serious injury or
death. The leakage current of the bypass will be more than 3.5 mA.
Think about line voltage drop before you select wire gauges. Select wire gauges that drop the voltage by 2% or less of
the rated voltage. Increase the wire gauge and the cable length when the risk of voltage drop increases. Calculate line
voltage drop with this formula:
Line voltage drop (V) = × wire resistance (Ω/km) × wiring distance (m) × motor rated current (A) × 10 -3 .

Wire Gauge and Torque Specifications for UL Listing
WARNING! Electrical Shock Hazard. Make sure that the protective ground wire conforms to technical standards and local safety
regulations. The IEC/EN 61800-5-1:2007 standard specifies that you must wire the power supply to automatically de-energize when
the protective ground wire disconnects. You can also connect a protective ground wire that has a minimum cross-sectional area of
10 mm
2 (copper wire) or 16 mm 2 (aluminum wire). If you do not obey the standards and regulations, it can cause serious injury or
death. The leakage current of the bypass will be more than 3.5 mA.
Refer to the following tables for the recommended wire gauges and tightening torques of the main circuit terminals.
Note:
The recommended wire gauges are based on drive continuous current ratings with 75 °C (167 °F) 600 V class copper wire. Assume these
conditions:
•
Ambient temperature: 40 °C (104 °F) or lower
• Wiring distance: 100 m (3281 ft) or shorter
• Normal Duty Rated current value
