General Safety
General Precautions
• Some figures in the instructions include options and bypasses without covers or safety shields to more clearly show the inside of the bypass. Replace covers and shields before
operation. Use options and bypasses only as specified by the instructions.
•
The figures in this manual are examples only. All figures do not apply to all products included in this manual.
•
Yaskawa can change the products, specifications, and content of the instructions without notice to make the product and/or the instructions better.

DANGER
Do not ignore the safety messages in this manual.
If you ignore the safety messages in this manual, it will cause serious injury or death. The manufacturer is not
responsible for injuries or damage to equipment.
Electrical Shock Hazard
Do not examine, connect, or disconnect wiring on an energized bypass. Before servicing,
disconnect all power to the equipment and wait for the time specified on the warning label at a
minimum. The internal capacitor stays charged after the bypass is de-energized. The charge
indicator LED extinguishes when the DC bus voltage decreases below 50 Vdc. When all indicators
are OFF, remove the covers before measuring for dangerous voltages to make sure that the bypass
is safe.
If you do work on the bypass when it is energized, it will cause serious injury or death from electrical shock.
