WARNING
Electrical Shock Hazard
Do not modify the bypass body, drive body, bypass circuitry, or drive circuitry.
Modifications to bypass and drive body and circuitry can cause serious injury or death, will cause damage to the
bypass and drive, and will void the warranty. Yaskawa is not responsible for modifications of the product made by
the user.
Sudden Movement Hazard
Make sure that you align the phase order for the bypass and motor when you connect the motor to
output terminals U/T1, V/T2, and W/T3.
If the phase order is incorrect, it can cause the motor to run in reverse. If the motor accidentally runs in reverse, it
can cause serious injury or death.
CAUTION
Burn Hazard
Do not touch a hot drive heatsink. De-energize the drive, wait for a minimum of 15 minutes, then
make sure that the heatsink is cool before you replace the cooling fans.
If you touch a hot drive heatsink, it can burn you.
NOTICE
Damage to Equipment
When you touch the drive and bypass circuit boards, make sure that you observe correct
electrostatic discharge (ESD) procedures.
If you do not follow procedures, it can cause ESD damage to the drive and bypass circuitry.
Use the instructions in this manual to replace the cooling fans. When you do maintenance on the
fans, replace all the fans to increase product life.
If you install the fans incorrectly, it can cause damage to the drive and bypass.
Make sure that all connections are correct after you install the bypass and connect peripheral
devices.
Incorrect connections can cause damage to the bypass.
Do not energize and de-energize the bypass more frequently than one time each 30 minutes.
If you frequently energize and de-energize the bypass, it can cause failure.
Do not operate a bypass or connected equipment that has damaged or missing parts.
You can cause damage to the bypass and connected equipment.
Note:
Do not use unshielded cable for control wiring. Use shielded, twisted-pair wires and ground the shield to the ground terminal of the bypass.
Incorrect wiring can cause electrical interference and unsatisfactory system performance.
