YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference 771
WARNING
Crush Hazard
Wear eye protection when you do work on the bypass.
If you do not use correct safety equipment, it can cause serious injury or death.
Electrical Shock Hazard
After the bypass blows a fuse or trips a GFCI, do not immediately energize the bypass or operate
peripheral devices. Wait for the time specified on the warning label at a minimum and make sure
that all indicators are OFF. Then check the wiring and peripheral device ratings to find the cause of
the problem. If you do not know the cause of the problem, contact Yaskawa before you energize the
bypass or peripheral devices.
If you do not fix the problem before you operate the bypass or peripheral devices, it can cause serious injury or
death.
NOTICE
Damage to Equipment
When you touch the bypass, drive, and 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.
Do not break the electrical connection between the bypass and the motor when the bypass is
outputting voltage.
Incorrect equipment sequencing can cause damage to the 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.
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.
Unshielded wire can cause electrical interference and unsatisfactory system performance.
