i.2 Using the Product Safely
18 YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
CAUTION
Crush Hazard
Tighten terminal cover screws and hold the case safely when you move the bypass.
If the bypass or covers fall, it can cause moderate injury.
NOTICE
Use an inverter-duty motor or vector-duty motor with reinforced insulation and windings applicable
for use with an AC drive.
If the motor does not have the correct insulation, it can cause a short circuit or ground fault from insulation
deterioration.
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 do a withstand voltage test or use a megohmmeter or megger insulation tester on the
bypass.
These tests can cause damage to the bypass.
Do not operate a bypass or connected equipment that has damaged or missing parts.
You can cause damage to the bypass and connected equipment.
Do not use steam or other disinfectants to fumigate wood for packaging the bypass. Use
alternative methods, for example heat treatment, before you package the components.
Gas from wood packaging fumigated with halogen disinfectants, for example fluorine, chlorine, bromine, iodine or
DOP gas (phthalic acid ester), can cause damage to the bypass.
