YASKAWA SIEPYEULA5001C LA500 Technical Manual 111
WARNING
Crush Hazard
Wear eye protection when you do work on the drive.
If you do not use correct safety equipment, it can cause serious injury or death.
Electrical Shock Hazard
After the drive blows a fuse or trips an RCM/RCD, do not immediately energize the drive 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 drive or peripheral devices.
If you do not fix the problem before you operate the drive or peripheral devices, it can cause serious injury or
death.
NOTICE
Damage to Equipment
When you touch the 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 circuitry.
Do not break the electrical connection between the drive and the motor when the drive is
outputting voltage.
Incorrect equipment sequencing can cause damage to the drive.
Before you connect a dynamic braking option to the drive, make sure that qualified personnel
read and obey the Braking Unit and Braking Resistor Unit Installation Manual
(TOBPC72060001).
If you do not read and obey the manual or if personnel are not qualified, it can cause damage to the drive and
braking circuit.
Make sure that all connections are correct after you install the drive and connect peripheral
devices.
Incorrect connections can cause damage to the drive.
Note:
Do not use unshielded cable for control wiring. Use shielded, twisted-pair wires and ground the shield to the ground terminal of the
drive. Unshielded wire can cause electrical interference and unsatisfactory system performance.
