Safety Precautions

DANGER
Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an energized drive. 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 drive 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 drive is safe. Failure to obey will cause death or serious injury.
WARNING
Electrical Shock Hazard. Do not operate equipment when covers are missing. Some figures in this section
include drives without covers or safety shields to more clearly show the inside of the drive. Replace covers and shields before
operation. Use drives only as specified by the instructions. Failure to obey can cause death or serious injury.
WARNING
Electrical Shock Hazard. Do not work on the drive or around the drive while wearing loose clothing or jewelry.
Tighten loose clothing and remove all metal objects such as watches or rings. Failure to obey can cause death or serious injury.
WARNING Electrical Shock Hazard. Do not remove covers or touch circuit boards while the drive is energized. Failure to
obey can cause death or serious injury.
WARNING
Electrical Shock Hazard. Only let authorized persons install, wire, maintain, examine, replace parts, and
repair the drive. Failure to obey can cause death or serious injury.
WARNING Electrical Shock Hazard. Do not make changes to the drive body or drive circuitry. Failure to obey can cause
death or serious injury and will void warranty. Yaskawa is not responsible for changes to the product made by the user.
WARNING
Fire Hazard. Tighten all terminal screws to the correct tightening torque. Connections that are too loose or too
tight can cause incorrect operation and damage to the drive. Incorrect connections can also cause death or serious injury from
fire.
CAUTION Crush Hazard. Do not hold the drive by the front cover or terminal cover. Tighten the screws correctly before
moving the drive. Failure to obey can cause minor to moderate injury.
NOTICE
Observe correct electrostatic discharge (ESD) procedures when touching the drive. Failure to obey can cause
ESD damage to the drive circuitry.
NOTICE Do not lift the drive with the cover removed. Failure to obey can cause damage to the drive board and terminal
block.
NOTICE
Do not use unshielded wire for control wiring. Use shielded, twisted-pair wires and ground the shield to the
ground terminal of the drive. Failure to obey can cause electrical interference and unsatisfactory system performance.
NOTICE Do not change the drive circuitry. Failure to obey can cause damage to the drive and will void warranty.
Yaskawa is not responsible for modifications of the product made by the user.
NOTICE
Make sure that all connections are correct after you install the drive and connecting peripheral devices.
Failure to obey can cause damage to the drive.

Before Installing the Option Card

Prior to installing the Communication Option Card, wire the inverter drive and connect to the drive terminals. For
more information on wiring and connecting the inverter drive, refer to the manual packaged with the inverter
drive.
Verify that the inverter drive runs normally without the option installed.

Installing the Option on a L1000A

1.
Turn off the power. Wait until the CHARGE LED turns off and then remove the cover. Refer to the drive
manual for direction on removing the front cover.
2.
Plug the option card (E) to the CN5-A connector (C).
Fieldbus option cards must always be plugged into CN5-A connector.
3.
Connect the ground wire (F) to option card and fix with screw (1).
Select shortest possible cable for ground connection.
