1 Overview
This manual shows you how to replace the cooling fans, circuit board cooling fans, and
circulation fans on Yaskawa drives.
2 Explanation of Signal Words
WARNING Read and understand this manual before you install, operate, or do maintenance on the
drive. Install the drive as specified by this manual and local codes. The symbols in this section identify safety
messages in this manual. If you do not obey these safety messages, the hazards can cause serious injury, death,
or damage to the products and related equipment and systems.
These identifier words categorize and emphasize important safety precautions in these
instructions.
DANGER This signal word identifies a hazard that will cause serious injury or death if you do not
prevent it.
WARNING This signal word identifies a hazard that can cause death or serious injuries if you do not
prevent it.
CAUTION Identifies a hazardous situation, which, if not avoided, can cause minor or moderate injury.
NOTICE This signal word identifies a property damage message that is not related to personal
injury.
3 Section Safety
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. If you do work on the drive when it is
energized, it will cause serious injury or death from electrical shock.
DANGER Electrical Shock Hazard. Disconnect all power to the drive and wait for the time specified
on the warning label before you remove covers. Check the drive for dangerous voltages before servicing or repair
work. If you do work on the drive when it is energized and there is no cover over the electronic circuits, it will
cause serious injury or death from electrical shock. The drive has internal capacitors that stay charged after you
de-energize the drive.
WARNING Electrical Shock Hazard. The motor will run after you de-energize the drive. PM motors
can generate induced voltage to the terminal of the motor after you de-energize the drive. If you touch a motor
that is moving or energized, it can cause serious injury or death.
WARNING Electrical Shock Hazard. Do not wear loose clothing or jewelry when you do work on the
drive. Tighten loose clothing and remove all metal objects, for example watches or rings. Loose clothing can
catch on the drive and jewelry can conduct electricity and 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 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.
NOTICE 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.

CAUTION Injury to Personnel. Some fan units are not easily accessible from a standing position.
Make sure that you can safely and comfortably remove and replace the fan. If you try to remove a fan that you
cannot easily access, the fan unit can fall and cause minor to moderate injury.
NOTICE 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.
