NOTICE: Follow cooling fan replacement instructions. The cooling fan cannot operate properly when installed incorrectly and could
seriously damage the regenerative unit. To ensure maximum useful product life, replace all cooling fans when performing maintenance.
Contact a Yaskawa representative or the nearest Yaskawa sales office to order replacement cooling fans as required.
For regenerative units with multiple cooling fans, replace all the fans when performing maintenance to ensure maximum
product performance life.
WARNING! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Failure to comply can result in serious
personal injury. Before servicing the regenerative unit, disconnect all power to the equipment. The internal capacitor remains charged
even after the power supply is turned off. After shutting off the power, wait for at least the amount of time specified on the regenerative
unit before touching any components.
CAUTION! Burn Hazard. Do not touch a hot regenerative unit heatsink. Failure to comply could result in minor or moderate injury. Shut
off the power to the regenerative unit when replacing the cooling fan. To prevent burns, wait at least 15 minutes and ensure the
heatsink has cooled down.
NOTICE: Follow cooling fan replacement instructions. Improper fan replacement could cause damage to equipment. Make sure the fan
is facing upwards when installing the replacement fan into the regenerative unit. Replace all fans when performing maintenance to help
ensure maximum useful product life.
