is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric shock, wait for at least
the time specified on the warning label, once all indicators are OFF, measure for unsafe voltages to confirm the drive is safe prior to servicing.
CAU ION Burn Hazard. Do not touch a hot drive heatsink. Failure to comply could result in minor or moderate injury. Shut off the power
to the drive when replacing the cooling fan. To prevent burns, wait at least 15 minutes and ensure the heatsink has cooled down.
NO ICE Follow cooling fan and circulation fan replacement instructions. Improper fan replacement may cause damage to equipment. When
installing the replacement fan into the drive, make sure the fan is facing upwards. Replace all fans when performing maintenance to help
