To maintain the performance and reliability of the drive, examine the drive annually. Contact ABB Service at least once in three years to replace old components. The recommended maintenance and component replacement intervals are based on operation in specified ambient conditions. Maintenance 75 Cleaning the heat sink The fins of the drive heat sink become dusty from the cooling air. If the heat sink is not clean, this can cause the drive to give overtemperature warnings and faults. WARNING! Obey the instructions in Safety instructions on page 13. Ignoring the instructions can cause physical injury or death, or damage to the equipment. WARNING! Use a vacuum cleaner with an antistatic hose and nozzle. A normal vacuum cleaner can cause static discharges which can cause damage to circuit boards. To clean the heat sink: 1. Stop the drive and disconnect it from the input power. 2. Wait for 5 minutes and measure to make sure that there is no voltage. Refer to Precautions before electrical work on page 15. 3. Remove the cooling fan. Refer to Replacing the cooling fans on page 76. 4. Blow clean, dry and oil free compressed air from the bottom of the heat sink to the top and use a vacuum cleaner at the air outlet to trap the dust. If there is a risk that dust can go into other equipment, clean the heat sink in another room. 5. Install the cooling fan. 76 Maintenance Replacing the cooling fans This instruction is applicable only to frame sizes R1, R2 and R3. Frame R0 does not have a cooling fan. Refer to Maintenance intervals on page 74 for the fan replacement interval in normal operating conditions. Parameter 05.04 Fan on-time counter shows the running time of the cooling fan. After you replace the fan, reset the fan counter. Refer to the ACS380 Firmware manual (3AXD50000029275 [English]). You can get replacement fans from ABB. Use only ABB specified spare parts. To replace the cooling fan WARNING! Obey the instructions in Safety instructions on page 13. Ignoring the instructions can cause physical inj |
