ABB Water Drive ACQ580-01-430A-4

Parameter 05.04 Fan on-time counter indicates the running time of the cooling fan. Reset the counter after a fan replacement. See the firmware manual.

In a speed-controlled fan, the speed of the fan matches the cooling needs. This increases the life span of the fan.

Main fans are speed controlled. When the drive is stopped, the main fan runs at low speed until the drive cools down. IP21 (UL Type 1) frames R5..R9 and all IP55 (UL Type 12) frames have auxiliary fans that are not speed controlled and run all the time when the control unit is powered.

Replacement fans are available from the manufacturer. Do not use other than specified spare parts.

Electrical safety in installation, start-up and maintenance

These electrical safety precautions are for all personnel who do work on the drive, motor cable or motor.

Check quality of supply voltage

Inspect dustiness, corrosion or temperature

Inspect IP66 (UL Type 4X) frames R1..R3: Drive cover and gasket assembly

Warning: This procedure requires a qualified electrical professional. Do not proceed if you are not qualified.

Before starting, identify the work location and equipment.

All possible voltage sources disconnected and re-connection locked out and tagged out?

All dangerous external voltages from the control circuits disconnected?

Waited 5 minutes after disconnecting power from the drive to let the intermediate circuit capacitors discharge?

Protected any other energized parts in the work location against contact?

Special precautions taken when close to bare conductors?

Voltage between the drive input power terminals (L1, L2, L3) and the grounding (PE) busbar

Voltage between the drive output terminals (T1/U, T2/V, T3/W) and the grounding (PE) busbar
