The complete maintenance schedule is available on the Internet (www.abb.com/drivesservices). For more information, consult your local ABB Service representative (www.abb.com/searchchannels).
Page 66
Replacement Note: • Maintenance and component replacement intervals are based on the assumption that the equipment is operated within the specified ratings and ambient conditions. ABB recommends annual drive inspections to ensure the highest reliability and optimum performance. • Long term operation near the specified maximum ratings or ambient conditions may require shorter maintenance intervals for certain components.
Maintenance 67 Maintenance timers and counters The control program has maintenance timers and counters that can be configured to generate a warning when a pre-defined limit is reached. Each timer/counter can be set to monitor any parameter. This feature is especially useful as a service reminder. For more information, see the firmware manual.

Internal cooling circuit 83 1 1. Open the bleed valve of the pump to let out any air. 1 2 . Re-check the pressure and add coolant if necessary. 1 3 . Start the coolant pump. Let any air remaining in the system out through the bleed valve at the cooling unit.
Coolant type Antifrogen® L (by Clariant International Ltd, www.clariant.com) 25% or 50% mixture, available from Clariant distributors and ABB Service representatives. Note: Do not dilute the coolant. It is ready to use. Antifrogen® L 25% mixture is usable in storage temperatures down to -16 °C (3.2 °F).
