Routine End-User Preventive Maintenance Program
Definition
The Routine end-user preventive maintenance program can be carried out by:
-
Trained and qualified end-user personnel.
-
Trained and qualified maintenance services provider personnel.
-
Schneider Electric Services representatives.
The Routine end-user preventive maintenance program comprises:
-
Limited visual inspection.
-
Function checks.
-
Replacement by standard exchange of certain assemblies.
The Routine end-user preventive maintenance program must be performed every year in the case of normal operating conditions. Refer to the recommended frequency for the Routine end-user maintenance program for other cases.
Procedures
The Routine end-user procedures are described in detail in MasterPacT MTZ with MicroLogic X Control Units - End-User Maintenance Procedures for IEC DevicesMasterPacT NT/NW - Routine and Intermediate End-User Maintenance Procedures for IEC Devices.
The Routine end-user procedures are described in detail in DOCA0306•• MasterPacT MTZ IEC Circuit Breakers with MicroLogic Active Control Unit - End-User Maintenance Procedures .
