8.0Start-up/Scheduled Maintenance/Part Replacement

8.1Start-up

The startup of the UPS equipment is broken up in several steps. These steps are as follows:

1.Initial Condition: This is where the service technician checks the unit for physical damage and verifies the installation of the UPS (electrically).

2.Static Checks: This step verifies the proper settings within the UPS logic.

3.Wiring Check: The wiring to (power cables) and from (control wires) the battery cabinet.

4.Main Voltage Check: The input voltages are checked to verify they are within the range.

5.Energizing the UPS: This step begins the internal self-checks within the processor logic.

6.Output Voltage Check: The output voltages are checked to verify they are within range.

7.EPO (Emergency Power Off): The EPO is operated to verify its operation in case of an emergency.

8.Load Testing: Performed if load is available.

9.Generator Testing: Performed if Generator is available.

10.Internal/External Maintenance Bypass: This verifies the proper operation of the Maintenance Bypass.

8.2Preventive Maintenance

The TOSHIBA 4200FA Uninterruptible Power Systems have been designed to provide no years of trouble-free operation requiring a minimum of preventive maintenance.

The best preventive measure that the UPS user can take is to keep the area around the unit, particularly the air inlet vents, clean and free of moisture and dust accumulations. Schedule authorized TOSHIBA service centers to perform an internal parts inspection semi-annually.
