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.
