5.5 System Test Procedure
The UPS test procedure checks the control functions of the UPS, the mimic flow chart LEDs and the audible
alarm. This self-test is password controlled and menu driven. It can be carried out from the operator control
and display panel by the operator and takes 5 seconds.
Test procedure:
1. Select the Command menu on the LCD screen on the operator control and display panel of the UPS.
Use the right or left arrow key to navigate to the Command menu.
2. Select the System test option.
Use the Shift key (F1) and up and down arrow keys (F2, F3) to highlight the desired test. Press the Enter key
(F4).
When prompted, enter each password digit with up arrow (F2) and use right arrow (F3) to access next field.
Press the Enter key (F4) when all digits have been entered.
3. Wait until the test completes.
After five seconds, a pop window will appear to showing the result of this diagnosis: rectifier, inverter, monitor
OK or fault.
4. Stop the test.
If required, the test may be stopped before completion by selecting Stop testing on the Command menu.
5.6 UPS Shutdown Procedures
5.6.1 Procedures For Completely Powering Down UPS
Caution
The following procedures will switch off all power to the load.
The following procedures are used to completely power down the UPS and load. All power switches, isolators
and circuit breakers will be open and the power will be removed from the load. In a parallel system, perform
each step of the procedures in every UPS module before proceeding to the next step.
1. Press the EPO key on the UPS operator control and display panel. This disables the rectifier, inverter, static
switch and battery operation, and the corresponding UPS is isolated from the load.
Note: Unless in an emergency situation, do not press the remote EPO key.
2. Open the rectifier input switch, bypass input switch and BCB.
In a parallel system, at this point, other UPSs report Parallel Comm. Fail, which is normal. Other UPSs continue
to power the load through the inverter.
All of the indicators and the LCD on the operator control and display panel will extinguish as the mains-driven
internal power supplies decay.
3. Open the output switch of the UPS.
Warning: hazardous battery voltage
After the UPS is powered down completely, the battery terminals still remain energized at hazardous voltage levels.
