9. Disconnect all power connectors from the front of the ACCU.
10. Ensure that the AC mains switch and the circuit breakers are all in OFF
position.
11. Put back the ACCU front cover.
12. Switch on site power.
13. Switch on ACCU main switch.
14. Switch on the circuit breaker for the Climate Unit (CLU).
15. Measure the output AC voltage from the CLU output connector, using
a digital multimeter.
16. Switch off the circuit breaker for the CLU.
17. Repeat Step 14 on page 27 to Step 16 on page 27 for each circuit breaker
and output connector for Power Supply Unit (PSU) 1, PSU 2, and PSU 3
respectively.
18. If any of the output voltages are outside the 190 – 260 V AC range,
switch off the site power and ACCU mains switches and check the ACCU
strapping before proceeding.
Note: To prevent personal injury or damage to equipment, never connect
a PSU to an ACCU output that is outside the 190 – 260 V AC range.
19. Check that the output voltage at the service outlet is the same as the local
single-phase voltage.
20. Connect all power connectors to the front of the ACCU.
