9-7 Preliminary Checklist (Parallel UPS)

10
Warning: Parallel configuration requires exactly two UPS systems (1+1 redundancy or capacity). Do not attempt to link more than two
UPS systems via parallel configuration. The UPS systems must have the same rating and capacity for parallel UPS installation. Attempting
to link dissimilar UPS systems will damage the UPS systems and create a serious risk of personal injury and property damage.
• All circuit breaker switches should be off, including the breakers of the external battery cabinets.
11
• Confirm that no voltage potential exists between Neutral and Ground.
• Confirm that the input power source matches the rating (voltage, frequency and phase) of the UPS systems.
• Each UPS must have a different "Parallel ID"that indicates the UPS systems are being run in parallel. See
details.
12
Note: After start-up, the UPS systems will perform a brief self-test and display the results on the LCD screen. After a successful self-test, the UPS
systems will provide AC power to the connected equipment load.
