Warning: Parallel redundancy requires exactly two UPS systems (1+1 redundancy ). Do not attempt to link more than two UPS systems via parallel redundancy. The UPS systems must have the same rating and capacity for parallel redundancy 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.

•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.

•You must use the control panel to set the parallel ID numbers of the UPS systems to be 1 and 2. See section 10-11 of the owner’s manual for information about setting the parallel ID numbers.

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.

1.6.8 Start-Up Procedure (Parallel UPS)
