power source is normal, the UPS system is ready for start-up.
Note: If the UPS system remains off for an extended period of time, it
should be turned on periodically to allow the batteries to recharge. The
UPS system should be turned on and the batteries should be recharged
at least one uninterrupted 24-hour period every 3 months. Failure
to recharge the batteries periodically may cause irreversible battery
damage.

1.6.7 Preliminary Checklist (Parallel UPS)

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.
