• The total input cable length must be equal to the total | ||
| ||
output cable length in order to prevent unbalanced load |
| |
sharing between two UPS systems under reserve mode |
| |
(i.e. Res1 + OP1 = Res2 + OP2; deviation must be <10%). |
| |
• Parallel configuration only supports 2 UPS systems (1+1 | 3 | |
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 | 4 | |
dissimilar UPS systems will damage the UPS systems | ||
| ||
and create a serious risk of personal injury and property |
| |
damage. |
|
| • Each UPS must have its Parallel group set to 2 and a |
|
|
| 5 |
| different “Parallel ID” that indicates the UPS systems are | 1 |

| |
| being run in parallel. (See Section |
