6-8 AC Input/Output Wiring (Parallel UPS – Single Input)
Parallel Redundancy Warnings:
2
• 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. IP1 + OP1 = IP2 + OP2; deviation must be <10%).
3
• Parallel redundancy only supports 2 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
4
dissimilar UPS systems will damage the UPS systems
and create a serious risk of personal injury and property
damage.
• Follow the steps in Section
1
5
in the diagram.
• 2 Connect the included parallel redundancy cable
redundancy port B of each UPS system.
