7-8 AC Input/Output Wiring (Parallel UPS – Single Input Source)
Parallel UPS Warnings:
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
•
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.
Each UPS must have its Parallel group set to 2 and a
•
different “Parallel ID” that indicates the UPS systems are
being run in parallel. (See
Section 10-5-5
for more details.)
Follow the steps in
Section 7-7
, wiring the UPS systems as shown
in the diagram.
Connect the included parallel UPS cable
A
to the parallel port
B
of each UPS system.
7-9 AC Input/Output Wiring (Parallel UPS – Dual Input Sources)
Parallel UPS Warnings:
The total input cable length must be equal to the total
•

sharing between two UPS systems under reserve mode
(i.e. Res1 + OP1 = Res2 + OP2; deviation must be <10%).
