Tripp Lite SU80KX AC Input/Output Wiring Parallel UPS Single Input Source, Parallel UPS Warnings

7 – Wiring (continued)	1
7-8 AC Input/Output Wiring (Parallel UPS – Single Input Source)
Parallel UPS 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. 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 10-5-5for more details.)
•1	Follow the steps in Section 7-7, wiring the UPS systems as shown
	in the diagram.
•2	Connect the included parallel UPS cable A to the parallel port B			B	6
	of each UPS system.
