3.2.2 Single UPS output connection
Normally, output connection of 1~10KVA type is configured with sockets or terminal blocks, users can plug the load
cable into the UPS socket to energize the load as following pictures. Make sure the mains wire and breakers in the
building are enough for the rated capacity of UPS to avoid the hazards of electric shock or fire.
Note: For the type of 6-10KVA, do not use the wall receptacle as the input power source for the UPS, which rated
current is less than the UPS’s maximum input current. Otherwise the receptacle may be burned and destroyed.

3.3 Parallel system of 6-10K UPS installation and output connection
Only 6-10K UPS and containing parallel ports can do parallel operation, other types is not supported.
N+X parallel structure is the most reliable power supply structure at present, N stands for the minimum number of
UPS for the load, X stands for the number of redundant UPS
，
X absolutely means how many UPS could be
malfunctioning at the same time and the parallel UPS system is still steady. The larger X is, the system is more
reliable. N+X is the best method for high reliability. Just install a little more simple accessories, at most 8 UPS
could work together to form a flexible parallel system.
This structure of power supply system increases the power safety and reliability. For example, two single UPS
make up a parallel system to load averagely, when one is malfunctioning, another one can take the whole load
independently. It allows isolation repairs for malfunctioning UPS, and according to users own different
requirements, every single UPS could install manual maintenance bypass switch.
3.3.1 Parallel system installation
The function of parallel operation is an optional function of UPS, users can purchase parallel function parts
(including parallel card and parallel wire) and contact service personnel to install. At most 8 UPS work together by
using parallel wires to form a flexible parallel system. Each UPS should be equipped individual battery pack.

Parallel system installation requirement:
●Install parallel wire, users need to purchase a specific parallel wire from our company, it’s not recommended to
use other type parallel wires. There are 2m length and 5m length to be chosen.
●Prepare wires for terminal block of the UPS based on the wiring spec table above in attention items.
●Each UPS input wiring please comply with the requirements of single UPS wiring.
●Every UPS is recommended to connect together to one common utility power terminal block.
