3. Installation instructions
3.1 Attention items of installation
●The UPS installation environment must be with good ventilation, away from water, flammable gases and
corrosive entities.
●Do not lie down the UPS against the wall so that front and side panel air intake hole, rear panel air outtake
hole will be unobstructed.
●The peripheral environment temperature around the UPS should be within 0 ℃~ 40 ℃.
● If dismantling the machine at low temperatures, there may be condensation droplets, users can not install
or operate it before UPS completely got dry both inside and outside, otherwise there will be danger of
electric shocks.
● Place the UPS near the mains socket so that can cut off ACmains without any delay at any emergent case.
●Make sure the load connect to the UPS is off when users connect the load to UPS, and then turn on the load
one by one later.

4
●Please connect the UPS with the socket which is over-current protected. Do not connect the UPS with the
socket which rated current is less than the Maximum input current of the UPS.
●All the power socket should be configured with earthing device for safety.
●UPS could be electrified or powered no matter the input power cable is tied or not, even when the UPS is off.
The only way to cut off the output is switching off the UPS and disconnecting the mains power supply.
●For all standard type UPS, it is advised to charge the battery over 8 hours before used. Once the AC mains
power energizes the UPS, it will automatically charge the battery. Without prior charging, UPS output
remains as usual but with shorter back-up time than normal.
●When connected to motor, display equipment, laser printer etc, UPS power selection should be based on
the startup power of the load which is usually twice as rated power.
●When wiring, please ensure input cables and output cables are connected firmly.
●If install a leakage current protective switch, please install it on output cable.
●For LEGA31 6-20K Series UPS, before installing, prepare wires for terminal block of the UPS based on the
following tables.

Note: When connecting, please make sure to connect input cables and output cables with terminals firmly.
When the input is three-phase, if the UPS is working on Bypass mode, the total current goes through phase R,
so the line widths of phase R must be the same as output. When the input is single-phase, before doing input
connection, users have to use two short wires to connect R&S and S&T.
3.2 Output connection
Output connection is configured with terminal blocks. 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: 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 6-20K UPS installation
Only 6-20K 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 all the
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.
●The output cables of each UPS are recommended to connect together on a common terminal block, then
output to the load.
●Each UPS should be equipped individual battery pack.
●Wiring installation for parallel UPS system please refer to the wiring diagrams are given below, switches of
6KVA should withstand more than 50A/250VAC, and switches of 10KVA should withstand more than
80A/250VAC, and switches of 15KVA should withstand more than 100A/250VAC, and switches of 20KVA
should withstand more than125A/250VAC.
●Output wiring length requirements: when the distance between the load and each UPS is less than 20
meters, the length difference of cables to the load should be less than 20%; when the distance between the
load and each UPS is more than 20 meters, the length difference of cables to the load should be less than
10%.
>Installation procedure:
①Install parallel wires. Two UPS to form an UPS parallel system, in order to ensure the reliability of the
parallel system, there is only one way to wire two UPS, use two parallel wires to connect two UPS like the
diagram showing below, connection looks like a circle. If three or more than three UPS are needed, the
connection is similar, you can refer to the diagram as below. How many UPS unit, how many parallel wires
you need.
