Thank you for purchasing our products!
Please read this manual before using the product.
nJoy is a brand of power and backup protecon products that
create soluons for mulple levels of environment complexity,
residenal to industrial.
This UPS will protect your electronic equipment from physical
damage and will provide emergency baery backup power to
prevent data loss in the event of power problems.
All safety instrucons in this document must be read, understood and
followed.
1.1 Transportaon and Storage
Please transport the UPS system only in the original packaging to
protect against shock and damage.
The UPS must be stored in the room where the temperature is well
regulated. Ambient temperature should not exceed 40°C.
1.2 Preparaon
Condensaon may form if the UPS system is moved immediately from
cold to warm environment. The UPS system must be absolutely dry before
being installed. Please allow at least two hours for the UPS system to
acclimate the environment.

Do not install the UPS system near water or in moist environments.
Do not install the UPS system where it would be exposed to direct
sunlight or nearby heat source.
Do not block venlaon holes on the UPS housing.
1.3 Installaon
Do not connect appliances or devices which would overload the UPS
(e.g. big motor-type equipment) to the UPS output terminal.
Place cables in such a way that no one can step on or trip over them.
Do not block air vents on the housing of the UPS. Ensure proper unit
spacing of venlaon.
UPS came equipped with grounding terminal, in the nal installaon
phase, connect grounding/earthing wire to the external UPS baery
cabinets or appropriate grounding terminals.
The UPS can be installed only by qualied maintenance personnel.
An appropriate disconnect device such as short-circuit backup
protecon should be incorporated during installaon.
An integral emergency shuto switch which prevents addional load
from the UPS in any mode of operaon should be implemented during the
installaon.
Secure the grounding/earthing wire before connecng to any live wire
terminal.
Installaon and Wiring must be in accordance with the local electrical
laws and regulaons.

1.4 Connecon Warnings
There is no standard backfeed protecon inside of the UPS. However,
there are relays on the Input to cut o line voltage and while the neutral is
sll connect to UPS.
This UPS should be connected with TN grounding/earthing system.
The power input for this unit must be three-phase rated in accordance
with the equipment nameplate. It also must be suitably grounded.
Use of this equipment in medical instrument of any life-sustaining
equipment where failure of this equipment can reasonably be expected to
cause the failure of the life-sustaining equipment or to signicantly aect
its safety or eecveness is not recommended. Do not use this equipment
in the presence of a ammable mixture with air, oxygen or nitrous oxide.
Connect grounding terminal of UPS to a grounding electrode conductor.
In accordance with safety standard EN-IEC 62040-1, installaon
has to be provided with a «Backfeed Protecon» system, as for example
a contactor, which will prevent the appearance of voltage or dangerous
energy in the input mains during a mains fault (respect the wiring diagram
of «Backfeed Protecon» depending if the equipment is with signal or three
phase input).
HIGH LEAKAGE CURRENT! EARTH CONNECTION ESSENTIAL
BEFORE CONNECTING SUPPLY.

1.5 Operaon
Do not disconnect the grounding/earthing conductor cable on the UPS
or the building wiring terminals under any circumstance.
The UPS system features its own, internal current source (baeries).
The UPS output sockets or output terminal blocks may be electrically live
even if the UPS system is not connected to the building mains/live wires.
(only for standard models)
In order to fully disconnect the UPS system, rst press the “OFF” buon
and then disconnect the mains/live wires.
Ensure that no liquid or other foreign objects can enter into the UPS
system.
The UPS can be operated by any individuals with no previous
experience.
There can be no derivaon in the line that goes from the «Backfeed
Protecon» to the UPS, as the standard safety would be infringed.
Warning labels should be placed on all primary power switches installed
in places away from the unit to alert the electrical maintenance personnel
of the presence of a UPS in the circuit. The label will bear the following or
an equivalent text:
Before working on this circuit!
- Isolate Uninterruptible Power Supply (UPS).
- Then check for Hazardous Voltage between all terminals
including the protected earth.
Risk of Voltage Backfeed!

2.1 Unpacking and Inspecon
Unpack the package and check the package contents. The shipping
package should contain:
● One UPS
● One user manual
● One monitoring soware CD
● One RS-232 cable (opon)
● One USB cable
● One parallel cable (only available for parallel model)
● One shared current cable (only available for parallel model)
These series came with a VAC system: 400V. Please refer to the following
table.
We also oer oponal parallel funcon for this model upon request. The
UPS with parallel funcon is called the “Parallel model”. We have detail
installaon and operaon procedure of the Parallel Model in the following
chapter.

NOTE!
Before the installaon, please inspect the unit. Be sure that there is no physical
damage to the unit. Do not turn on the unit and nofy the carrier and dealer
immediately if there is any damage or missing parts and accessories. Please
keep the original packaging for future use. It is recommended to keep each
equipment and baery set in their original packaging because they have been
designed to provide maximum protecon during transportaon and storage.

2.3 Single UPS Installaon
Installaon and wiring must be carried out in accordance with the local
electric laws and regulaons by trained professionals.
1) Make sure that the mains wire and breakers of the building are rated for
the capacity of the UPS to prevent electric shock or risk of re.

NOTE 1: The cable for Ranger 60KR should be able to withstand over
120A current. It is recommended to use AWG 4 or thicker wire for Phase
and AWG 1 or thicker wire for Neutral for safety and eciency.
NOTE 2: The selecons for color of wires should be followed by the local
electrical laws and regulaons.
5) Remove the terminal block cover at the rear panel of UPS. Then connect
2) Switch o the mains switch in the building before installaon.
3) Turn o all the connected devices before connecng to the UPS.
4) Prepare wires based on the following table:
Model Wiring spec (AWG)
Input(Ph) Output(Ph) Neutral Baery Ground
Ranger 60KR 4 4 1 1 4
the wires according to the following terminal block diagrams: (Connect
the grounding/earthing wire rst when making other wire connecons.
Remove the grounding/earthing wire last when connecng the UPS!)

NOTE!
Do not use the wall receptacle as the input power source for the UPS, as its
rated current is less than the UPS’s maximum input current. The receptacle
may be damaged and destroyed.

NOTE 1: Make sure that the wires are connected securely with the
terminals.
NOTE 2: Please install the output breaker between the output terminal
and the load, and the breaker should have leakage current protecve
funcon if necessary.
6) Put the terminal block cover back at the rear panel of the UPS.
TO UPS BAT-
● Make sure a DC breaker or other protecve device between UPS and
the external baery pack is installed for added safety. If not, please
install it carefully. Switch o the baery breaker before installaon.
NOTE: Set the baery pack breaker in “OFF” posion and then install
the baery pack.
● Pay special aenon to the rated baery voltage marked on the rear
panel. If you want to change the numbers of the baery in a chain,
make sure you modify the UPS seng accordingly. Connecon with
wrong baery voltage may cause irreversible damage of the UPS.
● Pay special aenon to the polarity marking on external baery
terminal block. Connecon with wrong baery voltage may cause
irreversible damage of the UPS.

2.4 UPS Installaon for Parallel System
If the UPS is only for single operaon, you may skip this secon.
1) Install and wired the UPS according to the secon 2-3.
2) Connect the output wires of each UPS to an output breaker.
3) Connect all output breakers to a major breaker. This major output
breaker will then connect directly to the loads.
4) Either common baery packs or independent baery packs for each
UPS are allowed.
5) Refer to the following wiring diagram:
Wiring diagram of parallel system for Ranger 60KR
● Make sure the protecve grounding/earthing wiring is adequate.
The current spec, color, posion, connecon and conductance
reliability of the wire should be veried.
● Make sure the ulity input & output wiring is rated correctly. The
current spec, color, posion, connecon 8 and conductance reliability
of the wire should be veried. Make sure the L/N side is correct, not
reverse or short-circuited.
