CAUTION: Follow the instructions in the manual before placing
or moving the inverter.
CAUTION: Make sure there isn’t any electrical arcing danger
around the operation area before installation.
CAUTION:Connect the inverter to the battery is highly
recommended; the minimum capacity (Ah) of the batteryshould be 5
times of the inverter rated output power (P) divide by the battery
voltage (V), which means Ah=5×(P/V).
WARNING: Keep the inverter away from children.

5. Safety cautions for installation

3
WARNING: Make sure the inverter is clean and no electrical
connection before installation.
WARNING: Make sure there is enough heat dissipation space for
the inverter installation, and do not install the inverter in humid,
greasy, flammable, explosive, dust accumulative or other severe
environments.
6. Safety cautions for electrical connection
CAUTION: To avoid the danger of heat accumulation caused by
the loose connection, please ensure all the cable connections are
tight.
CAUTION: Please connect the inverter case to the ground and
ensure the sectional area of the connection cable is not less than
4mm2.
CAUTION: Follow the parameter setting requirements to set the
DC input voltage, higher or lower may cause the inverter down or even
broken.
CAUTION: The cable between battery and inverter should be less
than 3meters, otherwise, please reduce the current density.
CAUTION: A fuse or breaker is recommended between battery
and inverter, also the rated current of the fuse or breaker should be
two times of the inverter rated input current.
CAUTION: Keep the inverter away from the flooded lead-acid
battery because the sparkle of the terminals may ignite the hydrogen
released by the battery.
WARNING: Only the load is allowed to connect to the AC output
terminal, do NOT connect it to power supply or utility, which may
cause the inverter damaged, also please shut off the inverter before
wiring.
WARNING：Do NOT directly connect the battery charger or
similar devices to the input terminal of the inverter.

7.Safety cautions for inverter operation
WARNING HOT SURFACE: Do NOT touch the inverter when it’s
operating, the inverter case of the inverter will generate a high value of
heat, also keep distance to the material or equipment affected by high
temperature.
CAUTION: Do NOT open the inverter external case or try any
operation when the inverter is ON.
WARNING: The AC output with high voltage during the inverter
operation, do NOT touch any connection point, it may cause danger.
8.The dangerous operations which would cause electric arc, fire or
explosion
Touch the wire end, which hasn’t been insulation treated, may cause
electric shock.
Touch the wiring copper row, terminals or internal devices, which may
cause electric shock.
The power cable connection is loose.
Screw or other components inadvertently falls into the inverter.
Incorrect operation by untrained non-professional people.
WARNING: When a fault occurs, please ask trained technicians
to solve the issue. Any incorrect operation would cause a serious
accident.
9. Safety cautions for shutting off the inverter
The internal conductive devices are allowed to touch after the inverter
has been shut off completely for ten minutes.
The inverter is allowed to restart after removing the fault which affects
the safety performance of the inverter.
No maintenance parts are included in the inverter, please contact our
customer service department for required maintenance service.

5
WARNING：Do NOT touch or open the external case before the
device is shut off completely for ten minutes.
10. Safety cautions for inverter maintenance
Testing equipment recommend to check the inverter without voltage or
current;
During installation and maintenance, please post temporary warning
signs or put up roadblocks to prevent unrelated people from entering
the area.
Improper maintenance operations to the inverter may cause personal
injury or equipment damage.
To prevent electrostatic damage, please wear an antistatic wrist strap
or avoid unnecessary contact with the circuit board.

6. Installation instructions
6.1General installation notes
Please read the manual carefully to get familiar with the installation
steps before installation.
Be very careful when installing the batteries, especially flooded
lead-acid batteries. Please wear eye protection, and have fresh water
available to rinse if any contact with battery acid.
Keep the battery away from any metal objects, which may cause a short
circuit of the battery.
Loose connections and corroded wires may result in high heat that can
melt wire insulation, burn surrounding materials, or even cause a fire.
Ensure tight connections and use cable clamps to secure cables and
prevent them from swaying in motion.
Please follow the parameter list to connect the DC input, even though
the inverter has a high range of DC input voltages. Too high or too low
may cause the inverter to stop working, even damage the inverter
(Surge voltage less than 20V for 12V system, 40V for 24V system,
80V for 48V system)
Select the system connection cables according to the current density no
higher than 3.5A/mm2.(In accordance with the National Electrical Code
Article 690, NFPA70).
For outdoor installation, keep out of the direct sunshine and rain
infiltration.
High voltage still exists inside the inverter after turning off the switch, do
not open or touch the internal devices, wait ten minutes before
conducting related operations.
Please do not install the inverter in humid, greasy, flammable, explosive,
dust accumulative, or other severe environments.
AC output is a high voltage, and please do not touch the wiring
connection.
When the fan is working, and please do not touch it to avoid injury.

IMPORTANT: The wire size and terminal are for reference only,
use thicker wires to lower the voltage drop, and improve the system
performance when the distance between inverter and batter is far.
IMPORTANT: The above wire size and circuit breaker size are for
recommendation only, please choose suitable wire and circuit breaker
according to the practical situation.
6.3 Mounting
Installation steps：
Step1：Professional personnel read this manual carefully.
Step2：Determination of installation location and heat-dissipation space.

17
IMPORTANT: The inverter shall be installed in a place with
sufficient airflow through the dissipation pad of the inverter and a
minimum clearance of 150mm from the upper and lower edges of the
inverter to ensure natural thermal convection.
CAUTION: The inverter shall be cooling through case if installed
in a closed box.
IP1500-12-Plus/IP2000-**-Plus
IP3000-12-Plus
Step3：Wiring
WARNING：The AC equipment shall be determined by the
continuous output power of the inverter, but the surge power must be
lower than the instantaneous surge power of the inverter.
CAUTION: The switch of the inverter isOFF before wiring.
CAUTION: DO NOT close the circuit breaker or fuse and make
sure that the leads of “+” and “-”poles are correctly connected while
wiring the inverter.
