3.2 Safety Instructions and Notice for Use
The inverters involved in this manual comply with applicable safety and
technical regulations in design and test. To avoid personal injury and property
damage and to ensure longer service life of the machines, please read this
manual carefully and observe all safety information during operation.
Improper operation may result in risk of person injury or damage to the
machine and to other property, so please ensure that the following
requirements are met before or during operation.
Installation of inverters must be performed by qualified technicians, and
be in compliance with applicable electrical standards, regulations and the
requirements of local power authorities.
Wear protective equipment for all work on the machines: helmet,
insulated footwear, gloves, etc.
Ensure that unauthorized persons and children have no access to the
machines.
Do not open the housing of the machines at any time. Unauthorized
opening will void guarantee and warranty and may damage the
machines.
Do not touch non-insulated parts or cables, disconnect the machines
from voltage sources and guarantee no possible re-connection before
working on the machine.
Use measuring devices with a DC input voltage range of 600 V or higher
only.
High voltage is present in the live parts and cables inside the product
during operation, wait at least 5 minutes after disconnecting voltage
sources.
The temperature of some parts of the inverter may exceed 60 ℃during
operation. To avoid being burnt, do not touch the inverter during
operation.
Pack inverters properly during transportation, and do not transport them
together with flammable material.
the inverters are to be installed in single phase circuit and should not be
installed in multiple phase combinations.

4.1 Installation Location
WARNING
Do not select locations storing flammable material which may cause fire
or explosion!

9
10
The following points should be considered when selecting an installation
location.
The wall bearing inverters shall be able to hold the weight of at least 4
times of the weight of the inverters.
The location shall be convenient for electrical connection, operation and
maintenance.
The ingress protection of the inverter is IP66, so it can be installed both
indoors and outdoors.
The temperature of the cooling fin may exceed 75 ℃, so select safe
locations.
The location must be well ventilated and sheltered from direct sunlight,
rain or snow.
Ensure the visibility of the LED lights and LCD display on the front panel
of inverters.
Install inverters vertically or with a backward tilt within 15 degrees. No
lateral tilt is allowed.
If more than one inverter are installed in one location, a minimum 150
mm clearance should be kept between two inverters and a minimum 300
mm clearance between inverters and the ground.
The Inverter is to be installed in a high traffic area where the fault is likely
to be seen.
4.2 Inverter Mounting
Dimension of the mounting bracket:
Unit: mm
Procedures:
1) Ensure that the bracket is horizontal. Mark the position of the drill holes.
For brick walls, the position of the holes should suit expansion screws.
2) Use a 10 mm drill bit to drill mounting holes of 40 mm deep.
3) Insert the expansion tubes into holes.
4) Screw the expansion screws into expansion tubes with a cross
screwdriver to fix the bracket on the wall.
5) Lift up the inverter, and hang it on the mounting bracket securely.
6) Lock the inverter to the mounting bracket with screws.
NOTE: To protect your hands from scratch, please wear gloves!

5. Electrical Connection
5.1 DC Side Connection of Inverters
PV strings should be connected to the inverter through special PV connectors
that are in the scope of delivery.
It is recommended to use the DC cable of 4 or 6 mm2.
Assemble DC cables to DC connectors:
1) Strip the insulation layer off the DC Cable for about 7mm.
2) Insert the wire into the Crimp Contact and crimp them with an electrical
crimp-er.
3) Thread the cable through the Cable Gland, insert it into the insulator, and
gently pull backward the cable to ensure firm connection. Then screw up
the Cable Gland to the Insulator.
Install the DC connectors to the Inverter:
1) Turn the Grid Supply Main Switch OFF.
2) Turn the DC switch OFF.
3) Connect the DC connectors to the Inverter, small click confirms
connection. Please guarantee the correct polarity of the connection.
DANGER ELECTRICAL SHOCK
Lethal high voltage will be generated by PV arrays under sunlight, so
please disconnect DC and AC breakers and ensure no possibility of
re-connection before conduct electrical connection!
WARNING
Ensure that the open circuit voltage of PV array is within the max. input
voltage of the inverter!
NOTE: Use DC cables specialized for photovoltaic systems Only!
WARNING:Do not turn off DC switch directly for accident reverse
connection of DC inputs or any fault of inverters as it may damage
inverters. In that case, turn off the DC switch only when the DC current is
below 0.5 A.
NOTE: Use only the supplied connector or the connector with IP 65
or above to guarantee that the protection ingress of the whole inverter is
IP66!

5.2 AC Side Connection of Inverters
When connecting an inverter to the utility grid, please use 4 – 6 mm² outdoor
cable. For Each energy 3 KW to 4 KW inverters, it is recommended to use 4
mm² cable, and for 5 KW to 6 KW inverters, use 6 mm² cable.
An AC Connector is supplied together with the inverter.
AC Connector
Procedures:
1) Strip the insulation layer off the AC cable about 8 to 15 mm.
2) Thread the AC cable through the Cable Gland and the Housing.
3) Connect wires to the Terminal Block:
insert yellow green wire to the grounding (PE) terminal, red or brown
to live line (L) terminal and blue or black to zero line (N) terminal;
screw up screws on the connectors with socket head wrench and pull
back wires to ensure firm connection.
4) Connect the Cable Gland, Seal Ring, Housing and Terminal Block together,
a small click confirms secure connection.
5) Connect the AC connector to the inverter, a small click confirms
connection.
5.3 External Grounding Connection
The external grounding port is located beside the AC connection terminal of
the inverter.
Procedures：
Prepare an OT terminal M4, crimp a grounding cable to the terminal, insert a
fastening screw into the OT terminal, insert them to the grounding port on
the inverter, and screw them tightly (the torque is 2 N.m.).
WARNING: The external grounding connection cannot replace
the connection of PE terminal in AC connection. Ensure that both the
external grounding connection and the PE connection are done properly!

5.4 Earth Fault Alarm
The inverters are designed with an earth fault alarm function. If an earth fault
occurs, the inverters will stop generating power, the red alarm light will be on
and the LCD will display ‘ISO Out Range’ or ‘PEN No Connect’. In that case,
please refers to Chapter 7 for troubleshooting or contact Each Energy for
help.
5.5 Over Current Protection Device
It is recommended to install a breaker (over current protection device (OCPD))
to protect the AC grid connection conductors. The table below is the
recommended parameter of an OCPD ratings for the Inverter.
5.6 Communications Connection
