1. General Safety Instruction
1.1 Safety Instruction
As dangerous voltages and high temperature exist within the eRay inverter, only qualified and
authorized maintenance personnel are permitted to open and repair it.
This manual contains information concerning the installation and operation of the eRay inverter. All
relevant parts of the manual should be read prior to commencing the installation. Please follow the
local stipulation meantime.
Any operation against safety requirement or against design, manufacture, safety standard, and are
out of the manufacturer warranty.
1.2 General Precaution
1) Do not expose to dust, rain, snow or liquids of any type，it is designed for indoor use. DO NOT
block off ventilation, otherwise the INVERTER would be overheating.
2) To avoid fire and electric shock，make sure all cables selected with right gauge and being
connected well. Smaller diameter and broken cable are not allowed to use.
3) Please do not put any inflammable goods near to inverter.
4) Never place unit directly above batteries, gases from a battery will corrode and damage
inverter/charger.
5) Do not place battery over the inverter.
1.3 Precaution regarding battery operation
1) Use plenty of fresh water to clean in case battery acid contacts skin, clothing, or eyes and
consult with doctor as soon as possible.
2) The battery may generate flammable gas during charging. NEVER smoke or allow a spark or
flame in vicinity of a battery.
3) Do not put the metal tool on the battery, spark and short circuit might lead to explosion.
4) Remove all personal metal items such as rings, bracelets, necklaces, and watches while
working with batteries. Batteries can cause short-circuit current high enough to make metal
melt, and could cause severe burns.

4. Configuration
The dip switch setting function is only available for 1500/2000W model.
Please do the correct configuration for voltage and frequency by dip switch S1 before installing the
inverter.The default factory setting is 230VAC 50Hz.
Also the user can set the power saving mode by dip switch S2.The default factory setting of power
saving is OFF.

Power saving threshold setting value is adjustable by Dip switch S2-2/3/4. Please refer the below
table
When the load is less than the power-saving threshold setting value, the inverter automatically
enters the power saving mode to reduce the static power consumption, thereby saving battery
power.
When the inverter is in power saving, the “inverter” indicator is flashing.
During the period when the inverter is in power saving status, there is a discontinuous output
every 6secs to detect the load status. Please adjust the threshold value if the loads are
powered on shortly by the output.
There is a small gap between the threshold of entering and exiting the power saving mode.
That is to avoid the frequent switch when the load power is close to the threshold value
because of the detecting deviation.

5.3 Wiring + Fuse recommendation
Please find the following minimum wire size. In case of DC cable longer than 3m, please increase
the cross section of cable to reduce the loss.
We recommend connecting a DC fuse corresponding to the conductor between battery and inverter,
which will offer protection to the battery cable. Please refer to following chart of our
recommendations.
On the AC output side, we recommend connecting the output from the inverter to Circuit Breaker.

5.4 Installation and Connection
For the user operation safety, cut off the power before installation
5.4.1 Fix the equipment
Basically, eRay inverter could be installed either vertically on wall or horizontally on floor.
Please choose a flat surface and with M6 to fix the unit securely
In mobile application, please keep the vibration as small as possible
5.4.2 Connecting the cable
Please make sure the inverter is turned off before connection.
Otherwise, high voltage could be present.
Please double check battery voltage match the model you are
going to install, the wrong battery could destroy equipment and is
out of warranty.
Please double confirm the polarity of DC input. Reverse polarity
could cause permanent damage on equipment and it is out of
warranty.
Please ensure that the protective grounding of the chassis is
connected to the ground or the chassis of the vehicle when using
this machine on the application platform of vehicles and ships.

Connecting to earth
At the bottom of the enclosure, there is a ground terminal. Please connect it with EARTH or vehicle
chassis via an 8# AWG wire.
Figure 5-1 Connecting diagram of the ground terminal
Connecting to battery
The installation of a fuse must be on a positive cable. Failure to place a fuse on positive
cable between the inverter and battery may cause damage to the inverter and it is out of
warranty.
Ensure all the battery cables are tight (torque to 12Nm). Loose connections may cause
overheat and fire.
Choose the right cable size (refer to 5.3 for details) and follow polarity guide marked on the
panel.
Pull the positive DC cable through the red plastic cover and negative DC cable through the
black plastic cover.
Insert the cables to the DC input terminals on the rear panel of the inverter. The red terminal is
represents positive (+) and black terminal represents negative (-).
Secure the DC cable on DC input + and DC input - terminals respectively making sure it is tightly
screwed.
Cover the red and black plastic caps on DC + and DC - terminals respectively.

Connecting dry contact input
1) You can use dry contact supplied to switch on/off the inverter through ignition.
2) At anytime, please use only one of them to control the inverter on/off, either main switch or dry
contact.
3) Please find the following two recommended wiring for dry contact input

6. Operation
6.1 Double Checking
Check the DC input voltage of this inverter is same to your battery nominal voltage. NEVER try
to connect different DC input to inverter.
Inspect the right polarity of DC on service battery; otherwise the unit cannot be powered ON.
Please check if you connect the Negative terminal of starter battery to the DC – terminal of
inverter.
Inspect AC output is correct; make sure unit is no short circuit.
6.2 Inverter operation
Press shortly the ON/OFF switch on the front panel to turn the inverter power on. After that the “INV”
and “BATTERY” LED indicators are illuminated, and then the inverter is ready to deliver AC power
to the loads.
The ON/OFF switch, dry contact input and optional remote control works independently. It means if
you use one group switch to power on the inverter, you can only use the same group to power off.
