installation requirements of the charger. Fix the charger on the channel steel or
foundation with the M12 screw through the lumbar hole in the base .The fixing
method is as follows:
2、Pull the power cable from the power distribution cabinet to the
base of the charger, install the charger on the base, you will find
bolts for the fixed mounting holes at the four corners of the base
of the cabinet. Fix the pads and nuts with the adjustable wrenches.
Fix charger on the base, the installation sequence shows below.

3、Open the front and back door with the key, take off the protective cover, and pull
the incoming cable through the base to the charger. Pull it to the end of the incoming
cable row.
4 、 Connecting the power cable to the incoming terminal block
(incoming copper busbar) using a screwdriver (wrench) firmly
connected with the corresponding (yellow, green, red to FireWire,
black to neutral grounding wire, grounding line to grounding copper
busbar)：
L1(Yellow)/L2(Green)/L3(Red)：firewire: N(Black)：Neutral: PE(Grounding
busbar)：Grounding wire
 5、Switch on the upper power supply switch of the charger, using the multimeter
to detect whether the connection of the incoming firewire, neutral wire and
the ground wire of the power supply is correct, and if there is no mistake,
the main switch of the charger can be switch on to power the charger
6、Tidy up the cable, turn off the charging cabinet door, plug the gun into
the equipment socket on the side of the cabinet

the card is swiped successfully;

Step 5: After swiping the card successfully, the auxiliary power

selection box will pop up, and 12V or 24V can be selected as
required; (Note: the selection is only applicable to the national
standard, not to the European standard)
Step 6: When fully charged, the charger will automatically stop
charging. During charging, you can also click the "End charge"
button to stop charging

Step 7: Put the gun back

3.2 Networking Settings
Step 1: come to the following main interface；

Step 2: click "setting" in the main interface, and the following dialog
will pop up. Enter "Users" in the user name and password "888888";
Click "OK" after setting;
 Step 3: Enter the following interface and set according to the
actual requirement: for example, "IP address" and "port number"
should be set according to the actual background; "Device ID" should
be set according to the cabinet number; "BMS protocol selection"
should be set according to the "15 national standard" or "European
standard", and "background setting" should be set according to the
actual needs or other settings.

4. Loading, disassembly and storage

4.1 Loading and disassembly
When handling and lifting the package, the center of gravity of
the packing box must be paid attention to in order to avoid the tipping
of the package. Unpacking is only allowed onsite！
Before unpacking, check whether any of the package is damaged
during transportation. If the packaging shows signs of damage, it
should be in the presence of the logistics company personnel to
unpacking and inspecting the equipment. External damage must be
recorded immediately in the transport document! When unpacking,
unpacking carefully, and don't use sharp tools to prevent damage to
the shell. Damage found after unpacking must be reported to the
logistics company and the manufacturer within one week！
The manufacturer will not be responsible for the failure to
receive the damage report! If the equipment is damaged during
transportation, please follow the following steps:
 Take photos of damaged parts
 Return the report and photos of the damaged equipment to the
transport company and send a copy back to the transport company
4.2 Storage

 The equipment must be stored in a clean, dry and dust-proof

environment with its original packaging.
 must always be stored up!
 Storage period is 1 year
 During storage period, storage environment must always meet the
following conditions:
 Relative humidity: 5%～85%
 The fire extinguishing equipment and materials required for such
warehouses are equipped and in good condition.
 Keep the storage area clean at all times, and there must be no
accumulation of waste and waste packaging materials.
 In order to avoid damage or dirty to equipment, must prevent small
 animal and insect into the storage area.
 In order to minimize the risk of equipment damage, it is necessary
to consider the convenience of inspection and maintenance when
storing all equipment. When the equipment is stacked, the ability
of the lower layer to withstand the gravity of the upper layer
must be considered without damage.
5. Maintenance and repair

5.1 Maintenance

 Regularly check whether the ventilation facilities in the place

where the equipment is located are in good condition and whether
the indoor temperature meets the requirements;
 The charger must be protected from strong vibration or exposure
to high temperature and humidity;
 Clean the charger with dry cloth or anti-static cloth. Do not use
chemical or abrasive cleaning agent to avoid damaging the shell;
 When it is not used for a long time, the AC power supply must be
disconnected, and it should be placed in a dry and ventilated place
indoors and covered with a hood. After a period of time, it should
also be electrified to remove moisture;
 During the charging process, the ventilation shutters on the shell
shall not be covered to ensure the timely diffusion of heat
generated in the charger;
 Dust the air inlet, exhaust duct, fan and filter screen once every
three months. It is recommended to remove dust once a week in areas
with severe dust;
 Before checking the charger device, make sure that the AC and DC
side switches of the power supply circuit have been disconnected
and that the DC output voltage is 0V before maintenance;
 After the fuse in the circuit is blown, it must be replaced
according to the required specifications, and it is not allowed
to replace it with a wire;
 It is forbidden to charge non rechargeable batteries;
 No non professional personnel are allowed to enter the operation
room and operate the equipment.
5.2 Trouble shooting

If abnormal situation happens while running, and charger need to

stop to do inspection, following steps must be strictly followed:
 Quickly press the "off" button to stop the charger;
 Disconnect the control power switch, disconnect the main power
switch
 Turn off the main switch power supply (not affecting other
equipment);
 Wait after 10 minutes to open the cabinet door, measure the DC
output voltage with a multimeter, and confirm that the DC output
voltage is 0V then the internal maintenance operation can be
carried out;

 When implement internal maintenance, AC line power

supply must be disconnected, charger and battery
connection line or charging gun disconnect
 After the maintenance is completed, test and
commissioning to confirm the charger is normal before
it can be put into formal operation.
 In the maintenance process, only one person can
！ operate, the other personnel monitor, and the guardian
personnel and the operator need to maintain a certain
distance
 It must be completed by professional engineers to
ensure safety of both personal and equipment!
