Preface:
In order to enable you to use 40kW EV DC charger safely, you can remove it in time
when you encounter a fault, please read the instructions carefully before use.
The charger is suitable for lithium-ion power batteries, providing energy output not
greater than the rated power, and maintaining high output voltage and current
accuracy; the display is the most important man-machine interface for the charger.
Display the state of charge, battery pack status, fault status, etc.
The charger strictly implements IEC 61851-1-2010 (Electric Vehicle Conductive
Charging System-Part 1: General Requirements) DIN SPEC 70121-2014-en (Electric
Vehicle-Hybrid Charging System, Electric Vehicle Charging Station for Controlling DC
Charging Digital communication with electric vehicles)
This manual is only applicable to 40kW series EV DC charger. The content of the
manual will be updated without any notice with the upgrade of control software and
display interface software.
Please keep the instruction manual for future reference.

Operating Conditions and Safety Matters
(1) Operating Environment
Working temperature: -20℃～50℃;
Working Humidity: 5%～95%;
Atmospheric Pressure: 80kPa～110 kPa
(2) Safety Matters Instruction
1) Charger should be operated according to operation instruction provided by Luoyang
Grasen Power Technology Co.,Ltd.
2) Non professionals are forbidden to open charger cabinet and dismantle screen
touch without permission, sharp objects are forbidden to operate on the screen.
3) If there is stop halfway, first click “stop” button manually,then pull out charging
connector. Forbid inserting and pulling out charging connector directly during charging,
otherwise charging connector and charger will be burnt out and even the operators will get
burnt.
4) Any operation irrelevant to charging during the charging is forbidden.Other
operations should be done after clicking “stop” button on the charger and charging connector
disconnects with the vehicle.
5) Under urgent circumstances,press red emergency stop button on the charger and
cut down charger internal power supply.
6) Smoke and fire is forbidden around the charger and pay attention to ventilation.
7) The fuse must be replaced with the same type fuse and can’t be replaced by
copper and iron wire.

8) When there is high voltage or default, it should be repaired by professionals in risk
of danger.
9) Charger upper circuit breaker and power distribution cabinet should be
chosen,installed and operated by professional electricians;
10) It is recommended to turn off the power under severe weather such as
thunderstorm. If there is water accumulation in the charger, please contact the
manufacturer's personnel to deal with it before using it.
11) Charging cable unit weight is heavy,longer cable is easy to drag and under force,
adding the risk of cable twist,bump to and influence product service life. Therefore, pulling
hard and twisting charging cable is forbidden. Charging cable must not be twisted to make
charging socket under force when charging.
12) When inserting or pulling out charging connector, shaking the charging connector
is forbidden and it must insert or pull out with vertical force.
If the following conditions occur,please cut down the power in time and inform the
professionals for maintenance.
Abnormal sound inside the charger
Abnormal sound inside the charger
Abnormal smell or smoke inside the charger
No indication or responsive in charger display screen
An unrecoverable failure alarm in charger
Notice:Before power-on operation, please ensure good connection between device
shell and ground, otherwise there is danger of electric shock.
