Electrical hazard!

The charging station must be installed, commissioned and repaired by a properly trained, qualified and authorized electrician who has full responsibility for compliance with current standards and installation regulations. Please note that vehicle or national regulations may require additional overvoltage protection. For details, please check your local connection and installation standards for reference. Before testing the equipment, please check that all the screws and terminals are firmly connected. The terminal cover shall not be opened without supervision. Before leaving the charging station, fix the terminal cover. Do not make any unauthorized modification or adjustment to the charging station. Repair or replacement of charging station is only to be completed by the manufacturer or trained person. Do not remove any identifiers, such as safety signs, warning instructions, nameplates, labels, or cable marks. Charging Station not equipped with power switch. The residual current action circuit breaker and the building insulation circuit breaker should be used as a power isolation device. Remove the charging cable from the connector through the plug handle, do not pull the cable. Be sure that the charging cable is not mechanically damaged

(kinked, stuck, or crushed). Keep away from heat sources, dirt, or water in the contact area. Do not use this product if the power cord or EV cable is worn, intermediately insulated or any other signs of damage. Do not use this product if the housing or EV connector is 1 broken, cracked, opened, or shows any other signs of damage. Do not leave when using the device if children are nearby. Do not stick objects into the EV connector. Do not use high pressure water (hose, pressure washer, etc.) to clean the charging station! Be sure that the charging station is not damaged by improper handling (housing cover, internal parts, etc.). For charging station installed outdoors, do not open the wiring cover in rain or snow. The installation area must be flat and shall not distort the housing

(enclosure), and the screw torque shall be used at the required value. Touching the electronic components may cause damage. Before touching the module, discharge by touching a metal ground object. Failure to operate with safety instructions may cause personal injuries and equipment damage. The equipment manufacturer is not liable for any claims arising therefrom. 1.2 Device Use The charging station is used to charge electric vehicles or plug-in hybrids for both indoor and outdoor use. Do not use the charging station to connect to any other equipment, such as power tools. The charging station shall be mounted on the walls or cylinders. Installation of the charging station must comply to relevant local specifications and requirements. The use of the equipment for set purposes shall meet the environmental conditions set at the time of development. The development, production, testing, and documentation of the charging station shall be based on the relevant safety standards. If being operated in accordance with instruction and specified purpose, this product will not cause any danger to personal health and property under normal circumstances. The equipment must be grounded. If a problem occurs, grounding helps 2 to reduce the risk of electric shock. The equipment is connected to the grounded metal permanent wire wiring system, or the equipment ground conductor must run with the circuit conductor and be connected to the equipment ground terminal or lead on the product. Please carefully follow the instructions outlined in this manual. Otherwise, a potential hazard may occur or the safety equipment may become inoperable. In addition to the safety information described in this manual, please review specific equipment specified in the Safety and Accident Prevention Code. 1.3 About this manual This manual is designed for trained personnel. Such personnel specifically refer to those who have been trained by relevant standards, acquired relevant skills, experience and knowledge, also can conduct assigned operations and identify potential dangers. Please read the operation manual for operation information and instructions for the device. 3 1.4 Packaging and accessories 4 2 .Contents Overview 5 3. Installation Specifications 3.1 General Criteria for Installation The charging station can be used either indoors or outdoors. Therefore, it is necessary to ensure that the installation site meets the required conditions and certain protective measures are taken. Refer to local electrical installation regulations, fire prevention regulations, accident prevention regulations, and on-site rescue routes. Do not install charging station at:

-Escape or rescue route.

-Areas with potential explosion hazards (EX environment).

-Environment that causes charging station to contact ammonia. (e.g. restrooms)

-Environment where the charging station may be damaged by falling objects (such as hanging ladders or tools).

-Location in which the charging cable may be a trip hazard for pedestrians.

-Location that may cause the charging station to be subject to high pressure water (e. g., manual car wash system, high pressure washer, or garden hose nearby).

-Installation surface cannot withstand mechanical stress. Wherever possible, Install charging station in areas protected from direct rainfall to avoid damage from weather, ice and hail. Wherever possible, Install in areas protected from direct sunlight to avoid reduced charging current or interruption of charging process due to high temperature. Follow the approved environmental conditions, as described in the

"Technical parameter" section. Ensure compliance with national and international installation standards and specifications. 6 3.2 Electrical Connection Instruction The default current for the charging station is 50A. Ensure that the maximum current is set using the APP to accommodate the installed circuit breaker. Please see details in the Current Setting Up section. Select the power supply cable Only use 90 Copper Core Cable 6AWG / 50A, 8AWG / 32A, 11AWG

/ 16A. It must be permanently connected to the existing building facilities. Wiring terminal is rated to 105 and accepts a maximum of 16 mm2 (6 AWG) wire. Power isolation device The charging station does not have a power switch. The current action circuit breakers and / or power supply cable circuit breakers can be used as power isolation devices(not recommend using a GFCI breakerCCID protection is included in the device). When selecting the circuit breaker, the temperature climb of the control room should also be considered, combined with the required charging rating and the capacity of the power supply cable. 4. Installation 4.1. Installation Requirements Comply with the local installation specifications. Product must be connected to a grounded fixed metal wire wiring system; or the equipment ground conductor must operate with the circuit conductor and connect to the equipment ground terminal or product conductor. Environmental adaptation: If the temperature difference between transportation and installation site exceeds 15, the charging station must keep unopened for at least two hours. Immediate opening may cause condensation within the charging station and my cause damage when opening the device. In some cases, damage caused by condensation may not appear immediately after installation 7 but will be exposed after some time. Ideally, the charging station should be stored on the installation site for several hours before starting the installation. Even if this condition cannot be met, the charging station should not be placed outside or inside the car at low temperature (<5). Ensure there is WIFI signal available. The APP requires a wireless connection to use. List of tools Electric Drill (Brick wall only) Phillips / Cross #2 screwdriver Flat Tip #0 screwdriver Marking pen or pencil 4.2 Recommended Installation Location Before installing, check the site for mounting location and electrical capacity.
