USER MANUAL

3.1.4 Technical preparation Electrical interface check
Devices that can be connected directly to the battery can be user equipment, power supplies, or other power supplies.  Confirm whether the user's PV power generation equipment, power supply or other power supply equipment has a DC output interface, and measure whether the DC power output voltage meets the voltage range requirements in Table 2-2.  Confirm that the maximum discharge current capability of the DC power interface of the user's photovoltaic power generation equipment, power supply or other power supply equipment should be higher than the maximum charging current of the products used in Table 2-2. If the maximum discharge capacity of the DC power interface of the user's photovoltaic power generation equipment is less than the maximum charging current of the products used in Table 2-2, the DC power interface of the user's photovoltaic power generation equipment shall have a current limiting function to ensure the normal operation of the user's equipment.  Verify that the maximum operating current of the battery-powered user equipment (inverter DC input) should be less than the maximum discharge current of the products used in Table 2-2.
The security check
 Firefighting equipment should be provided near the product, such as portable dry powder fire extinguisher.  Automatic fire fighting system shall be provided for the case where necessary.  No flammable, explosive and other dangerous materials are placed beside the battery.
3.1.5 Unpacking inspection
 When the equipment arrives at the installation site, loading and unloading should be carried out according to the rules and regulations, to prevent from being exposed to sun and rain.  Before unpacking, the total number of packages shall be indicated according to the shipping list attached to each package, and the case shall be checked for good condition.  In the process of unpacking, handle with care and protect the surface coating of the object.  Open the package, the installation personnel should read the technical documents, verify the list, according to the configuration table and packing list, ensure objects are complete and intact, if the internal packing is damaged, should be examined and recorded in detail.

4. Installation and Configuration
4.1 Battery system usage and operation instructions
After completing the electrical installation, follow these steps to start the battery system. 1. Open the BMS on/off, wait the screen open and show battery with normal status. 2. After the LCD screen show battery with normal status, open the air switch.
1. After pressing the power button, if the LCD screen show battery with ALM status, please refer to the "4.2 Alarm description and processing ". If the failure cannot be eliminated, please contact the dealer timely. 2. Use a voltmeter to measure whether the voltage of the circuit breaker battery access terminal is higher than48V*N, and check whether the voltage polarity is consistent with the inverter input polarity. If the circuit breaker battery input terminal has a voltage output and is greater than 48V*N, then the battery begun to work normally. 3. After confirming that the battery output voltage and polarity are correct, turn on the inverter, close the circuit breaker. 4. Check if the indicator of the inverter and battery connection (communication indicator and battery access status indicator) is normal. If it is normal, successfully complete the connection between the battery and the inverter. If the indicator light is abnormal, please refer to the inverter manual for the cause
