3. Safety

Any work on the Batteries should be handled by authorized technicians and hence it is understood that the technicians should familiarize themselves with the contents of this manual before any maintenance or installation is carried out on the system.

3.1 Handling

· Do not expose battery to open flame.
· Do not place the product under direct sunlight.
· Do not place the product near flammable materials. It may lead to fire or explosion in case of
accident.
· Store in a cool and dry place with ample ventilation.
· Do not store the product near water sources.
· Store the product on a flat surface.
· Store the product out of reach of children and animals.
· Do not damage the unit by dropping, deforming, impacting, cutting or penetrating with a sharp object.
It may cause leakage of electrolyte or fire.
· Do not touch any liquid spilled from the product. There is a risk of electric shock or damage to skin.
· Always handle the battery wearing the insulated gloves.
· Do not step on the product or place any foreign objects on it. This can result in damage.
· Do not charge or discharge damaged battery.
· Do not store the battery near water sources.

3.2 Installation

· Do not connect the ECS to inverter conductors or Photo-Voltaic conductors. This will damage the
battery and may result in explosion.
· After unpacking, please check the product for damages and missing parts.
· Make sure that the inverter and battery is completely turned off before commencing installation.
· Do not interchange the positive and negative terminals of the battery.
· Ensure that there is no short circuit of the terminals or with any external device.
· Do not exceed the battery voltage rating of the inverter.
· Do not connect the battery to any incompatible inverter.
· Do not connect different battery types together.
· Please ensure that all the batteries are grounded properly.
· Do not open the battery to repair or disassemble. Only FOXESS is allowed to carry out any such
repairs.
· In case of fire, use only dry powder fire extinguisher. Liquid extinguishers should not be used.
· Install the batteries only inside approved FOXESS enclosure. Installing the battery anywhere outside
is strictly forbidden.
· Do not install the battery near water sources or places where the battery can get wet.
· Install the battery away from children or pets.
· Do not use battery in high static environment where the protection device might be damaged.
· Do not install with other batteries or cells.
· Please ensure on installation site that the deviation of voltages between new batteries and every
single present battery is less than 0.5V.
· Please ensure the new batteries mounted on-site comply to the warranty scope or have ever been
re-charged within 5 months; on top of that, please make sure the SOC of present battery system onsite is 50%±5%.

4. Response to Emergency Situations

The batteries comprise of multiple batteries connected in series. It is designed to prevent hazards or failures. However, FOXESS cannot guarantee their absolute safety. Under exposure to the internal materials of the battery the following recommendations should be carried out by the user.
· If there has been inhalation, please leave the contaminated area immediately and seek medical
attention.
· If there has been contact with eyes, rinse the eyes with running water for 15 minutes and seek
medical attention immediately.
3
· If there has been contact with the skin, wash the contacted area with soap thoroughly and seek

· If there has been ingestion, induce vomiting and seek medical attention.
Fire Situation
In situations where the battery is on fire, if it is safe to do so, disconnect the battery pack by turn off the circuit breaker to shut off the power to the system. Use FM-200 or Co2 fire extinguisher for the battery and an ABC fire extinguisher for the other parts of the system. Under any fire situation, please evacuate the people from the building immediately before trying to extinguish it.
Water Situation
The battery modules are not water resistant. Hence care should be taken not to get it wet. If you find the battery completely or partially submerged in water do not try to open. Contact an authorized personnel or Fox for further instructions.

5. Product Information

1. CS is the battery module, and CM includes system controller and battery module;
2. CM contains the controller of the entire system, so each system must have one CM;
3. Our system consists of at least 1 CM+1 CS and up to 1 CM+6 CS.
4. Only ECS4000 can be used in the US market and the max battery system consists of 1CM+4CS.

10. Troubleshooting and Maintenance

10.1 Maintenance

A. Regularly check whether the service environment of the battery meets the requirements, and the
installation position should be far away from the heat source.
B. The battery module should be stored in an environment with a temperature range between -20℃-
+55℃, and charged regularly according to the table below with no more than 0.5 C(A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity.) to the SOC of 50% after a long time of storage.
C. Regularly check whether the battery and its supporting terminals, connecting cables and indicator
lights are normal.
28

10.2 Troubleshooting

When the red / green LED on the panel is flashing or normally on, it does not mean that the CS is abnormal, it may be just an alarm or protection. Please check the ‘LED status indicators’ in chapter 7 for the detailed faulty definition before any trouble-shooting steps. In general, the alarm indication is normal without manual intervention. When the alarm triggering state is removed, CS will automatically return to normal use.
- Problem determination based on the following points
1) Whether the green light on the power switch is on;
2) Whether the buzzer in CM on;
3) Whether the battery system can be communicated with inverter;
4) Whether the battery can be output voltage or not.
- Preliminary determination steps
Battery system cannot work, when DC switch on and POWER on, the LED doesn’t light up or flash, please consider contact the local distributor.
1) The LED display of CM and CS is normal, but it cannot charge and discharge. Observe the display screen of inverter and there is no SOC. Please check whether the CAN communication between CM to inverter is well connected. If the connection is good, please replace a CAN communication cable. If the SOC is still not visible on the inverter display screen, please contact the local distributor.
2) After the battery system is powered on, if you can see the alarm information on the LED and inverter display screen at the same time, please contact the local distributor.
