G5040-48
1. It is strictly prohibited to put the battery in water or fire, so as to avoid ex-plosion or other
dangers and endanger personal safety;
2. Please connect the wires correctly during installation. Do not connect the positive and
negative poles reversed. Do not connect lithium batteries in series；
3. Do not puncture the battery by needling, hammering, trampling or other means；
4. Before installing or removing the equipment, ensure that the power system is not live and
that the battery equipment is turned off;
5. In case of fire, please inform the fire department immediately and use lithi-um battery fire
extinguishers that meet the national regulation to put out the fire;
6. If the battery is improperly lifted or dropped while being removed during transportation, it
can cause personal injury;
7. Do not disassemble any part of the system without permission of the Com-pany or the
technical personnel authorized by the Company, in order to pre-vent danger or injury to your
personal safety, and the equipment failure caused thereby is not covered by the warranty.
During standard operation, no electrolyte shall leak from the battery pack and no toxic gases
shall form. Despite careful construction, if the Battery Pack is damaged or a fault occurs, it
may be caused by electrolyte leakage or the formation of toxic gas .
Do not install the system in any environment of temperature below -10°C or over 50°C and in
which humidity is over 85%.
Do not touch the system with wet hands.
Do not put any heavy objects on top of the system.
Do not damage the system with sharp objects.
Do not install or operate the system in potentially explosive atmospheres or areas with high
humidity.
Do not mount the inverter and the battery pack in areas containing highly flammable materials
or gases.
If moisture has penetrated the system (E.g. due to a damaged enclosure), do not install or
operate the system.
Do not move the system when it is already connected with battery modules.
Use restraint strap fixing the battery to prevent tipping during transporta-tion
The transportation of GTE battery must be made by the manufacturer or an instructed
personal. These instructions shall be recorded and repeated.
A certified NOVEC 1230 and FM-200, or CO2 fire extinguisher with a minimum capacity of 2kg
must be carried。
Don't smoke near the vehicle.
If you want to replace the battery module, please pack it according to new packaging,
dangerous goods and packaging suppliers to receive it.
In case of contact with the electrolyte, flush the affected area with clean water immediately
and consult doctor immediately.

2. Battery Storage
3. Installation
3.1 Parts List
Batteries that have been stored for more than 6 months should be recharged be-cause long-term
storage can lead to loss of capacity.
After 12 months of storage at the recommended temperature, the irreversible ca-pacity loss rate of
lithium batteries is 3%~10%, so it is not recommended to store the batteries for a long time without
using them.
It is recommended to charge batteries at least every six months and to charge bat-teries to at least
50% each time.
If the storage time of the battery is more than 6 months, the batteries should be charged to 65~75%.
Check the following parts list and make sure there is no part missing.

3.5 Installation of the Battery
3.5.1 Installation Site and Environment
3.5.2 Unpacking the Box
This manual describes the basic steps of how to install and setting.
The following location are not allowed for installation:：
• Sites with humidity above 85%, or where there is condensation;
• Sites which are salty and where humid air can penetrate;
• Flooded areas.
• Earthquake areas –additional safety measures are required;
• Sites with explosive atmosphere;
• Sites with direct sunlight;
• Sites with extreme change of ambient temperature;
• S ites with highly flammable materials or gases;
• Sites with a potentially explosive atmosphere.
• Sites where the altitude is above 2000 m.
Take out the battery from the packing box and check whether the accessories are complete, as
shown in Figure 2.
When the protection code appears, the battery is still in normal working mode. Once the condition
that triggers the protection is removed, the battery will automati-cally resume work.
If the protection code 09 appears in the working mode, please press the power but-ton 5 times
within 10 seconds, the BMS will be forced to turn on the MOSFET of dis-charge so that the inverter
can charge the battery.
Giter does not assume any direct or indirect responsibility for any product damage or property
loss caused by the following conditions.

3.5.3 Installation and Wiring
The following work should be completed before wiring:
1. Ensure that the power button of all batteries is OFF;
2. Cut off all relevant power supply equipment.
1. The batteries can not be connected in series.
2. Max. 6 batteries can be connected in parallel.；
3. Connect batteries with cooper bar, and the fixed torque is 5N.m
4. Cables used to connect the battery and inverter should at least meet AWG 2, and can also
withstand temperatures above 105℃and DC voltage above 1000V.
5. The grounding resistance should be less than 1Ω.
Note
Only 3 batteries can be installed in a single row.
Step 1: As shown in Figure 3, fix the hangers on both sides of the battery with 10 screws (M4*8)
respectively.(Torque: 1.6 Nm; Tools: T20 screwdriver).
Step 2: As shown in Figure 4, put the battery into the cabinet (connect the grounding wire in
advance). Tighten the screws (M6*12) and fix the cooper bars between the batteries with 2# cross
screwdriver (Torque: 5 Nm).
（Accessories should be purchased separately）
As shown in Figure 5, stack the batteries on the base one by one to ensure that the batteries are
flush in the horizontal and vertical directions; then use M4X12 screws to fix the limit board
(35x100mm) on both sides of the battery (Torque: 1.6Nm; Tool: T20 screwdriver).
