1.2 Safety Instructions
For safety reasons, installers are responsible for familiarizing themselves with the contents of this
document and all warnings before performing installation.
1) During the operation and maintenance of this product, please wear appropriate personal
protective equipment (PPE) in accordance with the operating regulations of high voltage DC
power supply and take good personal protection. If you need to handle the battery directly,
please wear insulated rubber gloves.
2) During transportation, do not pierce or bump the power system product, or expose it to open
flames or incineration. In case of fire, do not rinse with water. Use dry powder fire extinguisher
to extinguish any fire.
3) To avoid injury, burns, or electric shock, keep children away from the product.
4) Before touching the battery or power system, remove personal items containing metal (such as
watches and rings).
5) To prevent the build-up of static electricity, service personnel should touch large grounded
metal parts before operating the battery.
6) When climbing during maintenance, pay attention to safety to prevent people from falling or
batteries from falling.
7) When connecting high-voltage power cords, use insulated tools and suitable insulating
materials.
8) Never place tools or metal parts on top of the battery.
9) During the assembly process, please be careful not to touch the positive and negative terminals
of the battery system with your hands or other metal objects at the same time to avoid electric
shock or short circuit.
10) Do not step on or sit on the power system.
11) Do not reverse the positive and negative poles of the power system, otherwise it will cause
reverse charging, which will cause the battery to leak, heat and rupture.
12) Do not open or modify the battery in any way. Any electrolyte flowing out of the battery may
damage the skin and eyes. If electrolyte exposure occurs, please wash it with plenty of water
repeatedly and seek medical attention.
13) It is strictly forbidden to modify the power supply system without authorization. In order to
prevent danger, a protection system is installed in the power supply system. If the protection
system is damaged, the charging may not be controlled, or the charging and discharging current
may exceed safety limits, resulting in battery leakage, heat generation and damage to the
battery.

optimal ambient temperature of 5 to 35 °C, and store at the optimal ambient temperature of 0 to
30°C.
17) Avoid overcharging the power supply for a long time, otherwise the battery will leak.
18) When a power system product reaches its end-of-life or is discarded, it should be disposed of in
accordance with national or local regulations and must not be discarded at will.
19) If the product develops a fault or displays abnormal behavior, immediately disconnect the
power by following the shutdown procedure and contact the supplier for repair.
20) During installation of the battery, the utility grid and solar input must be disconnected from the
Battery system wiring. Wiring must be carried out by qualified personnel.
Caveat
Only suitably qualified professionals can perform this assembly and installation of this System!
Do not disconnect, disassemble or repair any part of this System unless you are suitably qualified.
Services must be undertaken by qualified personnel only.
Observe all warnings and cautions! Ignoring the safety warnings can result in serious personal
injury or death!
If the power system is charging and discharging, if there is an unusual smell or sound, stop charging
immediately and contact the supplier!
Store the product out of reach of children and animals.
Do not store this product in a place exposed to direct sunlight.
1.3 Response to Emergency Situations
1.3.1 Battery Leakage
If the battery system electrolyte leaks, avoid contact with the leaked liquid or gas. If the user is exposed to
the leaked material, immediately deal with it as described below:

5.6.1 Example wiring diagram of single battery system into a cabinet
Figure 10 Cabinet wiring diagram.
Steps:
1) First, insert the positive plug of the Positive Battery Cable into the corresponding socket on the
Battery Module, then connect the other end to the battery side of the D.C. isolating switch a.
Connect the negative plug of the Negative Battery Cable into the negative socket on the Battery
and then connect the other end to the D.C. isolating switch b.
2) Take out the communication cable, install it as shown in Figure 10, connect it to the communication
port on the right side of the cabinet, and then use RJ45 to connect it to the PCS (inverter)
communication port.
3) Use the M6 x 6mm pan head screw to fix one end of the ground wire of the pressed terminal at the
grounding screw, and the other end is connected to the grounding copper bar such as figure 11.
4) The ground wire of PCS or combiner box, etc. is connected to the external grounding copper bar.
Note
Before wiring, the switch on the cabinet shall be in the off state.
Before the positive wire and negative wire are connected to the system, any exposed conductor
part needs to be wrapped with insulating tape to prevent short circuit.
The D.C. Isolating switch and external copper bar are not shipped with the battery system. If
necessary, contact ZNTECH or an Authorized Reseller in the Territory
This unit is not suitable for outdoor installation. An Outdoor Cabinet is not offered by

MANUAL NAME: LBB051100A Residential Energy Storage Box User Manual REV NO..: V1.2
Date: November 4, 2019
ZHONGNENG TECHNOLOGY (HANGZHOU) CO., LTD
19
ZNTECH. If necessary, contact ZNTECH or an Authorized Reseller in the Territory
The number of parallel battery systems affects the current. The following is a list of parameter
descriptions about the selection of circuit breakers (for reference only).
If a battery or batteries are mounted inside a cabinet, the cabinet should be suitably identified and
marked to include information such as (but not limited to) battery identification, capacity, IP rating
and any and all requirements of any relevant Standards.
5.7 Use of D.C. isolating Switch
Each battery system is connected to a D.C. isolating switch with the appropriate voltage and current to ensure
that the system is secure. The recommended D.C. isolating switch is Nader DC80V, 63A DC D.C. isolating
switch. The reference figure is as follows:
Figure11 Schematic diagram of D.C. isolating switch
The system current changes after different Numbers of packs are connected in parallel, and the current is
generally larger than one single pack. The selection of switches connected to PCS should be based on the
maximum battery current decided by the PCS or the actual working current. If the D.C. switch is not suitable,
then a circuit breaker can be considered.
Note
The D.C. isolating switch shall be selected by the customer. If necessary, contact ZNTECH or
an Authorized Reseller in the Territory
During the transportation and storage of the battery, the switch shall be disconnected to protect
the battery and make it safe.
6. Instructions for Use
