3.2 Visual Inspection of the Modules
After transporting the modules to the installation location, check for:
 Physical damage to the exterior
 Damaged or protruding screws
4. Battery Installation
This system must be installed by qualified, trained workers familiar with the required instruments.
The battery can be used in indoor environments where the ambient temperature and humidity are not
controlled where the humidity can reach 90%.

▪Be sure to use insulated tools (torque wrench, extension, socket, etc.).
▪All the instruments must be insulated and no metal articles (e.g. watch,
ring) shouldbe present in the installation area.
▪All power switches must be turned off in advance.
▪Prepare a CO2 fire extinguisher, a first aid kit, and an AED (automated
external defibrillator) before installation.
Arc Flash and Shock Hazard
Insulated tools are required for any work on this energizedequipment.
Sharp Edges
Wear gloves and other protective gear to prevent injury.
Pinch Point
Use caution when working in the enclosure to prevent injury.
Heavy Object
Can cause muscle strain or back injury.
Use lifting aids and proper lifting techniques when moving trays, batteries
and otherheavy objects.

4.1 Battery Module Installation
1. Smoking and sparks are prohibited near batteries.
2. Use installation tools with insulated handles. Otherwise, the batteries
may burn out and injury may be caused.
3. Before handling batteries, wear goggles, rubber gloves, and protective
clothes. Remove conductors such as jewelry or watches.
4. Do not use metal to simultaneously touch two or more terminals of the
battery or simultaneously touch a terminal of the battery and a grounded
object (for example, the battery cabinet). Otherwise, short circuits will
occur, which may produce sparks.
5. Battery system must be equipped with firefighting equipment, such as
fire sand, dry powder fire extinguishers.
6. It is strictly prohibited to place installation tools on the battery during
battery installation. After installation, it is strictly prohibited to pile up
sundries on the battery.
1. Transport battery modules to the installation location.
3. Place the battery modules on the rack frame or cabinet.
4. Fix the battery on the rack. Using the cabinet bolt to fix the battery into the hole on the rack.
5. After installation, tighten all bolts.

Figure 4-1: Battery Module Installation (A possible battery install procedure)
1. Please confirm the rack tray load bearing before installation.
2. Please make sure the rack depth meets the requirements before
installation.
3. Support for 19" mounting, there should be rails and pallets, and make
sure the load bearing meets the requirements.
4. In multiple sets of scenarios, installation gap is required. The installation
space of a single battery module should be at least larger than then
battery height. Direct stacking and vertical stacking are not supported.
5. Starting from the bottom up.
5. Cable Connection
5.1 Single Battery Connection

▪Before connect the cable with the inverter, the worker must confirm the
output switch of the inverter has been turn off, to prevent the risk of fire
or electric shock.
▪Before connection, make sure to close the battery.
▪Please follow the instructions to protect the module BMS againstdamage.
▪DO NOT deviate from the sequence of steps below.
▪Exercise extreme caution prevent the terminals from contacting anything
except their intended mounting points.
▪Terminals and their connected wires have either positive or negative
polarity (Positive: +; Negative-). The polarity of a terminal or a wire
connected to the terminal is on the front of each module. Exercise
extreme caution to prevent the terminals and/or wires with opposite
polarity from contacting with each other.
▪In telecom and battery, it is typically designed that positive is grounded.
Therefore, it is necessary to avoid any non-insulating contact between the
negative terminal and the positive terminal of the battery or the rack during
the connection process. This can effectively avoid issues such as
sparking or short circuit.
▪The maximum voltage of the battery is no more than 60V, which is higher
than the safe voltage of 36V. Therefore, we still recommend that the
battery terminals or other exposed parts should not be directly touched
during the installation.
▪When tightening the screws, make sure they are at a straight angle from
the battery module terminals to avoid damage to the nuts inside.
▪Assemble the screws using a Phillips-head within the fasteningtorque of
less than 8.0 Nm (79.88 kgf/cm).

▪The power terminals, such as “+,” “-,” of the module are covered with the
protecting cover to guard against a short circuit (Shown in Figure 5-1).
▪You must remove the insulation cover prior to connecting and reattach
the insulation cover immediately after connecting.
Figure 5-1: Install the Grounding Wire
Step 1 Wear the protective gloves. Step 2 Install the battery ground cable.
Step 3 Install negative and positive power cables for the battery.
1) Remove the protective cover from the battery power wiring terminal.
2) Connect the negative power cable to the battery.
3) Connect the positive power cable to the battery.
4) Install the other end of the battery power cables at a battery route and the corresponding RTN+
busbar in the power system.
5) Reinstall the protective cover on the battery power wiring terminals.

Figure 5-2: Installing Negative and Positive Power Cables
1. Remove the protecting cover.
2. Take-down positive fixing bolt by the Phillips Screwdriver and connect the positive output cable
between the battery positive terminal of the battery and the inverter. After connecting the battery,
fastening bolt immediately to avoid dropping.
Figure 5-3: Single Battery Connection
3. Take-down negative fixing bolt by the Phillips Screwdriver and connect the negative output cable
between the battery negative terminal of the battery and the inverter. After connecting the battery,
fastening bolt immediately to avoid dropping.
4. Install the protecting cover.
5. Sort the cables and fasten the battery cables to the perforated bracket with cable ties.
6. Communication Line Connection

As shown in Figure 5-4, when monitoring the battery by the computer, connect the ‘USB convert to
RS485’communication line between battery and computer.
Figure 5-4: Communication Cable Connections between Battery and Computer
5.2 Connect Cables of the Multiple Batteries in Parallel
When multiple batteries in parallel, the cable connecting procedures are follows.
1. As shown in Figure 5-5, following the cable connection method of the single battery, connect the
positive and negative cables between the Battery 1 and the busbar, Battery 2 and the busbar, and
Battery N and the busbar respectively.
Note: To ensure the current balance, please use cables with the same diameter and length for each
battery.
Figure 5-5: Multiple Batteries Connections

2. As shown in Figure 5-7, connect the communication line (a standard RJ45 network cable) between
the adjacent batteries.
3. When performing multi-machine parallel communication operation, it need to configure the dialing
address of each battery. The dialing code is in BCD format, and the address 0 is defined as
. The dialing address configuration of each battery is shown in Table 5-1.
According to the number of the battery in parallel, set the dialing address of the corresponding
battery.
