Installation of Battery Modules

1.Installation and xation

Battery modules of NPFC series are applicable to installation in cabinets and wall-hanging.

■ cabinet installation

Insert battery module into cabinet, and x two handles of battery module with cabinet rack using

4pcs M6 screws.

■ Wall-hanging installation

Wall-hanging installation also can be adopted, x two handles of battery module with triangle rack

on the wall using 4pcs M6 screws.

2.Ground connection

Connect earth by exible cable above GREEN Sheathed, UL94-V0, gauge of the grounding wire

should be equal to or greater than the gauge of the battery return wire, .no less than 6AWG,

Alternate

3.Battery output connection

■ Connect ‘+’ of battery output with positive copper bar of power plant, and ‘-’ with negative copper

bar or power switch.

■ If multi battery modules will be connected in parallel, please take note of follows:

The battery modules connected no more than 8 in parallel.

The minimum spacing between batteries is 10mm.

Connect ‘+’ of battery output of each battery module with positive copper bar of power plant,

and ‘-’ with negative copper bar of power plant or power switch separately.

Length of cable between battery module and power plant shall be less than 2.0m. To make sure

similar voltage drop of cable for each battery, length of all positive and negative cables should be

the same.

■ Color for cable between ‘+’ and positive bar is suggested as RED, and cable between ‘-’ and

negative as BLACK.

■ The picture of paralleling connection for NPFC Series Batteries see Fig. 4-2. There is a tray under

each battery to support the battery.

Fig. 4-2 Layout of paralleling connection for NPFC Series Batteries

4.Power on for battery module

■ When installation is accomplished, battery module is in dormant state. Once power on for the

power plant and battery module, battery will go into normal running status, and discharge/charge

can be available.

■ Parameter settings for lithium battery modules in power plant are shown in Table 3-1.

6.Discharge with dummy load

■ Dummy load cannot be larger maximum discharge current of each battery model according to the

datasheet, and BLVD is larger than 43.2V.

■ Voltage drop on cable between battery module and power plant shall be less than 0.5V. Method of

calculation for cross sectional area of cable is shown as below.

A=ΣI×L/(K×△U)

In the above formula, A is across sectional area of wire (mm2), ΣI is the total current (A), L is length

of cable, △U is the permit voltage drop on cable (V), and K is electrical conductivity of wire. For

example, for copper, K = 57.

5.RS232/RS485 communication connection

■ If there is only one battery module in operation, communication between battery module and

computer can available through RS485.

■ If there are more than one battery modules in operation, parallel communication can be available

using RS485.

■ The last battery in each rack have an empty RS485 port for CAN cable terminal resistor. The other

end of communication cable, use the electric tape to seal it.

■ RS232 communication port just for software upgrade.

■ Communication protocols for RS485 are shown in Annex 3.

■ Dry contact should be connected when battery connected in electric circuit.

General

Proper maintenance will prolong the life of a battery and will aid in assuring that it can satisfy its

design requirements. A good battery maintenance program will serve as a valuable aid in determining

the need for battery replacement. The users must consider their application and reliability needs

if maintenance procedures, other than those recommended in this document, are used. Battery

maintenance should be performed by personnel knowledgeable of batteries and the safety

precautions involved.

■ The battery shall be recharged every three months if in long time storage

■ Please clean the dust by the dust collector when dust is accumulated on vent

■ Please use clean and dry cloth/fabric to clean up the cabinet, if need further cleaning, please use

neutral cleanser. Alcohol or ammonia synthesis is forbidden.

■ Carrying shall be handled gently, prevent from severe compact

■ Prevent battery from splashing liquid

■ Suggest inspect the tighten of output screw every two years
