System Operation

4.1 Start System
After installation, the system is in a dormant & inactive state, when connect charging power source or loaded to the positive and negative electrodes, the system will be opened to a normal working state automatically
4.2 Close system
Disconnect power source and load, after a certain period, the battery system will get into a dormant inactive state initiatively.
4.3 Charge
When charging, the charging module parameters should be set in accordance with the following table.
Table 4-1 Charge parameter setting

Note
The charging voltage should be adjusted and set by an engineer from the manufacturer, once adjusting is complete, it usually does not need to more adjust, unless replacing the charging module.
4.4 Discharge
To ensure that the load current does not exceed the max continuous operation current when connect to the load, disconnect the voltage set to >40.5V
Note:
Increasing load under DC electrification requires a strict tool and human insulation measurement, prevent from an accident or short circuit in operation.
The specification of cable (cross-sectional area) can be selected according to the following formula, which is determined by permit voltage drop, A=EIxL/ ( Kx AU )
In formula:
A is across a sectional area of wire ( mm2); EI is the total current through the wire ( A ) ;
L is the return circuit length of wire ( m ); AU is the permit voltage drop on wire ( V ) ;
K is the electrical conductivity of wire, For example, for copper, K = 570
Recommend using color code to distinguish the polarity of wire: positive is black, negative is blue
