2.4.3 Installing Battery
Note
1. Large current may occur when operating batteries. Before connecting battery cables, make sure that all battery MCBs are off.
Before the power system is connected to battery string cables, you must switched off all related battery MCBs or the cell
connection straps of the battery string to avoid that the power system is with live power after installation.
2. Check that the polarity of battery and power system connection terminal are consistent on both ends of the battery cable;
otherwise, the battery and power system will be damaged.
3. When replacing or installing batteries in a battery compartment, install batteries from bottom to top, uninstall batteries from
top to bottom, and maintain the center of gravity of the battery compartment.
4. When installing the batteries, check that every screw is tightened on a pole according to the required torque. After a battery
compartment is delivered and used for 1 ~ 2 months, recheck that every screw is tightened on a pole according to the required
torque. Otherwise, fire hazard may occur.
5. Lead-acid batteries may cause chemical hazards.
6. When changing a battery, make sure that the replacement is of the same type and capacity as the replaced battery. Otherwise,
explosions may occur.
7. Scrap used batteries according to related local laws.
8. The system supports maintenance-free valve-regulated lead-acid batteries. When you connect 24 cells of 2V battery or 4 cells
of 12V battery in a series, make sure that the maximum battery capacity is equal to or less than 600Ah.
9. When using one battery string, make sure that the load output current is equal to or less than the MCB capacity of the battery
string. Otherwise, a battery MCB trip may occur.
The maximum dimensions of single battery:
2V 500Ah: 395mm (H) × 185mm (W) × 215mm (D)
2V 300Ah: 395mm (H) × 185mm (W) × 144mm (D)
12V 200Ah: 238mm (H) × 259mm (W) × 497mm (D)
12V 150Ah: 318mm (H) × 125mm (W) × 558mm (D)
Installation procedures of battery are as follows:
1. Switch off the AC input MCB and battery MCB in the power subrack of the power cabinet.
2. Loosen the two fixing screws of the battery baffle plate, and remove the baffle plate.
3. Push the batteries into the battery compartment from right to left. Ensure that every two batteries are 10mm distant
from each other.
4. Remove the protection cover on the battery connection terminal, and connect battery lead plates between batteries
in turn.
5. Connect one end of the negative battery cable to the battery MCB of the power subrack, and then connect the
other end of the negative terminal of the battery string. Connect one end of the positive battery cable to the DC output
busbar, and connect the other end to the positive terminal of the battery string.
6. Attach the temperature sensor of temperature compensation cable onto the surface of the battery case.
