Commissioning Guide
Before installing and commissioning batteries, prepare fire extinguishing facilities,
such as fire fighting sands and carbon dioxide fire extinguishers, according to
construction standards and regulations. Before putting the battery room into
operation, ensure that it is equipped with a fire extinguishing system that
complies with local laws and regulations, has been constructed and commissioned,
and can work in automatic and manual control modes.
Before unpacking batteries, ensure that the packing cases are intact and correctly
placed according to the labels on the packing cases during their storage and
transportation. Do not place a battery upside down or vertically, lay it on one side,
or tilt it. Stack the batteries according to the stacking requirements on the packing
cases. Ensure that the batteries do not fall or get damaged. Otherwise, they will
need to be scrapped.
After unpacking batteries, place them in the required direction. Do not place a
battery upside down or vertically, lay it on one side, tilt it, or stack it. Ensure that
the batteries do not fall or get damaged. Otherwise, they will need to be scrapped.
Tighten the screws on copper bars or cables to the torque specified in this
document. Periodically confirm whether the screws are tightened, check for rust,
corrosion, or other foreign objects, and clean them up if any. Loose screw
connections will result in excessive voltage drops and batteries may catch fire
when the current is high.
After batteries are discharged, charge them in time to avoid damage due to
overdischarge.
If the electrolyte leaks, absorb and neutralize the electrolyte immediately. Exercise
caution when moving or handling a battery with electrolyte leakage, because the
leaking electrolyte is hazardous.
