Safety
CAUTION
:
Li-Ion battery (energy storage unit) inside. When assembling the system, do not intentionally make a short condition between the positive (+) and negative (-)
terminals of the battery box with a metallic object.
All work on the B-Box and electrical connections must be carried out by qualified personnel only. B-Box provides a safe source of electrical energy when
operated as intended and as designed.
Potentially hazardous circumstances such as excessive heat or electrolyte mist may occur under improper operating conditions, damage, misuse and/or abuse.
Personnel working with B-Box must review applicable federal, state and local regulations as well as the industry standards regarding this product.
Installation personnel cannot wear watches, etc., to avoid short circuit and human damage.
When Increase battery, should power off the battery and other power input first.
Ensure reliable grounding. Do not reverse the front panel.
Can't use the deformation of the battery.
By checking to verify the installation Settings are correct.
Need to clean, smooth, waterproof, and so on and so forth, the installation.
