General Precautions - Alpha ESS Storion-SMILE5 Installation, Operation & Maintenance Manual

Your Smart Energy
Classification of the hazardous chemical
No danger in normal use. The materials within the battery may only represent a hazard if the structural
integrity of the battery is compromised. Do not expose the batteries to fire or open flame. Do not mix
batteries of varying sizes, chemistries, or types. Do not short circuit, puncture, incinerate, crush, over-
charge, over discharge, or expose the batteries to temperatures above or below the declared limit.
Damage to the batteries will result in the risk of fire or explosion, which could release dangerous
hydrogen fluoride gas and exposure to the ingredients contained within or their combustion products
could be harmful.
Other hazards
This product is a Lithium Iron Phosphate Battery with certified compliance under the UN
Recommendations on Transport of Dangerous Goods, Manual of Tests and Criteria, Part III, sub-section
38.3. For the battery cell, chemical materials are stored in a hermetically sealed metal case, designed
to withstand temperatures and pressures encountered during normal use. As a result, during normal
use, there is no physical danger of ignition or explosion nor chemical danger of hazardous materials'
leakage. However, if exposed to a fire, added mechanical shocks, decomposed, added electric stress
by misuse, the gas release vent will be operated. The battery cell case will be breached at the extreme.
Hazardous materials may be released. Moreover, if heated by close fire, acrid or harmful fume may be
emitted.

1.4 General Precautions

DANGER
Danger to life due to high voltages of the PV array, battery and electric shock.
When exposed to sunlight, the PV array generates extremely high DC voltage which will be present
in the DC conductors and the live components of the inverter. Touching the DC conductors or the live
components can lead to lethal electric shocks. If you disconnect the DC connectors from the system
under load, an electric arc may occur, leading to electric shock and burns.

Do not touch uninsulated cable ends.

Do not touch the DC conductors.

Do not open the inverter and battery.

Do not wipe the system with damp cloth.

Have the system installed and commissioned by qualified people with the appropriate skills
only.

Prior to performing any work on the inverter or the battery pack, disconnect the inverter from
all voltage sources as described in this document.
WARNING
Risk of chemical burns from electrolyte or toxic gases.
During standard operation, no electrolyte shall leak from the battery pack and no toxic gases shall
form. Despite careful construction, if the Battery Pack is damaged or a fault occurs, it is possible that
