Battery Safety Datasheet; General Precautions - Alpha ESS SMILE5 AU Installation, Operation & Maintenance Manual

INTRODUCTION
This sign indicates a hazardous situation which, if not
avoided, could result in death or serious injury!
This sign shows danger of high voltage and electric
shock!
The SMILE5 must not be touched or put into service until
5 minutes after it has been switched off or disconnected
to prevent an electric shock or injury.
This sign shows danger of hot surface!
Refer to the operating instructions.
1.2.4 Setting of Warning Sign for Safety
During instruction, maintenance and repair, follow the instructions below to prevent
non-specialist personnel from causing misuse or accident:
• Obvious signs should be placed at front switch and rear-level switch to prevent
accidents caused by false switching.
• Warning signs or tapes should be set near operating areas.
• The system must be reinstalled after maintenance or operation.
1.2.5 Measuring Equipment
For ensuring the electrical parameters to match requirements, related measuring
equipment are required when the system is being connected or tested.
Ensure that the connection and use matched specification to prevent electric arcs or
shocks.
1.2.6 Moisture Protection
It is very likely that moisture may cause damages to the system.
Repair or maintaining activities in wet weather should be avoided or limited.
1.2.7 Operation After Power Failure
The battery system is part of the energy storage system and stores life-threatening high
voltage even when the DC side is switched off. Touching the battery outlets is strictly
prohibited. The inverter can keep a life-threatening voltage even after disconnecting it
from the DC and / or AC side. Therefore, for safety reasons, it must be tested with a
properly calibrated voltage tester before an installer works on the equipment.

1.3 Battery Safety Datasheet

1.3.1 Hazard Information
Classification of the hazardous chemical
Exempt from classification according to Australian WHS regulations.
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 and 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 strongly by the surrounding
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 dangerous 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.
