1.2 Safety Introduction

1.2.1 Manual keeping

This manual contains important information about operating the system. Before
operating, please read it very carefully.
The system should be operated in strict accordance with the description in the manual,
otherwise it can cause damages or losses to equipment, personnel and property.
This manual should be kept carefully for maintenance and reparation.

1.2.2 Operator Requirements

The operators should get a professional qualification, or get trained.
The operators should be familiar with the whole storage system, including compositions
and working principles of the system.
The operators should be familiar with the Product Instruction.
During maintenance the maintainer is not allowed to operate any equipment until all the
equipment has been turned off and fully discharged.

1.2.3 Protection of Warning Sign

The warning signs contain important information for the system to operate safely, and it
is strictly prohibited to torn or damage them. Ensure that the warning signs are always
readable and correct placed. The signs must be replaced immediately when damaged.

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 high voltage and electric shock!
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.
To prevent electric arcs or shocks please make sure it is connected and everything is
done according to the specification

1.2.6 Moisture Prevention

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 lethal high voltage
even when the DC side is switched off. Touching the battery outlets is strictly prohibited.
The inverter can keep a lethal 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.
