SAFETY INSTRUCTIONS

2.4 Setting of Warning Sign for Safety

To prevent erroneous operations and accidents caused by unrelated personnel nearby,
the suggestions below should be followed during the instruction, maintenance and
repairing:
Obvious signs should be set at the front and rear-level switch in case of accidents caused
by false switching.
Warning signs or tapes should be set near the operation areas.
Keys of the system must be pulled out after maintenance or operation.

2.5 Live Line Measurement

High voltage in the container. Touching by accident may cause vital electric shock.
Equipment protection must be taken when do live line measurements (e.g. insulation
gloves).
The measuring equipment should be connected and used correctly to ensure personnel
safety. When measuring, at least two workers are needed.

2.6 Measuring Equipment

Ensure the electrical parameters to match requirements, and related measuring
equipment are required when the system is being connected or tested.
Ensure the connection and operation to match the specification in case of electric arc or
shock.

2.7 Electrostatic Prevention

Contact or improper operation of the printed circuit board or other ESD sensitive
components may result in damage to the device. Unnecessary contact should be avoided.

2.8 Moisture Prevention

It is very likely that moisture may cause damages to the system.
Do not open the container door if the humidity is higher than 95%.
Repairing or maintaining activities in wet conditions should be avoided or limited.

2.9 Operation after Power Failure

The battery system belongs to energy storage system, which maintains fatal high voltage
even when the DC side is disconnected. Therefore, touching of the battery output is
strictly prohibited.
The PCS maintains fatal voltage even when both the DC or AC side are disconnected, so
it must be tested by the multimeter for safety before operation.
