1.2 Explanation of Terms

(1) Lithium iron phosphate cell (LiFePO4)
Basic unit constituted by electric poles and electrolytes; Each cell is independent and
closed.
Note: Paralleled cell cannot be regarded as an independent cell, even repacked as one
whole battery pack.
(2) Lithium iron phosphate pack
Combination made up of battery monitoring circuit, battery equalization circuit, electrical
connectors, communication interfaces, thermal management devices and multiple
Lithium iron phosphate cells.
Note: For packs from same company, all the details such as physical size, working
performance and interface specification should be consistent so that all the packs are
compatible and interchangeable.
(3) Battery management system
Electronic equipment collection for monitoring the operating information of cells, packs
and system units (such as voltage, current, temperature, protective parameter of
batteries), evaluating the state of charge (SOC), the state of health (SOH) and cumulative
processed energy and protecting batteries for safety, etc.
(4) Battery system unit
A combination of batteries through series parallel combination inside and a battery
management system (BMS) in which accesses to DC side of a bidirectional converter.
(5) Storage unit
A combination of a bidirectional converter and a battery system unit, which can be used
as an independent load or be controlled directly by monitoring system.

SAFETY INSTRUCTIONS

2.1 Manual Keeping

This manual contains important information about operating the system. Before operat-
ing, please read it very carefully.
The PCS should be operated in strict accordance with the description in the manual, in
case that it causes damage or loss to equipment, personnel and property.
This manual should be kept carefully for maintenance and reparation.

2.2 Operator Requirements

The operators should get a professional qualification, or 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.
While carrying out maintenance work it has to be at least two operators in the field all
the time. They can't operate on any equipment until they are all powered off and fully
discharged.
It is strictly prohibited for any maintenance to be carried out when equipment are on or
charged.

2.3 Protection of Warning Sign

The warning sign contains important information for the system to operate safely and it
is strictly prohibited to torn or damage the sign.
Ensure that the warning sign is always clear.
The signs should be replaced immediately if damaged.

2.4 Setting of Warning Sign for Safety

While instructing, maintaining and repairing, to prevent unrelated personnel nearby to
cause incorrect operation or accident, the suggestions below should be followed:
Obvious signs should be set at front switch 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 which may cause vital electric shock when touched by
accident.
Equipment protection must be taken in 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.
