1. Safety
The PowerCube-X1/X2 is a high voltage DC system, operated by authorized person only. Read all
safety instructions carefully prior Xto any work and observe them at all times when working on with
the system.
Incorrect operation or work may cause:
Ø Injury or death to the operator or a third party;
Ø Damage to the system hardware and other properties belonging to the operator or a third
party.
Skills of Qualified Person
Qualified personnel must have the following skills:
l Training in the installation and commissioning of the electrical system, as well as the dealing
with hazards;
l Knowledge of the manual and other related documents;
l knowledge of the local regulations and directives.
1.1 Symbol
Danger
Lethal voltage!
l Battery strings will produce high voltage DC power and can
cause a lethal voltage and an electric shock.
l Only qualified person can perform the wiring of the battery
strings.
Warning
Risk of battery system damage or personal injury
l DO not pull out the connectors while the system is working!
l De-energize from all multiple power sources and verify that
there is no voltage.
Caution
Risk of battery system failure or life cycle reduces.

Danger: Batteries deliver electric power, resulting in burns or a fire hazard when they are short
circuited, or wrongly installed.
Danger: Lethal voltages are present in the battery terminals and cables. Severe injuries or death
may occur if the cables and terminals are touched.
Warning: Do not open or deform the battery module;
Warning: Whenever working on the battery, wear suitable personal protective equipment (PPE)
such as rubber gloves, rubber boots and goggles.
Warning: PowerCube-X1/X2 system working temperature range: 0 ℃ ～ 50 ℃; Optimum
temperature: 18℃～28℃.Out of the working temperature range may cause the battery
system over / low temperature alarm or protection which further lead to the cycle life
reduction as well as. It will affect the warranty terms as well.
Caution: Improper settings or maintenance can permanently damage the battery.
Caution: Incorrect inverter parameters will lead to the premature aging of battery.
2. System Introduction

3.3 System Working Environments Checking
3.3.1 Cleaning
The battery system has high voltage connectors. The clean condition will cause the isolation
characteristic of the system.
Before installation and system working must clean the dust and iron scurf to keep the environments
cleaning. And the environment must have certain anti-dust ability.
The system after long term running must check the humidity and dust cover or not. If heavy dust
cover with high humidity on the system should stop the system running and make clean specially
for the high voltage connectors.
Danger: the power cables and plugs still have high voltage DC power from serial connected
battery modules (battery module can’t be turned off), must be careful to handle the
Power Plugs.
3.3.2 Temperature
PowerCube-X1/X2 system working temperature range: 0℃～50℃; Optimum temperature: 18℃～
28℃.
Caution: Out of the working temperature range may cause the battery reduces the cycle of life
even cause the battery system over / low temperature alarm or protection.
3.3.3 Cooling System
The room must be equipped with cooling system.
Caution: Out of the working temperature range may cause the battery reduces the cycle of life
even cause the battery system over / low temperature alarm or protection.
3.3.4 Heating System
The room must be equipped with heating system. If the environment is lower than 0℃, must turn
on the heating system at first.
Caution: Out of the working temperature range may cause the battery reduces the cycle of life
even cause the battery system over / low temperature alarm or protection.
3.3.5 Fire-extinguisher System
The room must be equipped with fire-extinguisher system for lithium-ion battery.
The fire system needs to be regularly checked to be in normal condition. Refer to the using and
maintenance requirements of local fire equipment relevant.
3.3.6 Grounding System
Before the battery installation must sure the grounding point of the basement is stable and reliable.
If the battery system is installed in an independent equipment cabin (e.g. container), must make
sure the grounding of the cabin is stable and reliable.
The resistance of the grounding system must ≤100mΩ
