1. Safety
The PowerCube-M2 is a high voltage DC system, operated by authorized person only. Read all
safety instructions carefully prior to any work and observe them at all times when working on with
the system.
Incorrect operation or work may cause:
injury or death to the operator or a third party;
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:
training in the installation and commissioning of the electrical system, as well as the dealing
with hazards;
knowledge of the manual and other related documents;
knowledge of the local regulations and directives.
1.1 Symbol
Danger
Lethal voltage!
Battery strings will produce high voltage DC power and can
cause a lethal voltage and an electric shock.
Only qualified person can perform the wiring of the battery
strings.
Warning
Risk of battery system damage or personal injury
DO not pull out the connectors while the system is working!
De-energize from all multiple power sources and verify that
there is no voltage.

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-M2 system working temperature range: 10℃～40℃; 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.
