1Overview
1.1 Scope of this document
This instruction manual is an important part of the battery system Power Battery 3.8 / 5.7 / 7.6 / 9.6 / 11.5. It contains
information about working safely and efficiently with the battery system.
Always keep the operating instructions near the battery system.
Persons who carry out maintenance or service work on the battery system must always have access to the instructions and
information in this operating manual.
Read the operating instructions before installing the system. Pay particular attention to the safety instructions.
This operating manual contains information on the installation, wiring, commissioning and operation of the battery system.
This document does not replace any laws, regulations, rules, standards or conventions.
1.2 Intended use
The battery systems Power Battery 3.8 / 5.7 / 7.6 / 9.6 / 11.5 are stationary battery systems with lithium-iron-phosphate
accumulators (LiFeP04).
A Power Battery in combination with a Power Storage forms a Power Storage System that stores the generated PV energy
intelligently and highly efficiently and makes it available to the consumer again according to economic aspects.
The Power Battery has not been developed for other applications or connections to other devices.
Any use that differs from the intended use is considered misuse. RCT Power GmbH is not liable for any damage resulting
from misuse.
Any misuse will terminate the manufacturer's warranty, guarantee and general liability.

1.3 Explanation of symbols
The following symbols may appear on the type plate and/or on the unit. These symbols must always be observed:
Observe the operating instructions!
Acid traces in the eyes or on the skin clean with lot of clear water.
Then consult a doctor immediately!
Wash contaminated clothing with plenty of water.
Fire- extinguisher for abatement from initial fire.
Warning!
Metal parts of the batteries are always under voltage.
Do not short-circuit the batteries!
In case of a short-circuit, may flow very high currents and cause burns.
By Touching conductive parts can cause cardiac arrhythmia and shock.
Explosion risk!
It is strictly forbidden to clean with synthetic cloths or a feather duster. Otherwise there is the risk of
electrostatic charging or discharging.
Electrolyte is highly corrosive!
In normal operation, contact with the electrolyte is not possible.
In the case of destruction of the housing, the liberated bound electrolyte is just as corrosive as liquid
electrolyte.
Warning of battery hazards.
Battery must not get wet.
Defective battery must not be operated.
Caution!
Children should be keep away from the battery system.
This product must not be disposed of as normal household waste, → Chapter 7 "Storage, cleaning
and disposal", page 21
