1.2 How To Use This Manual
This manual describes the functions and installation of a PV System-Manager - a solar charge/load
controller in a PV system with a battery as storage.
For safe installation of other components, e.g. solar modules, electrical accessories and battery, please
see the corresponding manual of the manufacturer.
Hint: Before you start your work, read the instructions for Installation (chapter 7; page 18). Make sure that
all preparatory measures are taken.
Only start to install the System-Manager when you are sure that you have understood all the technical
details of this manual. Please make sure that all steps are done in the sequence that is described in this
manual.
These instructions must be handed out to all persons that work with this system. These instructions are
part of the System-Manager and must be handed over in case the System-Manager is sold.
This manual has to be made accessible for any third party or parties working on the PV system.
Before you start work:
•
Read the chapter Installation (chapter 7; page 18)
•
Make sure that all Precautions (chapter 7.1; page 18) are taken.

1.3 General Safety Instructions
For your own safety, please note the following for installation:
Avoid generating sparks!
Solar modules produce current whenever light strikes them. Even at a small light level, the full voltage can
be present. Therefore, work carefully and pay attention to the corresponding safety precautions.
Disconnect the modules with separate circuit breakers while connecting the system.
During installation and wiring of the photovoltaic system, the system voltage may double (with the 12 V
system up to 24 V, with the 24 V system up to 48 V, and within the 48 V system up to 96 V)
Never touch bare wire ends even in DC Systems! This habit can cause injury or even death!
Only use well insulated tools!
Do not use technical tools that are defective or broken!
The safety features of the System-Manager can be defeated when it is operated in a way not specified by
the manufacturer.
Restriction of ventilation can lead to overheating of the System-Manager and thus failure. Do not cover
any ventilating slots or cooling ribs.
The System-Manager must not be installed and used in moist damp areas (e. g. bathrooms) or in rooms
in which there are flammable gas mixtures (from gas bottles, paint, solvents etc.)!
Do not allow anyone to store any of the above-mentioned hazardous items, or similar items in rooms
where the System-Manager is installed!
