2. IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS– This manual contains important instructions for SUNSYS HES L systems (see “Concerned
products”) that shall be followed during installation and maintenance of the storage inverter.
A potential Shock and Injury Hazard exists when working on or around electrical systems which could lead to serious
injury or even death. Only qualied competent personnel who have been trained in and are familiar with the Risk of Electric
Shock and Plasma Arc Flash Hazards may perform installation and maintenance on electrical systems. It is the sole
responsibility of the personnel doing the work to be fully cognizant of all necessary safety regulations and procedures and
be familiar with the installation instructions detailed in this manual.
CAUTION!
Any work carried out on the equipment must be performed by skilled, qualied technicians.
The input and output circuits are isolated from the enclosure; the system grounding, when required by
Sections 690.41, 690.42, and 690.43 of the National Electric Code, ANSI/NFPA 70, is the responsibility of the
installer
The wiring methods in accordance with the National Electrical Code, ANSI/NFPA 70 and Canadian Electric
Code (CEC) are to be used. All national standards applicable to batteries must be observed.
CAUTION!
Each power supply line must be provided with overcurrent protection according to the indication contained in
the present manual.
This inverter complies with Part 15 of the FCC Rules Operation so it may not cause harmful interference and
must accept any interference received, including interference that may cause undesired operation.
Overcurrent protection for the AC circuit is to be provided by the installer.
Before carrying out any operations read the SUNSYS HES L system instruction manual and Battery Energy
System (BES) safety instructions carefully, in order to work under safe conditions.
If the Battery Energy System (BES) is not supplied by SOCOMEC, overcurrent protection for the BES is to be
provided by the installer.
CAUTION!
Any work carried out on the equipment must be performed by skilled, qualied technicians.
CAUTION!
Before carrying out any operations on the unit read the installation and operating manual carefully. Keep this
manual safe for future reference.
DANGER!
Failure to observe safety standards could result in fatal accidents or serious injury, and damage equipment or
the environment.
CAUTION!
If the unit is found to be damaged externally or internally, or any of the accessories are damaged or missing,
contact SOCOMEC. Do not operate the unit if it has suffered a violent mechanical shock of any kind.
CAUTION!
Install the unit in accordance with the minimum distances from near walls in order to guarantee sufcient
ventilation and access to handling devices (see Environmental requirements chapter).
CAUTION!
Only use accessories recommended or sold by the manufacturer.
CAUTION!
When the equipment is transferred from a cold to a warm place wait before operating the unit to avoid
condensation.
