This user manual specifies installation and maintenance procedures, technical data and safety instructions for SOCOMEC solar
inverters. For further information visit the Socomec website: www.socomec.com.
Any work carried out on the equipment must be performed by skilled, qualified technicians.
1.1. SAFETY SYMBOLS AND INSTRUCTIONS
WARNING!
Failure to observe safety standards could result in fatal accidents or serious injury, and damage
equipment or the environment.
WARNING!
Device with several power supply sources.
In the event of system maintenance, carry out the following steps beforehand:
- Open the AC switch.
- Open the DC switch.
- Make sure the system cannot be restarted.
- Make sure the electricity supply has been disconnected.
WARNING! RISK OF ELECTRIC SHOCK!
The equipment includes capacitors that store energy. After disconnecting all power sources wait for
the capacitors to discharge.
WARNING! RISK OF BURNS!
During operation the temperature of the casing may exceed 70 °C. Do not touch the surfaces!
Keep this manual safe for future reference.
Before carrying out any operations on the inverter read the Installation and Operating Manual carefully.
Do not dispose of the inverter with normal household waste.
At the end of its working life, the inverter must be disposed of in accordance with local regulations for
the disposal of electronic components applicable to the installation site at the moment of disposal.
The following precautions must be taken in order to avoid risks of overheating, fire. electric shock, mechanical shock, and collateral
damage (persons and/or property):
• Do not cover or obstruct the inverter.
• Do not install the inverter inside a cabinet in an enclosed, non-ventilated area.
• When installing the inverter comply with the recommended clearances (see chapter 4.2).
• Only use accessories recommended or sold by the manufacturer.
• Ensure the wiring is in good condition and not undersized.
• Do not operate the inverter with damaged or substandard wiring.
• Do not operate the inverter if it has suffered a violent mechanical shock of any kind (fall, impact, etc.)
• Before cleaning or performing maintenance work on the inverter or connected appliances, disconnect the power sources. After
disconnecting wait for the internal capacitors to discharge completely (5 minutes approx).
• Inverter earth connection. See Chapter 5.
