1.1. PERSONAL SAFETY PRECAUTIONS
To prevent personal injury and damage to property please read the following warnings before activating the device for the first time:
Read the operating instructions beforehand!
- Observe the safety warnings!
- Observe the user information!
Risk of electric shocks from live device parts!
In the event of system maintenance, carry out the following steps beforehand:
• Disconnect the photovoltaic system and the AC power supplies.
• Make sure the system cannot be restarted.
• Make sure the electricity supply has been disconnected.
• Earth the equipment sub-assemblies and short-circuit them.
• Cover or separate nearby live device units.
• Before working on circuits upstream make sure the inverter is disconnected by opening the DC disconnection switches.
• If there are field panels upstream of the inverter attach label to them displaying the following information:
WARNING!
DEVICE WITH SEVERAL HAZARDOUS VOLTAGE POWER SUPPLY SOURCES INSIDE EVEN AFTER DISCONNECTION DEVICES
HAVE BEEN OPENED.
ADOPT ALL SAFETY MEASURES REQUIRED FOR PROCEDURES ON LIVE PARTS.
The following measures are required:
- To prevent personal injury and damage to property, the device should only be used by qualified personnel with electrical and
technical training.
- The qualified technician must have read the operating instructions.
- National accident prevention standards must be observed.
- Maintenance and repair procedures must only be carried out by trained personnel authorised by Socomec. The user is strictly
prohibited from carrying out procedures which could involve compromise the integrity of the inverter (for example, removing inverter
modules).
During installation, observe the following:
- Observe the connection conditions and technical data.
- Observe standards regarding electrical installation, e.g. cable cross-section, contactor connection and earthing.
- Do not touch any components and electronic contacts (electrostatic charge could destroy the components).
DANGER!
Risk of electric shock from live device parts!
SUNSYS pro
and
SUNSYS station
inverters can be connected to a maximum of three separately protected power supplies:
1 DC cable - Photovoltaic generator power supply (separate for the three modules or shared)
2 AC cable - Power from the mains network, supplied by the electricity company
3 AC cable - Auxiliary power supply
• Before carrying out any work make sure the electricity supply has been disconnected.
• All DC power supplies should be considered as part of the same circuit, even in the configuration with centralised multi-
string inverter. Before carrying out any work make sure all electricity supplies have been disconnected.
DANGER!
Risk of electric shock from live device parts!
The intermediate inverter circuit may be live even after it has been deactivated.
• Wait 5 minutes for the power to disperse and make sure that there is none remaining.
