Safety Equipment Required For Grid Connected Systems - Eltek Valere Theia He-t User Manual

3.2.2. Installation
The installation of the inverter must be performed in accordance with the relevant local and
national electrical regulations!
DANGER: Ensure a safe installation of the inverter!
Only persons who are qualified to install high voltage electrical equipment and are
familiar with the electrical regulations applicable to the installation site may install
the inverter. This to ensure a safe installation and avoid possible injury!
WARNING: Ensure a suitable installation site!
Protect the inverter from flammable and explosive environments to avoid fire, as the
inverter heat sink can reach temperatures of up to 90° C / 194° F during long-
periods of high performance operation.
• Ensure a clean, non-dusty, dry and cool environment for optimum inverter performance, and
a non-flammable and non-explosive environment to avoid possible fire.
• Ambient air temperature during operation should be between -25 °C and +65 °C / -13 °F
and 149 °F. If the temperature rises above +45 °C / 113 °F the inverter will automatically
reduce power to protect internal components.
• Non-condensing relative humidity must be between 4 % and 99 %.
CAUTION: Avoid installations with direct exposure to sunlight!
Direct sunlight may cause yield losses, as it can result in increased internal
temperatures that can lead to reduced power output.
• Ensure a location where people cannot accidentally come in contact with the inverter
surface, due to danger of skin burns.
• The inverter is suitable for outdoor operation, but should be sheltered from direct sunlight,
snow, rain, dust and sand.
• Location should be in proximity to the PV arrays to minimize DC losses.

3.3. Safety Equipment Required for Grid Connected Systems
