5 Installation
Installation and commissioning must only be carried out by qualified electrical experts.
The recommended safety regulations, the technical interface conditions (TAB 2000), as well as DIN
VDE 0126-1-1, EN 50438, ENEL G.L. 12/2008 and RD 1663 specifications, should be complied
with.
To carry out an energy measurement, a meter must be attached between the grid feed-in point
and the solar inverter (in accordance with your local utility company directive concerning „In-plant
generation systems on the low-voltage grid“).
By means of the integrated anti-islanding protection, the function of the recommended section
switch is fulfilled in accordance with your local utility company directive.
Caution: The secondary short-circuit current rating is increased at the transfer connection point to
the public electricity supply system by the nominal current of the connected solar inverter.
6 Installation of equipment
6.1 Installation location
• Install the device on a non-flammable support base.
• Avoid installation on resonating bodies (light construction walls etc.).
• Installation is possible both indoors and in protected outdoor areas.
• An increased ambient temperature can reduce the efficiency of the PV system.
• Noise generation is possible (avoid installation in residential areas).
• Ensure legibility of the LEDs and the display (check read-off angle and installation height).
• Although the unit is fitted with UV resistant components, direct exposure to sunlight should be
avoided.
• Despite having an IP65 enclosure and being certified in accordance with soiling category III, the
unit must not be allowed to become heavily soiled.
• Dusty conditions soiling can impair the unit’s performance.
6.2 Minimum requirements
• Free convection around the solar inverter must not be impaired.
• For proper air circulation to dissipate heat, allow a clearance of approx. 10 cm to the side and
approx. 50 cm above and below the unit.
• The grid impedance requirement at the supply terminal is to be observed (cable length, cable
cross-section).
• The recommended installation position is to be adhered to (vertical).
• Unused DC connectors (Tyco) and interfaces must be sealed airtight with sealing plugs to en-
sure protection class IP65 for the whole system (inverter & cables).
