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., RD 1663, RD661, UTE 15712-1, Synergrid C10/11 and
G83/1-1 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.

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).
