CAUTION: Use the correct conductors!

The conductors must be listed for PV applications and the site environment and

have the correct color coding to avoid material damage and bodily harm.

• To ensure safe and efficient installation, maintenance and repairs the insulation color-

coding of the electrical conductors must be understood. Ensure compliance with the local

and national electrical regulations!

• Lead the conductors away from objects that can damage the insulation (sharp edges etc.).

4.3.2. Connection Area

The DC connections can be configured in three different ways; either by using a stringbox

with DC fuse holders, a stringbox with no DC fuse holders or a connector panel. The

configuration of the AC connections and the network connections are the same regardless

of the different DC connection options.

Prior to the electrical connection the inverter lower cover must be removed (See 2.4.5.

Inverter Structure).
