Grounding System

NOTE

A screwdriver (slotted, 3.5 mm) is to be used for the terminals
in the inverter. Put the screwdriver into the intended cut-out.
Press the screwdriver upwards a bit. Put the cable into the
spring terminal. Put the screwdriver back into the original
position. Remove the screwdriver. The spring terminal is
closed and the cable is held in place. Lightly pull on the
wire to be sure it is secure.

!

CAUTION

Be sure the inverter is confi gured for the proper DC
grounding confi guration of the system.

!

CAUTION

The voltage of the solar generator must be
measured before connecting the DC leads to the
inverter terminals. The DC voltage must not exceed
the max. generator voltage because this would
destroy the unit.

Clamp the enclosed cable bridge in the upper GFDI
terminal and the DC+(Figure 13) or DC-connection
(Figure 14). Consult the module manufacturer for infor-
mation on which generator pole should be earthed.
