5�2�3 Connecting the inverter to the PV generator
DANGER!
Fatal electric shock hazard!
In daylight the PV generator supplies the inverter with a dangerously high DC
voltage.
■
The PV generator voltages are very high. NEVER plug or unplug the DC con-
nectors when the inverter is turned on, otherwise dangerous electric arcs
could develop.
10 min
DANGER!
Fatal electric shock hazard!
Components within the inverter are charged with a high voltage.
■
Before attempting any action on the DC connections, make sure
that the DC switch is switched off
■
Wait 10 minutes to rule out any residual risks
■
Do not connect either PV generator pole to ground. Make sure that
positive and negative poles are free floating to earth potential.
This inverter is equipped with a MPPT circuit having the following characteristics:

CAUTION!
Never exceed the absolute maximum ratings indicated in the above table under
any environmental operating condition.
One or more pairs of cables arrive from the PV system for connection to the inverter. The
following figure shows the DC connection range of the 20SHT and the 30SHT:
