PV generator connection
The PV generator leads are connected on the left side of the
connection box.
The PV generator can be connected in the following ways:
Cable fi ttings
–
Tyco plug connectors
–
MC plug connectors
–
The cable fi ttings are already installed upon delivery. As an
option, Tyco and MC plug connectors can be delivered with
the inverter.

ACTION
Guide the lead, which has been stripped of its jacket and
insulation, through the cable fi tting.
Connect the lead, which has been stripped of its jacket
and insulation, as is shown on the label on the right side
of the PCB terminal.
CAUTION
Check that the leads are properly connected. Ex-
changing L and N will destroy the inverter.
ACTION
Once again, ensure that all connected leads are fi rmly
connected.
Tighten the cable seal of the cable fi tting.
DANGER
To ensure maximum protection against hazardous
contact voltages while assembling photovoltaic
installations, both the positive and the negative
leads must be strictly isolated electrically from
the earth potential (PE).
ATTENTION
Risk of damage.
Ensure that the polarity is correct when connecting the
unit.
ACTION
Before connecting the PV generator to the Powador,
–
check that the PV generator is not earthed.
Measure the DC voltage between the protective earth
–
(PE) and the positive lead and between the protective
earth (PE) and the negative lead of the PV generator.
If stable voltages can be measured, this indicates an
–
earth fault in the PV generator or its wiring. The ratio
between the measured voltages gives an indication as to
the location of this fault. Rectify this fault before taking
any further measurements.
Measure the electrical resistance between the protec-
–
tive earth (PE) and the positive lead and between the
protective earth (PE) and the negative lead of the PV
generator.
Low resistance (< 2 M
–
Ω) indicates a high-impedance
earth fault of the PV generator, which must be fi xed
prior to continuing with the installation.
CAUTION
The voltage of the solar generator must be meas-
ured before connecting the DC leads to the in-
verter terminals. The DC voltage must not exceed
500 V
DC
. Connecting to a higher voltage will de-
stroy the unit.
