5.3 Electrical connection
General
After the inverter has been installed in its fi xed location, the
electrical connection to the unit can be established.
D A N G E R
The Powador may be installed only by trained and
authorised specialists.
All mandatory safety regulations, the currently required techni-
cal connection specifi cations of the responsible power supply
company, as well as other generally applicable regulations are
to be adhered to.
W A R N I N G
Before you connect the inverter, disconnect the AC
and DC sides from all power sources and secure
them against being inadvertently switched back on.
The connection of the PV generator and the grid connection
are established via PCB terminals in the connection box of the
inverter (see fi gure 5.4).
ACTION
The door of the housing must be opened to do this. The
door is held shut with two Phillips recessed-head screws
on the right side of the housing.
NOTICE
At the AC connection terminals, the maximum conductor cross-
section that can be connected is 16 mm² (rigid) or 10 mm²
(fl exible). Length of insulation to be stripped off: 10 mm.
The max. cross-section for leads to be connected to these
DC connection terminals is 6 mm². Length of insulation to be
stripped off: 15 mm.
Tighten the terminal with a torque of 1.2 to 1.5 Nm.
