Planning the connection of the solar modules (DC)

5.5 Planning the connection of the solar

modules (DC)

5.5.1 Safety instructions

DANGER

Electric shock

Potentially fatal voltages are present at the DC

connections of the inverter. When light falls on

the solar modules, they immediately start to

generate electricity. This also happens when

light does not fall directly on the solar modules.

►

Never disconnect the inverter from the solar

modules when it is under load.

►

Turn both DC isolating switches to the

OFF

position.

►

Disconnect the connection to the grid so that

the inverter cannot feed energy into the grid.

►

Disconnect the inverter from all AC and DC

voltage sources. Make sure that none of the

connections can be restored accidentally.

►

Ensure that the DC cables cannot be

touched accidentally.

NOTICE

Incorrectly dimensioned solar system

If the solar system is dimensioned incorrectly,

this may damage the inverter.

►

When calculating the module string, always

pay attention to technical specifications of

the inverter (

input voltage range

maximum

input current

and

maximum input power

, see

“13. Technical Data”, page 198).

NOTICE

Overheating of the DC connections

Exceeding the

maximum input current

can

cause the DC connections to overheat and

result in a fire.

►

When dimensioning the module strings,

always take into account the

maximum input

current

of the DC connections (see “13.

Technical Data”, page 198).

NOTICE

Ingress of moisture

Moisture can enter via open DC connections.

►

To ensure protection degree IP65, close un-

used DC connections with the rubber plugs

that are attached to the DC connections.

Before connecting the solar modules, turn both DC isolating

switches to the

OFF

position.

5.5.2 Polarity of the DC voltage

►

Check the polarity of the DC voltage of the DC strings be-

fore connecting the solar modules.

The inverter has an integrated function for detecting reverse

polarity on the DC side. If such reverse polarity is detected, the

inverter triggers an error message. This error message is indi-

cated by the

alarm

LED as soon as the inverter is switched on.
