Installation manual M250HV_112 (RPI254M112000) Product Version 0 EU V1.0 EN 2022-04-11

Safety instructions

Read this manual in full before starting work 
on the inverter.

DANGER 

Electric shock

Potentially fatal voltages are present in the 
inverter during operation. When the invert-
er is disconnected from all power sources, 
this voltage remains present in the inverter 
for up to 150 seconds. 
You should therefore always carry out 
the following steps before working on the 
inverter:

 

Never disconnect the inverter from the 
solar modules when it is under load. 

1.  Disconnect the connection to the grid 

so that the inverter cannot feed energy 
into the grid. 

2.  Turn all four DC isolating switches to 

the 

OFF

 position.

3.  Disconnect the inverter from all AC and 

DC voltage sources. Make sure that 
none of the connections can be re-
stored accidentally.

4.  Wait at least 150 seconds until the 

internal capacitors have discharged.

5.  Ensure that the DC cables cannot be 

touched accidentally.

DANGER

Electric shock

The inverter has a high leakage current 
value.

 

Always

 connect the ground cable first, 

then the AC and DC cables.

DANGER

Electric shock

In IT grids, a twofold insulation fault can 
lead to high residual currents on the invert-
er housing.

 

Ground the housing of the inverter via 
the grounding connection.

 

Set up a permanent insulation 
monitoring system.

 

► The first time an insulation fault occurs, 

this insulation fault must be rectified 

immediately

!

DANGER

Electric shock

Potentially fatal voltages are present at the 
DC connections of the inverter. When light 
falls on the solar modules, they immedi-
ately 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. 

1.  Disconnect the connection to the grid 

so that the inverter cannot feed energy 
into the grid. 

2.  Turn all four DC isolating switches to 

the 

OFF

 position.

3.  Disconnect the inverter from all AC and 

DC voltage sources. Make sure that 
none of the connections can be re-
stored accidentally.

4.  Wait at least 150 seconds until the 

internal capacitors have discharged.

5.  Ensure that the DC cables cannot be 

touched accidentally.

WARNING

Electric shock

IP66 protection degree is no longer guar-
anteed when the door is open.

 

Only open the doors when absolutely 
necessary.

 

Do not open the doors if water or dirt 
might enter the inverter. 

 

After work is completed, ensure that the 
door is properly shut and the screws 
tightened again. Check that the door is 
properly sealed.

WARNING

Heavy weight

The inverter is very heavy.

 

Lift and transport the inverter with suit-
able lifting equipment, such as a crane.

 

At least three people are required to lift 
and carry the inverter.
