Quick installation guide for RPI H3 inverters EU EN 5013227802 02 2016-01-05

Connecting digital inputs and dry contacts (optional) 

10

When your grid operator wants you to set a 
power limitation, e.g. for the 70% regulation in 
Germany, you need the Delta Service Software, 
which is available from Delta.

If you need to wire dry contacts, digital inputs or 
RS485, it is recommended to do this in a dry en-
vironment and before you hang the inverter onto 
the wall.  Reasons for this are:

 

You will have to remove the covers from the 
connection ports. Water could leak into the 
inverter.

 

The terminal blocks inside are not easily 
accessible.

Dry contacts

When the inverter is feeding into the grid, the dry contact is 
closed.

Connecting a PC via RS485

If you want to use a PC with the Delta Service Software to set up 
the inverter, you need a USB/RS485 adapter to connect the PC 
to the RS485 terminal block of the inverter. 

The USB/RS485 adapter is available from Delta.
