Utility input and output electrical connections
The inverters are equipped with 4 inputs and 2 outputs to enable a number of solutions for interface with more complex installations.
Figure 10 and Figure 11 show examples of two possible configurations of the inputs and outputs.
For the installer it is sufficient to wire the required input and output contacts and then configure the functions as necessary (see sections
6.6.13 and 6.6.14).
The +19 [Vdc] power supplies to pins 11 and 18 and J5 (18-pole terminal board) can deliver a maximum of 50
[mA].

OUT 1 and OUT 2 output contacts:
The connections of the outputs listed below refer to the two 3-pole terminal boards J3 and J4 marked OUT1 and OUT 2, with a text
below indicating the type of terminal contact.

With reference to the example in Figure 10 and
using the default settings (O1 = 2: contact NO;
O2 = 2; contact NO) the following is obtained:
•
L1 lights up when the pump is blocked
(e.g. "BL": water failure block).
•
L2 lights up when the pump is running
("GO").
