2.2.4 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 9 and Figure 10 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].
2.2.4.1 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.
Output contact specifications
Type of contact NO, NC, COM
Max. admissible voltage [V] 250
Max. admissible current [A]
5 -> resistive load
2,5 -> inductive load
Max. admissible cable section [mm²] 3,80

2.2.4.2 Input contacts (photocoupled)
The connections of the inputs listed below refer to the 18-pole terminal board J5, with numbering starting from pin 1 from the left. The
base of the terminal board also bears the text of the corresponding inputs.
- I 1: Pins 16 and 17
With reference to the example in Figure 9 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").
