15. Connecting the digital input
The digital input is designed to operate with one dry contact or a DC voltage from 0 to 24 V. It can be configured
for different uses using the display.
This chapter explains the requirements and process for connecting the digital input wiring to the unit. Read
carefully before starting the connection process.
15.1. Safety instructions for connecting the digital input
Before you start to make the connections, make sure there is no voltage in the inverter. Check that
the AC protection of the auxiliary grid/genset and the DC switch are open.
Do not switch on the power to the unit until you have successfully made the rest of the connections
and the unit is closed.
15.2. Wiring requirements for connecting the digital input
The wiring gauge for connecting the digital input is specified in the following table:

Temperature sensor wiring gauge 0.25 mm 2 ~ 1.5 mm 2
Cable diameter 4.5 ~ 10 mm
15.3. Connection process of the digital input
To connect the digital input:
1. Loosen the corresponding packing gland (see Section “2.7. Description of wiring inlets” ), remove the cap
and pass the cable through it.
2. Connect the wiring to terminal J54 DIGITAL INPUT as shown in the previous figure, respecting the printed
polarities on the screen-printed electronic card (+, GND). Ingeteam recommends using a tubular terminal in
accordance with
DIN 46 228/1 .
3. Correctly tighten the packing glands to prevent losses to the protection class, verifying that the wiring is
not taut. Check that the connection is tight.
