It is imperative that you observe the safety instructions with regard to the electrical voltage! It is particularly important to ensure that a power supply unit with functional extra-low voltage (PELV) is used.
Alternative 1 via Connector X10 (Terminal Block):
Before connection, provide the cable cores with ferrules with collars. The maximum conductor cross-section is 1.5mm² / AWG16.
A shielded cable is required to ensure trouble-free operation even under extremely unfavourable ambient conditions with complex cabling conditions. Connect the cable shield on the Irinos box side to the FE bolt on the base plate. This is marked accordingly inside the base box.
Alternative 2 via Connector X11 (Power Supply Connector):
The connection is made via a 2.5mm jack plug, which is de facto standard for PELV-based desktop power supplies. GND is external, 24V is internal.
