2.7 Power Supply
A two-pin terminal connector (pitch 3.5 mm) is utilized to power the router. The corresponding connector
is included as a standard accessory with the router.

The required power supply voltage for the router ranges between +9 V and +48 V DC. Refer to the
connection scheme in Figure
reversed polarity, functioning without signaling. To guarantee correct operation, the power source must be
capable of providing a sufficient amount of energy, as detailed in the consumption section of Chapter 4.1.
Grounding the router using the grounding screw eliminates the protection against reversed polarity.
Ensure the negative pole of the DC power supply shares the same voltage reference as the grounding
screw. A voltage difference between these points may damage the router, necessitating repairs
exclusively by an authorized service center.
The power voltage for the PoE router version must be 48 V DC for it to function as a PoE PSE device.
All metal parts, including the box, are interconnected with the negative pole of the power supply (common
pole). If recommended for the installation environment, protect the router by properly grounding it using the
grounding screw, as depicted in Figure 18. The maximum tightening torque for the grounding screw is
1 Nm.
