Required power supply voltage for the router is between +9 V and +48 V DC, see the connection
scheme on Figure 14. Protection against reversed polarity without signaling is built into the router.
For correct operation it is necessary that the power source is able to supply a peak current of 1 A.
Unit has to be supplied by a power supply specified as a Limited Power Source (LPS) or CEC/NEC
Class 2 source of supply.
CAUTION
The metal case of the router is not connected to the negative pole of the power supply (common
pole). If recommended for the installation environment, protect the router by grounding it properly
by the grounding screw on the right panel, see Figure 15.
