Required power supply voltage for the router is between +9 V and +48 V DC, see the connection scheme
on Figure 12. 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.
All metal parts of the router in a metal box, including the box itself, are connected with 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, see Figure 13.
