Table 2: Power Supply Pinout
Required power supply voltage for the router is between +9 V and +48 V DC, see the
connection scheme on Figure
9. 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 10.
