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.
The metal case of the router is not connected to the negative pole of the power sup-
ply (common pole). If recommended for the installation environment, protect the router by
grounding it properly by the grounding screw, see Figure 15.
