PWR(+)
Positive pole of DC supply voltage (+9 to +48 V DC)
2
PWR(-)
Negative pole of DC supply voltage
Table 6: Power Supply Pinout
Required power supply voltage for the router is b9 V and +48 V DC, see the
connection scheme on Figure
. 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
