Power supply for router is required b9 V to +36 V DC supply. Protection against
reversed polarity without signaling is built into the router.
If the router is grounded, using the grounding screw, there is no protection against the
reversed polarity. The negative pole of the DC power supply must be at the same voltage
reference as the grounding screw. If not, a voltage difference between these two points
might damage the router, and only an authorized service center can fix it.
For correct operation it is necessary that the power source is able to supply a peak current
of 1.2 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.
Circuit example:
Figure 11: Connection of power supply
All metal parts, including the box, are connected together with the negative pole of power
supply (common pole). To ground the router can be used the grounding screw located on the
left panel.
