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 negative pole of the router is grounded, there is no protection against reversed
polarity! The only protection left is the fuse inside the device. Only the service center can
restore the router’s functionality.
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.
In applications requiring low power consumption (such as solar power - not 7/24 mode)
is strictly recommended to use "LPM" mode prior to powering down the entire router.
Circuit example:
Figure 13: 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.
