Power supply for router is required b10 V to +30 V DC supply. Protection against
reversed polarity without signaling is built into the router.
The power consumption during receiving is 2,3 W. The peak power consumption during
data sending is 5,5 W. However, values of consumption can be increased, if some expansion
port is eqquipped. For correct operation it is necessary that the power source is able to supply
a peak current of 1 A.
Connector on the power cable connects into the power connector on the router head and
tightens locking screws (see figure below).
