Power supply for router is required b9 V to +36 V DC supply. Protection against
reversed polarity without signaling is built into the router.
Note:
The protection against re-
versed polarity is lost if the negative pole is grounded! The only protection left is the fuse
inside of the device.
For correct operation it is necessary that the power source is able to supply a peak current
of 1.2 A.
