It is strongly advised that the power supply has its own short circuit protection with
a short circuit output current ranging from 4.3 to 5.0 A.
–
When the power supply has an automatic restart after a short circuit, this restart
function should have an interval time of 3 to 4 seconds and should have no more
than 4 restart attempts.
–
Upon powering off the power supply, the output should be less than 9 V, 1 mA.
–
The maximum distance between the (A)PS and the conference device is limited to 100 m
due to the Ethernet properties.
