Fusing
PoE power supply requires no fuses. The power supply fusing depends on the cable
cross-section and length.
Attention!
Recommendation for fusing relates to 40W@24VDC at 100 meters and
1.5 mm

Attention!
When the heating switches on, high current peaks occur! Use slow-
blow fuses.
Attention!
Please pay attention to the national and international regulations re-
garding selectivity and line protection.

Plug assignments (RJ45)
The data transfer of the ExCam XF Q1645 series uses a 100 Mbit/s Ethernet connection
(100BASE-TX). If the cable termination uses a plug, the latter should be plugged into the
RJ45 PoE slot of the network device (PSE). Prior to connecting it to the camera, the net-
work device (PSE) can already be supplied with power, hence there is no „power ON“
priority which has to be observed.
Attention!
Use appropriate RJ45 plugs! Check the cable shielding, cross-section
and the outside diameter!
Attention!
It is imperative to ensure a correct routing of the individual wires ac-
cording to the EIA/TIA-568B"
Attention!
Finally, check your network installation with a Class-D Link Test.
