-12-
Using Terminal Blocks
Three terminal contacts are provided:
Vdc Positive (
+) terminal
Vdc Negative (
-) terminal
Chassis ground
* Working Vdc for general application: +6V ~ +60VDC
* Working Vdc for PoE application : +43V ~ +54VDC (Typ. 48V)
One 3P terminal plugs are provided together with the switch. The plug is shown below:
Power wires : 24 ~ 12AWG (IEC 0.5~2.5mm
2
)
Install the power source wires with the plug properly. Then, plug in the terminal block socket.
Using DC Power Jack
When an external power system is not available, the switch provides a DC jack to receive power from
typical AC-DC power adapter alternatively.
AC Power Adapters: Optional commercial rated adapters are available for purchasing.
Non-PoE applications Rated output DC7.5V 0.5A / 1A / 1.2A
PoE applications Rated input 100V ~ 240VAC, Output 48VDC / 24W (About 20-21W is
reserved for PoE PDs connected.)
Note: * Before you begin the installation, check the AC voltage of your area. The AC power
adapter which is used to supply the DC power for the unit should have the AC voltage
matching the commercial power voltage in your area.
* For PoE applications, make sure the rated output power meets the required voltage
and power consumption required by all connected PD devices. Refer to sec. 3.3 for
more information.
