2.2 WiringPowerInputs
The Power input port is located at the bottom side, and provides 2 power input
connections in one 4‐pin removable terminal block. The power port support polarity
reverse protection; the Switch won’t start if wrong polarity applied. The wiring

2. Tightenthewire‐clampscrewstopreventthepowerwiresfrombeingloosened.
3. Connect the power wires to suitable AC/DC Switching type power supply. The
PMI‐110‐F2G provides Power over Ethernet function and is compliant with
IEEE802.3af/IEEE802.3atstandards;therefore,theinputDCvoltageshouldbein
therangeofDC46VtoDC57V.

For the safety issue, turn off AC power input source before connecting the AC/DC
Power supply module and the terminal block connectors. Besides, don’t turn‐on the
source of AC/DC power module and make sure all connections were well done then
power on the AC source to powering the Switch device. Otherwise, your screwdriver
blade may inadvertently short your terminal connections to the grounded enclosure
andcausedamage.
