Vdc Power Cable Connection - Toshiba V Series Operation Manual

4.4 12 VDC Power Cable Connection

• Be sure to use a heat-resistant, insulated cable of AWG22 (0.75 mm2) or over as power
cable.
• Be sure to keep the cover on the terminal board to prevent electric shock.
• Do not apply 100 VAC to the terminal board by mistake. Otherwise, it may cause smoke or a
fire.
• Use a separate +12 VDC power supply for each Ethernet module. If this is not possible, wire
the Ethernet modules in such a way that each module can be separately switched off.
• Use a +12 VDC power supply with a protective circuit.
The EN711 or EN721 receives the +12 VDC power for AUI transceivers at the terminal
board TB from outside the EN7 module.
Connect the power cable to the terminal board TB with a M3 screw.
Applicable models: EN711, EN721
