APPLYING POWER (702-W Side View)
Unscrew & Remove the DC Voltage Input Plug from the Power Input Header
Install the DC Power Cables into the Plug (observing polarity).
Plug the Voltage Input Plug back into the Power Input Header.
Tightening torque for the terminal block power plug is 0.5 Nm/0.368 Pound Foot.
Verify the Power LED stays ON (GREEN).
Notes:
Only 1 power supply must be connected to power for minimal operation. For redundant power
operation, V
1
and V
2
inputs must be connected to separate DC Voltage sources. This device will
draw current from both sources simultaneously. Use 16-28 gauge wire when connecting to the
power supply.
The LAN port supports Power over Ethernet and can be used redundantly with the power input
mentioned above.
