APPLYING POWER (Side View)
• Unscrew & Remove the DC Voltage Input
Plug from the Power Input Header
• Install the DC Power Cables into the Plug
(observing polarity).
• For best results keep the power cable length
to a maximum of one (1) meter.
• 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).
Note: 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.
