To connect the NetGuardian to a power supply:

.
2. Insert the eyelet of the earth ground cable between the two bolts on the grounding lug (Ground cable
not included).
3. Insert a battery ground into the power connector plug's right terminal and tighten the screw.
4. Insert a battery lead to the plug's left terminal and tighten its screw.
5. Insert fuse into the fuse distribution panel.
6. Check the power status LED for polarity.
7. Measure voltage. Connect the black cable onto the ground connector of your Digital Voltage Meter
(DVM) and red cable onto the other connector of your DVM. The voltmeter should read between -36
VDC and -72 VDC.
Note: If the voltage does not read between -36 VDC and -72 VDC, stop immediately.

connector only one way to ensure the correct polarity.
Note: The negative voltage terminal is on the left and the GND terminal is on the right.
9. Verify that the LED is lit. To confirm that power is correctly connected, the front panel status LED
will flash RED and GREEN, indicating that the firmware is booting up.
