connectors.
NetGuardian AAR Power Terminals and Fuses
To connect the NetGuardian AAR to a power supply:
1. Locate the metal grounding lug next to the symbol
. Use the grounding lug to connect the unit to earth ground.
2. Insert the eyelet of the earth ground cable between the two nuts on the grounding lug (Ground cable not included).
3. Choose a barrier plug power connector to attach your power cable to. One plug is used for main power and the
other is used for backup power. Both plugs are interchangeable so it does not matter which plug you select. Each
plug's right terminal is Ground and its left terminal is Battery Lead.
4. Insert a battery ground into the power connector plug's right terminal (GND) and tighten the screw.
5. Insert a battery lead to the plug's left terminal and tighten its screw.
6. Insert fuse into the fuse distribution panel.
7. Check the power status LED for polarity.
8. 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 the values listed on the silk
screen next to the power connector.
9. Insert the local fuse into the power fuse slot. The power plug can be inserted into the power 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.
10.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.
