The NetGuardian is powered by two screw terminal barrier plug power connectors.
Screw terminal barrier plugs
Note
: Always use safe power practices when making power connections. Be sure to remove fuses
from the fuse distribution panel, as well as the back of the unit, before making your power connections.
To connect the unit to a power supply:
1. Use the grounding lug next to the
symbol to connect the unit to earth ground.
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 the voltage by connecting the black cable onto the ground connector of your DVM and the
red cable onto the other connector of your DVM.
8. If the voltage does not read between the range displayed below the grounding lug, stop immediately.
Note
: The voltage range will depend on build and power input source. If you experience any issues with
powering your unit, contact DPS Telecom technical support at 559-454-1600 or
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.
