+12 or +24 VDC Sensor Power Supply

You can order your NetGuardian G5 with an optional +12 VDC or +24 VDC sensor power supply. (See Figure
6.10.1.) This provides a convenient way to connect an auxiliary sensor to a robust battery power supply.
The two-pin connector for the sensor power supply is a barrier plug connector similar to the main power
connector.
To power an external sensor, follow these steps:
1. Remove the 1/4 amp fuse from the sensor power supply on the back panel of the NetGuardian. (See
Figure 6.10.1.) Do not reinsert the fuse until all power connections to the external sensor have been
made.
2. Remove the power connector plug from the sensor power supply. Note that the plug can be inserted into
the power connector only one way — this ensures that the barrier plug can only be reinserted with the
correct polarity. Note that the positive terminal is on the left and the negative terminal is on the right.
3. Connect the appropriate leads to each of the plug's screw terminals and tighten the screws.
4. Push the power connector plug firmly back into the sensor power supply connector.
5. Reinsert the fuse to power the external sensor.
