To connect the NetGuardian to a power supply:
1. 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 NetGuardian, before making your power connections.
2. Use the grounding lug to connect the unit to earth ground. The grounding lug is next to the symbol
. 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; then insert a battery line to the plug's left
terminal.
4. Insert a fuse into the fuse distribution panel and measure voltage. The voltmeter should read b11
and +18 (for +12VDC build option), –40 and –70VDC (for -48VDC build option) or -18 and -36VDC (-24VDC build
option).
5. The power plug can be inserted into the power connector only one way to ensure the correct polarity. Note that
the negative voltage terminal is on the left and the GND terminal is on the right.
6. Insert fuse into the Power A fuse slot. The power LED should be lit green. If the LED is red, the power connection
is reversed. To confirm that power is correctly connected, the front panel LEDs will flash RED and GREEN,
indicating that the firmware is booting up.
7. Repeat steps 1 -6 for Power B connector.
