correctly, the LED by the connector will light GREEN. If the polarity of the power feed is reversed, the
LED will not illuminate.
6. Repeat Steps 2–4 for Power Connector B.
7. Reinsert the fuse to power the NetGuardian. The front panel LEDs will flash RED and GREEN.
To connect the NetGuardian to a power supply using a WAGO connector, follow these steps:
The Grounding Lug on the back of the unit provides a permanent connection to earth
ground when connected. The Grounding Lug must be used in order to comply with
standards.
WARNING!
1. Remove the 2 fuses (A& B) from the back panel of the NetGuardian. Do not reinsert the fuses until all
connections to the unit have been made.
2. Remove the WAGO power connector. 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 –48V
terminal is on Slots 1 and 3 and the GND terminal is on Slots 2 and 4.
3. Use the grounding lug to connect the unit to earth ground. The grounding lug is next to the
the eyelet of the earth ground cable between the two bolts on the grounding lug (Ground cable not included).
4. Insert a battery ground into the power connector plug's slots 2 and 4 by pushing down on top of the
appropriate slot of the WAGO connector with a screwdriver and inserting the wire into the slot, then releasing
the screwdriver. Insert a –48 VDC line to the plug's slots 1 and 3 using the same method as before.
