3. Now, use a Phillips screwdriver to pry the clip open as shown in
Figure 1. Insert the screwdriver into the screw head.
4. Next, find the wire with ring connectors on each end. Attach one ring
connector to the screw as shown in Figure 1. Place the washer on the
screw under the ring connector, and use the nut to fasten the
connection. Remove the Phillips screwdriver from the clip.
5. Now, turn your SpikeFree module upside-down. Notice that there are
two slots in the bottom of the surge protector — one on the side of the
protector that curves in, and the other on the side that curves out. See
Figure 2. Insert the metal clip into the slot on the side of the module
that curves out. (Using this slot will make the clip easier to remove
later.)
Note: If you have two or more SpikeFree modules connected
together, attach the metal clip to the end module as shown
in Figure 3.
6. Use a Phillips screwdriver to remove
the ground screw from the back of the
Fortress. (See Figure 4 to find the
ground screw.)
7. Place the ring connector on the ground
screw and reattach the screw to the
Fortress as shown.
3. Lights and Display
Fortress uses its lights and its display to let you know what it is doing. As you use the UPS, the
lights and display may change. This section shows you how to understand the UPS front panel.
3A. Lights
The UPS has three lights on the front panel: the green light, the yellow light, and the red
light. 120-volt models also have a small red Site Wiring Fault light above the DIP switches
on the back panel. The paragraphs below explain what each light means.
