Electrical Connections

Using the sealed AC nipple/wire assembly (3 wires), connect one end to the transformer leads, inside the enclosure, and the other end, to AC line voltage inside the junction box. Connect the white lead to neutral and the purple lead to AC line voltage (the input is universal 110 to 277 VAC). (See Figure 5).

Optional: For AC models used with DC remote power, the sealed DC nipple/wire assembly (2 wires) will also need to be installed. One end connects to the LED-STRIP leads, inside the enclosure, and the other end to DC input inside the junction box. Connect the red lead to positive, and the blue lead to the negative of the remote DC input (See Figure 5).

It depicts the connection to the LED strip and transformer, and emphasizes isolating primary wire connections from the charger.

Mounting

• For canopy mount: Attach the canopy backplate to the junction box using the junction box screws. Mount the frame and canopy assembly to canopy back plate by using the provided securement screw.
• For wall mount: Attach the frame to the junction box, using the junction box supplied screws.

Final Assembly

4. Reinstall the diffuser and the EXIT panel (if required, remove the appropriate chevron).
5. Install the lens by using the 6 tamper-proof screws. The o-rings have to be installed on the screw between the lens-legend and the frame as shown in Figure 12. The tamper-proof screws should be equally torqued to approximately 10 - 15 in-lbs (1.1 - 1.7 N-m).
6. Energize AC. Sign will illuminate.

Testing (Self-Powered Models)

Manual Testing

Operate the magnetic "test switch" by holding the provided magnet underneath the unit where indicated on the frame. The AC pilot lamp will go out, the legend will flicker, but remain lit. Remove the magnet. The AC pilot light will turn on, the legend will flicker but remain lit.

Automatic Testing

The unit will perform an automatic self-test of 30 seconds every 30 days, 60 seconds every 60 days, and a 90-minute self-test once a year.

Nexus Models

Refer to Figure 6 for the wiring of Nexus models. These units can accept an input voltage of 120 or 277 VAC:

• 120 VAC: Connect the black (120 VAC) lead and white (neutral) lead to the building utility. Insulate the orange wire.
• 277 VAC: Connect the orange (277 VAC) lead and white (neutral) lead to the building utility. Insulate the black wire.

Feed excess wire into the junction box.

Nexus Wired Models

Route the double insulated data cables through the liquidtight fitting previously installed on the frame and strip 1 inch (25mm) of the double insulation. The two cables are identical and both contain 2 wires of different colors: "color A" and "color B". Gather the "color A" wire from each cable, and connect them to the same pole on the terminal block. Gather the "color B" wire from each cable, and connect them to the other pole on the terminal block. The result must be 2 wires of the same color in each pole on the terminal block. Leave a minimum of one inch (25mm) between the live voltage cabling and the unsheathed low voltage data cabling (Refer to Figure 9).
