Double Mount Installation (continued)

4.  Feed wiring through base and pole - 

Take the wiring coming from the switch box and begin to feed it through the center of the 

base of the mounting assembly until it emerges from the hole in the center of the clock housing. Make sure there is roughly 1.5’ of 

wiring coming from the switch box. Perform this task for both clocks. 

5.    Snap and screw base to metal mounting bracket - 

Snap the base to the metal mounting bracket by first making contact with 

the lip in the upper side of the base and the metal mounting bracket. When the base has been snapped onto the bracket, take  

the two (2) 6-32 x 1/2” pan head screws that originally came installed on the base and screw them back into the two holes on the  

underside of the base to secure the base to the metal mounting bracket.

6.    Connect switch box wires to clock harness - 

Take the wiring harness supplied with the clock and make all necessary     

        connections between the wiring harness and the switch box wires using wire nuts. Perform this task for both clocks.

7.     Plug and secure wiring - 

Loosen and slip excess wiring through provided wire clamp (comes attached to each housing) and  

        tighten the clamp. After securing excess wiring, connect the wiring harness into the appropriate connector on the back of the       

        display board. Perform this task for both clocks. (See the Wiring and Jumper Settings on page 9).

8.    Mount display board to housing - 

 Using the four (4) self tapping, 6-19 x 1/2" flat head screws supplied in the assembly kit,    

        take the display board and screw it to the front side of the clock housing (4 screws per clock).

9.   Snap on filter - 

Take the red filter bezel and snap it on to the front side of each clock housing.

10.   Snap on frame - 

Take the gray frame and snap it on to the front side of each clock housing.
