Electrical Connections
4. Now, secure the MC cable to the electrical cover 
 by pushing the threaded end of the cable into the 
 hole and reinstalling the retaining nut previously 
 removed. Please refer to the images below. 
 Continue to do this for each of the MC cables 
 coming from each of the air handlers installed.  
5. Then, you will connect the wires to the terminal 
 block. Each wire should be numbered and 
 correspond with a connection port on the terminal
 block. Match up each wire with the correct port, 
 and firmly screw the u-lug of each wire to its 
 corresponding terminal. Now, screw the ground 
 wire into the bottom screw of the terminal block, 
 as shown in the image below. Continue to do this 
 with all of the MC cables from each of the air 
 handlers, using the wiring diagram for your system 
 on the previous pages as a guide, until they are all 
 connected to the condenser.  
6. Finally, reinstall the electrical wiring cover and
 secure it using by reinstalling the screws you 
 previously removed.
