Wiring Primary Branch Box

WARNING

• 

When replacing or servicing any branch

boxes, you must disconnect all power.  This
can be done by disconnecting power at the
disconnect switch by the junction box and the
outdoor unit or tripping both breakers.

• 

Every wire must be connected firmly.

• 

No wire should be allowed to touch 
refrigerant tubing, the compressor or any   
moving part.

• 

Loose wiring may cause the terminal to over-
heat or result in unit malfunction.  A fire 
hazard may also exist.  Therefore, be sure all 
wiring  is tightly connected.

• 

Connect wires to the matching numbers of 
terminals.

Power Supply line 1 phase,
