8-1 HOW TO CONNECT WIRINGS

Methods of wiring units and connecting remote controller wiring

Wiring between units
Unscrew and remove the service lid.
Connect the wiring between units of matching number to the power supply terminal block (4P). And connect 
the ground wiring to the ground terminal.
When doing this, tie the wiring between units and the ground wiring using the included clamp (small) (5) and 
then firmly secure using the included clamp (small) (5) according to the figure.

(Refer to Fig. 20)

Remote controller wiring
Unscrew and remove the service lid.
Connect the remote controller wiring to the terminal block (5P).
When doing this, tie the remote controller wiring using the included clamp (small) (5) and then firmly secure
