Electronic Expansion Valve unit and
the Vertical Air Handling unit. The
power source is supplied from the
Vertical Air Handling unit.
2. Connect the wiring to L1 and L2 on
the power supply terminal block
(X11M). Also connect the ground
wire to the ground terminal. Take the
wiring and the ground wire into the
unit through the provided cabling
