sure the outlet is properly grounded. Proper grounding helps protect the
system against damage from power surges caused by static discharges and
lightning. See "Appendix C: Grounding Requirements" before connecting
the control unit to the power source.
Once you are satisfied that the outlet is properly grounded, connect the
control unit to the ac outlet as follows:

unit.
Plug the other end of the cord into the ac outlet, allowing for a foot or so
of slack.
Set the power switch on the control unit to On.
The green power light on the control unit goes on.
The red warning light on the control unit blinks once, then goes off unless a malfunction
occurs.
The orange light on the power module goes on indicating that the outlet is properly wired
and grounded. If the orange light is off when the green light is on, the outlet is not
functioning, or may be miswired or improperly grounded. Contact a qualified electrician
immediately.
