The alternate (HI) setting further reduces the likelihood
of condensate in high humidity environments.
WARNING! Check the motor and motor wiring insulation before connecting the
ACH550 to line power. Follow the procedure in the ACH550-UH User's Manual on
page 1-23. Before proceeding with the insulation resistance measurements, check
that the ACH550 is disconnected from incoming line power. Failure to disconnect
line power could result in death or serious injury.
Note: For the remainder of the wiring (motor and control wiring) refer to the
ACH550-UH User's Manual.
