Additional Information For Initial Start-up Only
This equipment is designed for indoor installation only.
Sheltered locations such as attics, garages, etc., gen-
erally will not provide sufficient protection against ex-
tremes in temperature and/or humidity, and equipment
performance, reliability, and service life may be ad-
versely affected.
Note:
Voltages listed are to show voltage range. However,
units operating with over- or under-voltage conditions
for extended periods of time will experience premature
component failure. Three phase system imbalance
should not exceed 2%.
