NOTICE
Risk of improper power-supply connection. Cancause equipment damage and loss of warranty coverage.
Prior to connecting any equipment to a mainor alternate power source (for example: back-up generator
systems) for start-up, commissioning, testing, or normal operation, ensure that these sources are correctly
adjusted to the nameplate voltage and frequency of all equipment to be connected. Ingeneral, power-source
voltages should be stabilized and regulated to within±10%of the load nameplate nominal voltage. Also, ensure
that no three-phase sources are single-phased at any time.
See transformer label for primary tap connections. Installer will need to change transformer primary taps if
applied unit voltage is other thanpre-wired tap voltage.
NOTE: Seal openings around piping and electrical connection to prevent air leakage. Failure to do so
could reduce the unit’s cooling performance.
The electrical and unit-to-unit connections are described inthe submittal documents included inthe Submittal Drawings on
page 109.
