6.1 Line Voltage Wiring
WARNING! Risk of electrical fire and short circuit. Can cause property damage, injury or death. Select and
install the line side electrical supply wire and overcurrent protection device(s) according to the specifications
on the unit nameplate(s), per the instructions in this manual and according to the applicable national, state,
and local code requirements. Use copper conductors only. Verify that all electrical connections are tight. Unit
specific wiring diagrams are provided on each unit.
NOTICE
Risk of improper power supply connection. Can cause equipment damage and loss of warranty coverage.
Prior to connecting any equipment to a main or alternate power source (for example: backup 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. In general, 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.
NOTE: For acceptable and unacceptable power supplies, see Wye vs. Delta Connected Power Supply for ECFans on
page24.
Condenser rated voltage should be verified with available power supply before installation. Refer to the unit’s electrical
schematic and serial tag for specific electrical requirements.
