POWER CONNECTION — Make line voltage connection
by connecting the incoming line voltage wires to the L side
of the CC terminal as shown in Fig. 13. See Table 3 for
correct wire and maximum overcurrent protection sizing.
SUPPLY VOLTAGE — Operating voltage to unit must be
within voltage range indicated on unit nameplate.
On 3-phase units, voltages under load between phases must
be balanced within 2%. Use the following formula to deter-
mine the percentage voltage imbalance:
% Voltage Imbalance
Example: Supply voltage is 460-3-60.
AB = 452 volts
BC = 464 volts
AC = 455 volts
Determine maximum deviation from average voltage:
(AB) 457 – 452 = 5 v
(BC) 464 – 457 = 7 v
(AC) 457 – 455 = 2 v
Maximum deviation is 7 v.
Determine percent voltage imbalance.
= 1.53%
This amount of phase imbalance is satisfactory as it is
below the maximum allowable 2%.
Operation on improper line voltage or excessive phase
imbalance constitutes abuse and may cause damage to electri-
cal components.
NOTE: If more than 2% voltage imbalance is present, contact
local electric utility.
220-VOLT OPERATION — All 220-240 volt units are factory
wired for 208 volts. The transformers may be switched to
220-volt operation by switching the red (220 volt) wire with
the orange (240 volt) wire at the TB1-1 terminal for single-
phase and TB1-3 for 3-phase.
