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

max voltage deviation from average voltage

= 100 x

average voltage

Example: Supply voltage is 460-3-60.

AB = 452 volts

BC = 464 volts

AC = 455 volts

452 + 464 + 455

Average Voltage =

3

1371

=

3

= 457

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.

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.

% Voltage Imbalance = 100 x

7

457

= 1.53%

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
