WARNING
Building Electrical Service Inspection
This unit is designed for 3-phase operation. DO NOT OPERATE
ON A SINGLE PHASE POWER SUPPLY. SEE THE PRECEDING
WARNING. Measure the power supply to the unit. The supply
voltage MUST be in agreement with the unit nameplate power
requirements and within the range shown in Table 6.

Table 6.
Voltage Balance The supply voltage shall be unbalance (phase to
phase) within 2%. To calculate the percentage of voltage unbalance
use the following formula:
Percentage Max Voltage Deviation From Avg Volt-
age Unbalance = 100 x Average Voltage
Example
. L1 – L2 = 220 V
L2 – L3 = 216 V
L1 – L3 = 213 V
Avg. Voltage = (220+216+213) / 3
= 649 / 3
= 216
Max. Deviation from Avg. = 220 – 216 = 4
% Voltage Unbalance = 100 x (4 / 216)
= 400 / 216
= 1.8%
