FLA -- Full Load Amps

HACR -- Heating, Air Conditioning and Refrigeration

OFM -- Outdoor (Condenser) Fan Motor

RLA -- Rated Load Amps

*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v or

600 v. If power distribution voltage to unit varies from rated heater voltage,

heater kW will vary accordingly.

l-Fuse or HACR circuit breaker.

NOTES:

1. In compliance with NEC requirements for multimotor and combination load

equipment (refer to NEC Articles 430 and 440), the overcurrent protective

device for the unit shall be fuse or HACR breaker. Canadian units may be

fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage is

greater than 2%. Use the following formula to determine the percent of

voltage imbalance.

% Voltage Imbalance

= 100 x max voltage deviation from average voltage

average voltage

Example: Supply voltage is 230-3-60.

A B c AB = 224v

BC = 231 v

AC = 226 v

Average Voltage -

224 + 231 + 226

681

=--

= 227

Determine maximum deviation from average voltage.

(AB) 227 - 224 = 3 v

(BC) 231 - 227 = 4 v

(AC) 227 - 226 = 1 v

Maximum deviation is 4 v.

Determine percent of voltage imbalance.

% Voltage Imbalance = 100 x 22"_-

= 1.76%

This amount of phase imbalance is satisfactory as it is below the maximum

allowable 2%.

I IMPORTANT: If the supply voltage phase imbalance is more than 2%, 1

contact the local electric utility company immediately.
