Anleitung Zusammenfassung
The qualified installer or agency must use factory--authorized kits or accessories when modifying this product. Refer to the individual instructions packaged with the kits or accessories when installing. Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloths for brazing operations and have a fire extinguisher available. Read these instructions thoroughly and follow all warnings or cautions attached to the unit. Consult local building codes and appropriate national electrical codes (in USA, ANSI/NFPA70, National Electrical Code (NEC); in Canada, CSA C22.1) for special requirements. It is important to recognize safety information. This is the safety--alert symbol . When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury. Understand the signal words DANGER, WARNING, CAUTION, and NOTE. These words are used with the safety--alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices, which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation. ELECTRICAL HAZARD Failure to follow this caution may result in personal injury or product and property damage. The electrical data contained in this document is only for use with 48TC size 16 units which display a “3” in the 13th position of the 17 digit model number as displayed on the unit’s nameplate. See Fig. 1 for location of the unit’s nameplate. See Fig. 2 for details of the 17 digit model number. ! CAUTION ELECTRICAL SHOCK HAZARD Failure to follow this warning could cause personal injury or death. Before performing service or maintenance operations on unit, always turn off main power switch to unit and install lockout tag. Unit may have more than one power switch. !

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 percentage of voltage imbalance. max voltage deviation from average voltage % Voltage Imbalance = 100 x average voltage Example: Supply voltage is 230-3-60 AB = 224 v BC = 231 v AC = 226 v (224 + 231 + 226) 681 Average Voltage = = 3 3 = 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. 4 % Voltage Imbalance = 100 x 227 = 1.76% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. IMPORTANT: If the supply voltage phase imbalance is more th...
