Refer to Fig. 20-25 for power wiring connections. Utilize field-supplied wirenuts and '/4-in. insulated female quick-connects for making power wiring connections. Wrap wirenuts with waterproof tape to prevent them from loosening and ensure watertightness. NOTES: 1. On 220 v, 50 Hz units, disconnect the black wire connected to capacitor 1. On 400 v, 50 Hz units, disconnect blue wire connected to capacitor 1. Cap wire with a wirenut (50TJ008-014 only). 2. See wiring diagram on unit for more details. 38AQS008 AND 50LJQ008,012 UNITS - Power wiring must comply with all local and National Electrical Code (NEC) requirements. Refer to Fig. 26-28 for power wiring connections. Utilize field-supplied wirenuts and Vi-in. insulated female quick-connects for making power wiring connections. Wrap wirenuts with waterproof tape to prevent them from loosening and ensure watertightness. See wiring diagram on unit for more details. Step 5 — Install Field-Fabricated Wind Baffles and Brackets A WARNING To avoid the possibility of electrical shock, open all disconnects before installing or servicing this accessory. Wind baffles must be field-fabricated for all units to ensure proper cooling cycle operation at low-ambient temperatures with Motormaster III controls. See Fig. 29 and 30 for number and sizes of baffles required and for baffle details. Use 20-gage (1 mm) galvanized sheet metal or similar corrosion-resistant material for the baffles. Use field-supplied screws to attach baffles to unit. Screws should be Vi-in. (6.3 mm) diameter or larger. Drill required screws holes for mounting the baffles. A CAUTION To avoid damage to refrigerant coils and electrical components, use extreme care when drilling screw holes and screwing in fasteners. Step 6 — Restore Power To Unit - When all electrical connections have been made, ensure they are tight and correct. 1. Restore power to the unit. 2. Check the phase sequence indicator on the Motormaster III control. It should not be lit. If lit, turn off power and reverse LI (black) and L2 (yellow) power leads. See Fig. 3. 3. With phasing on Motormaster III control correct, make sure that the fan motors are rotating in the proper direction. If fan rotation is backwards, shut off power. Reverse the supply power leads between the Motormaster III control and the condenser fan motor to correct rotation. 4. Reinstall control box cover. 5. Reinstall unit access panel. 6 jQ ¡o qO I I Oj SENSOR LOCATION RETURN BEND END 48/50HJ008 RETURN BEND END 48/50TJ008 <£? + ♦ 4 + q0 .V :: ♦ • + 1 q0 + I + £ + + I q0 .V :: 00 .u A + • f. 2r i M i <2 qO + • ♦ • Jo • + + • + 00 -V + V + + qD + 0 RETURN BEND END D1=T11D..
