3.2 Power Supply and Hoist Control3.2.1 General(1) Check if voltage indicated on the hoist nameplatecorresponds to the power supply rating.(2) Single phase motors are factory connected foreither 220 VAC or 110 VAC.On dual voltage machines change plug and wiringaccording to drawing inside control box.Three phase machines are factory connected for220 VAC, 3 Ø.(3) It is important to note that SINGLE-PHASE motorsare more sensitive to overloading and voltage dropthan three phase motors.Therefore never exceed maximum rated load, andsee to it that the 110/220 VAC power supply isalways available.In case of difficulties have an electrician or qualifiedperson read voltage at motor terminal during liftingoperation. Especially for high lifting operations, whichrequire long cords, it is essential to use power cordsof sufficient size (see par. 3.2.3) to avoid excessivevoltage drop.(4) WARNING: NEVER OPERATE THE HOISTOR ANY OTHER ELECTRIC EQUIP-MENT IN A POTENTIALLY EXPLOSIVEATMOSPHERE: around distilleries, refineries,chemical plants, ship or silointeriors.Always obtain official approval before commencingoperations at these or similar locations.(2) In some cases, a booster transformer will be neededto compensate for power cord losses or low-sourcevoltage. If a booster transformer is needed, call supplier.(3) CAUTION: DO NOT OPERATE THE MOTORFOR ANY REASONS, IF THE MEAS-URED RUN VOLTAGE IS LESSTHAN THE MOTOR NAMEPLATERATING!(4) Always secure the powercord to the platform with astrain relief fitting andshackle (Fig. 7), so thecord weight will be off theconnector.(5) When finished for the day,make certain the powercord is disconnected at thehoist pigtail as well as atthe main outlet.(6) Be sure to ground all electricequipment. D onot use wire rope as aground!Fig. 6 Strain ReliefFitting3.2.2 Fuses / Circuit breakersIf connected to a circuit protected by a fuse, use Time-Delay-Fuse.Check if specification of fuses, which protect electricalequipment, corresponds to the amperage indicated onthe machine nameplate. The recommended service requirementsper hoist are:3.2.4 Hoist ControlControl (Fig. 7) is by– push-buttons, which automatically return intoSTOP-position, when not activated, and an– EMERGENCY STOP button.DO NOT fix push-buttons in run position.Single phase Three phase amps.110 V 220 V 30220 V – 203.2.3 Power Cords and Grounding(1) To prevent voltage drop exceeding the allowable10% we recommend to use at least #10, STO typepower cords, 600 VAC rating.To minimize voltage drop due to power cord lengthon high lifts, select an outlet at the halfway point toreduce the total power cord length on the job.Fig. 7Typical Hoist Control9
