55

◎ If VFD is damaged, flooded or parts are missing, it cannot be installed or operated. Otherwise, equipment damage or personal injury may occur.

56

57

◎ Please hold the bottom of the product when installing and moving, and cannot only hold the shell to prevent smashing or breaking the VFD.

58

59

◎ VFD should be away from flammable and explosive objects, away from heat sources, and installed on flame retardants such as metals.

60

61

◎ When the VFD is installed in an electrical cabinet or other enclosure, install fans or other cooling equipment in the cabinet and set vents to ensure that the ambient temperature is below 40°C, otherwise the inverter may be damaged because the ambient temperature is too high.

62

63

◎ Before connecting cables, ensure that the rated voltage and phase number of the inverter are consistent with the input power voltage and phase number. Otherwise, fire or personal injury may occur.

64

65

◎ The AC input power can not be connected to the inverter output terminals U, V, W, otherwise the inverter will be damaged and cannot enjoy the warranty service.

66

67

◎ Do not test the voltage resistance of the inverter, otherwise it will cause damage to the VFD.

68

69

◎ The main loop terminal wiring and control loop wiring of the product should be routed separately or crossed vertically, otherwise the control signal will be interfered with.

70

71

◎ The wiring cable of the main loop terminal should use a wire nose with an insulating sleeve.

81

82

[[image:1762401041266-116.jpeg]]◎ Ground terminal must be grounded reliably. Otherwise, there is a risk of electrified VFD housing.

83

84

◎ Do not touch the main loop terminal. Do not connect the main loop terminal of the VFD to the housing. Otherwise, electric shock may occur.

85

86

◎ The connection terminals of the brake resistor are (+) and PB. Do not connect other terminals. Otherwise, a fire may occur.

87

88

◎ The VFD can be powered on after the wiring is completed and the cover plate is added. It is strictly prohibited to remove the cover plate when it is charged, otherwise it may lead to electric shock.

89

90

◎ When the VFD is configured with the function of automatic reset after failure or automatic restart after power failure, you must take safety measures in advance to protect the equipment system; otherwise, personnel may be injured.

91

92

◎ The "Run/Stop" button may fail due to a function setting. A separate emergency power off switch can be installed in the inverter control system, otherwise it may result in personal injury.
