1. Security
Danger！
★Converter will be installed in the place, where the absence of flammable and explosive gas was strictly
prohibited, else may cause to an explosion.
★Only can the professionals operate the converter in installation, wiring operating and maintenance,
otherwise may be to endanger the property and the personal safety.
★The converter ground terminal PE( ) must be reliable grounding (ground impedance must less than
4Ω), otherwise it may endanger the personal safety.
★The common terminal（CM）of internal power in the converter is not allowed to short circuit with the
zero power line, otherwise it will damage the converter and the property.
★Before putting power on the converter, it must be sure that the wiring is correct and the cover board is installed
well.
★After the converter is power on, strictly forbid to touch the terminals electrified. Otherwise it will
jeopardize the personal safety.
★Before wiring and maintenance, must turn off the power supply. Otherwise it will also jeopardize the
personal safety.
★In the period (10 minutes) of turning off the power on the converter, or when the voltage of the DC bus
is larger than 36V，please do not carry out any maintenance operations or touch the internal circuitry and
devices, otherwise it will also jeopardize the personal safety.
Warning！
●Before putting power on the converter, must recognize that the input supply voltage of converter is
right, otherwise it will damage the converter, and even to cause fire disaster.
●Don’t drop the screwdriver, screw or other metal objects into the converter. Otherwise it will damage
the converter and may also cause fire disaster.
●Do not install the converter under the sunlight or close up the cooling holes on the converter. Otherwise,
it will reduce output power of the converter.

●Strictly prohibit connecting the input power line to the terminals U、V、W、U1、V1 and W1. Otherwise
it will damage the converter and may cause fire disaster.
●The wiring line of control loop should be separated far from the power line each other; otherwise it may
affect the normal status of the converter or other devices.
Pay Attention to the Following Items,
◆Before operating of the converter please read this manual carefully.
◆The storage and installation of the converter must avoid the environment with strong vibration, strong
corrosion, high dust, high temperature and high humidity.
◆Must carry out regular checks whether or not the input and output wiring of the converter is correct
and the other electrical equipments are aging.
◆Electrical insulation strength must be checked before installing and operating the converter.
◆When the motor is frequently used in the operation with low-speed, additional cooling measures must
be taken to the motor.
◆Do not connect variable resistors and capacitors to the converter output trying to improve the power
factor. If you need to install circuit breaker between the output of the converter and the motor, you have to
ensure that the circuit breaker of the converter only acts at the zero output current.
◆The protection level of the YTB-S-LT converter is IP20.
◆After using the converter for 1 to 3 months, cleaning treatment to the internal parts and the radiator is
recommended. If the converter is not used for a long time, it is needed to turn power on some time in an
interval of certain period (one month is recommended).
