Article 1
This article mainly introduces cautions for installation, wiring,
operation, operating conditions and electrical work. To avoid
any errors that may result in damage to equipment or injury to
personnel, do read carefully all of the instructions in this article.
Indications of Safety Symbols
To use and operate the inverter correctly, do read and clearly understand
the following symbols in this manual before installing and operating it, and
follow the instructions exactly.
WARNING:
This symbol calls your attention to avoid any incorrect
operation that can result in serious damage to the
equipment or death to personnel.
CAUTION:
This symbol calls your attention to avoid any incorrect
operation that can result in damage to the inverter or
other equipment.
Caution of electric
The ground terminal must be reliably, properly and independently grounded
to ensure security.
The electronic components inside the inverter are very sensitive to static.
Do keep your hands off the circuit board and never put foreign matter inside
the inverter before taking antistatic measures. Otherwise, there is an
equipment failure.
Do not touch any active components in the inverter, for high voltage remains
in it when the indicator light is ON after the power cut.
Cautions for Installation and connection
The installation and connection of inverter should be operated by qualified
electricians. Read this instruction manual in detail before installing and wiring.
Wait at least five (5) minutes after turning OFF the power supply before wiring.
Otherwise, there is the danger of electric shock.
Be sure that the main circuit is correctly wired. Three-phase 200V or 400V AC
input power must be connected to the terminals labeled R, S and T. Single
phase input power must be connected to terminals labeled L1 and L2. The
output power should be connected to terminals marked U, V and W. Otherwise,
there is serious damage to the inverter.
The output terminals (U, V, W) should be connected to the motor directly. Do
not install electromagnetic contactor, switch, capacitor or surge suppressor
between the terminal and the motor. Otherwise, it may result in inverter failure
and device damage.
Be sure to install the inverter on flame-resistant material such as a steel plate,
for heat will be produced during the running of inverter. The surface of plate must
be flat or even. Otherwise, the base of inverter might be easily broken.
Be sure to install an exhaust fan or other ventilation equipment in the case in
which the inverter is installed, so as to keep the ambient temperature less
than +40
.
