• Tighten all terminal screws of the main circuit and the control
circuit.
• Check if the voltage of the inverter rated voltage satisfies with the
AC power supply voltage.
Otherwise, it may cause fire or injury
• Do not perform withstand voltage test on the inverter. It may
damage the semi-conductor element.
• When wiring other devices read their manuals carefully. Samsung
is not responsible for any accident resulting from user’s
carelessness.
If not, it may cause injury or fire.
• Do not connect electromagnetic switches or contactors to the
output circuits.
• Never connect an AC power supply to output terminals U/T1,
V/T2, and W/T3.
Otherwise, it may damage the internal circuits of the inverter.
• Never short or ground output terminals: the output terminals
should not be touched with bare hands and also, the output wires
should not have contact with the inverter case
Otherwise, an electric shock or grounding may occur
•
Do not connect a phase advancing capacitor or LC/RC noise filter
to an output circuit.
Otherwise, it may damage the inverter or cause a fire.
• Do not connect an electromagnetic switch or MC to an output
circuit.
Otherwise, it will actuate the over current protective circuit in the
inverter.
• Do not disassemble the digital operator.
Otherwise, it may cause a personal injury.
CAUTION
!
Parameter setting
• Set the appropriate parameter. If not, it will not operate or trigger
the protection operation.
• Record the previous parameters (even though Moscon-E7 records
the information of the last parameter), the records can be useful
in case of malfunction or errors.
• When changing the parameters, make small change at a time
especially when controlling the motor parameter, changing the
V/f or max. output frequency. If not, it may damage the
inverter and motor.
