General precautions
• This manual may contain some drawings with the
cover or protective shields removed for more
detail and clear explanation of the device. Make
sure to reassemble the device before operation.
• The information in this manual may be subject to
change without a previous notice in case of
modification or improvement, or changes in
specifications. Such modifications are denoted
by a revised manual number.
• Contact your Samsung representative or the
nearest Samsung sales office to order a copy of
this manual if it has been damaged or lost.
• Samsung is not responsible for any modification
of the product made by the user, since that will
void your guarantee.

This user’s manual uses (Danger), (Caution) or (Note) for the
safety precautions depending on the degree of precautions.
Safety precautions
Installation
• Before starting wiring or inspection, switch power off, wait for
more than 1 minutes, and check for residual voltage between
terminal P/B and N with a meter etc, to avoid a hazard of
electrical shock..
• Do not remove the operator from the main body.
It may cause an electric shock.
• When using the digital operator away from the main body, use the
separated operator(E7OPTR-S).
• Suitable for use in a circuit capable of delivering not more than
5kA rms symmetrical amperes.
DANGER: Wrong handling may cause a dangerous
situation, which can lead to death or a
severe injury.
!
CAUTION: Wrong handling may cause a dangerous
situation, which can lead to a severe
injury, slight injury, or damage to the
production, or faulty operation.
!
DANGER
!
Safety precautions
• Do not carry the inverter by holding the plastic parts, but hold the
heatsink.
The heat sink may fall and cause injury.
• Use nonflammable materials such as metal for the part where the
inverter is installed.
• When installing several inverters in a single enclosed space, install
a cooling fan to keep the ambient temperature below 45℃
• Cover the inverter during installation to protect it from metal
chip coming from drilling.
Wiring
• Always turn OFF the input power supply before wiring.
Otherwise, an electric shock or fire may occur.
• Wiring must be performed by qualified personnel.
• Always check if the bolts on the main circuit and control circuit
terminals are properly tightened.
• Turn ON the inverter only after completely assembling the covers.
Do not detach the cover when the power is ON.
Otherwise, an electric shock or fire may occur.
• Ground the ground terminal (200V & 400V class: ground to 100Ω
or less).
Otherwise, an electric shock or fire may occur.
CAUTION
!
DANGER

MOSCON E-7 User’s Manual

• 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.
CAUTION

Safety precautions
MOSCON E-7 User’s Manual

Maintenance and inspection
• Do not remove the digital operator from the unit since it carries
high voltages. Using the cable between operator and unit is also
prohibited, since it is very dangerous.
• Do not touch the terminals since some of them carry high
voltages and are extremely dangerous.
Otherwise, it may cause an electric shock.
• Do not remove the cover when power is being supplied to the
inverter. Always turn off the power to the inverter through the
MCCB when detaching the cover.
Otherwise, the charge remained in the capacitor may cause an
electric shock.
• After turning off the main circuit power supply, wait for a while
before maintenance or inspection since it may remain charged.
Otherwise, it may cause an electric shock.
• Maintenance, inspection, and replacement of parts must be done
only by authorized personnel.
Otherwise, it may result an injury or an accident.
• Remove all metal objects, such as watches and rings, before the
maintenance, inspection, and replacement of parts. Also, always
use grounded tools.
Otherwise, it may cause an electric shock.
• Always turn off the power supply before the inspection
Otherwise, it may cause an electric shock.
DANGER
!
Safety precautions
• Do not touch the COMOS IC in the control board directly.
Otherwise it can be damaged by static electricity.
• Do not change the wiring, or remove the digital operator or
connectors, during operation.
Otherwise, it may cause a personal injury.
