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

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.

• Do not inspect components unless inside “Charge” lamp is off.

It may cause an electric 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).

• Be careful not to be damaged the inverter in delivering.

• Do not carry the inverter by holding the plastic parts, but hold the
heat sink.
Otherwise, 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.

2.3.3 Controlling the ambient temperature

To maintain the optimum condition, the inverter should be installed at
the ambient temperature of –10℃~40℃. If installed in a closed
environment (e.g. enclosed panel), install a cooling fan or air conditioner
to avoid any extreme temperature increases and to maintain the internal
air temperature within the range.

• If installed in a closed environment (e.g. enclosed panel), we

strongly recommend the inverter to be installed on a vertical space.

If it is installed on a horizontal space, its internal temperature may

increase excessively and thus, reducing its durability.

CAUTION

3.5 Connections to peripheral devices

Examples of connections between the Moscon-E7 and peripheral
devices are shown in the figure below

.

Figure 3.4 Peripheral devices

Power supply

Follow the specification on power supply.

Molded-case circuit breaker or leakage current
circuit breaker

Large inrush current flows when power is supplied thus,
use appropriate breaker, which is tolerant to high
frequency.

Magnetic contactor

Installed to remote control the supply/block of the
power. Frequent start/stop of the inverter through this
device reduces durability of the inverter. Install the
surge absorber on the coil.

AC/DC reactor for power factor improvement

AC/DC reactor is required when improving the power
factor or when the inverter is connected to a large­capacity power transformer whose capacity is 600kVA or
more. If not, invert may be damaged.

Input noise filter

Install it close to the inverter to reduce the noise from the
wire.

Input wiring

Inappropriate wiring damages the inverter. Do not
connect input power R, S, and T to output U/T1, V/T2,
and W/T3. Keep enough distance between the control
signal line and main circuit to prevent the effect of noise.

Installation area

Install in a place free from gas and dust. Maintain the
ambient temperature within the specified range.

Output noise filter

Install the output noise filter close to the inverter to
reduce the noise from output wire of the inverter.

Motor

Follow the specification when running the motor.

Grounding

Ground the inverter and motor to prevent any electric
shock.

Wiring between the inverter and motor

Keep the wire between the inverter and motor short.
If not, it may decrease the carrier frequency.
Leakage current from the cable affects the inverter and
other peripheral devices.

3.6 Wiring the main circuits

3.6.1 Wiring on the input side of main circuit

3.6.1.1 Installing a molded-case circuit breaker

• Always connect the input power terminals (R/L1, S/L2 and T/L3) via

an appropriate MCCB.

•

Large inrush current flows when power-up, thus, use appropriate

breaker. Use the one that is tolerant to high frequency.

• MCCB with a capacity of 1.5 to 2 times greater than the rated current
of the inverter should be used.

• When one MCCB is used for more than one device (e.g. inverter), the
sequence must be set up so that the power supply is turned off by a
fault output.

3.6.1.2 Installing a magn etic contactor (MC)

• The inverter is able to use without the magnetic contactor of power
supply side.

• In case of installing the magnetic contactor to input power supply in
order to prevent an accident occurred by the automatic restart
operation after the recovery from a power interruption, frequent
start/stop of the inverter through this device reduces durability of the
inverter.

• When the digital operator is used, unless the inverter operation mode is
set to the automatic start operation, it cannot be automatically started
after the recovery rom a power interruption.

• Install the surge absorber on the coil.

• Two options are available when the inverter is connected to a large­capacity power transformer whose capacity is 600kVA or higher:

Figure 3.5 Reactor installation

• If not, inverter may be damaged due to an excessive peak current flow
through the input power circuit.

• AC reactor/DC reactor also can be used to improve the power factor
on input power supply side.

supply are irrelevant.

3.6.1.5 Installing a surge absorber

• A surge absorber must be used for inductive loads near the FARA
MOSCON-E7. Otherwise, it may damage the devices or cause
malfunctioning.

• These inductive loads includes:

- MC,

- Electromagnetic relay,

- Solenoid valves and solenoids,

- MCCB

3.6.2 Wiring on the output side of main circuit

3.6.2.1

Precautions when wiring on the output side of main circuit

• Never connect a 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 wires should not have contact with the inverter heatsink.

• 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 overcurrent protection circuit of the

inverter.

3.6.2.2 Connecting the inverter and motor

• Connect output terminals U/T1, V/T2, and W/T3 to motor wires U, V,
and W respectively.

•

Check if the motor rotates in correct direction according to the
command. If not (motor rotating in reverse with the forward run
command), switch any of two output terminals to each other and
reconnected them.

3.6.2.3 Installing a noise filter on the output side

Install a noise filter to reduce radio noise and inductive noise.

3.6.3 Dealing with inductive noises

• As mentioned previously, noise filter can be used to prevent the
inductive noise generated on the output side.

• As an option, cables can be routed through a grounded metal pipe to
prevent inductive noise.

• If the metal pipe and the signal line are at least 30cm apart, the
inductive noise can be considerably reduced

.

Figure 3.8 Dealing with inductive noise

3.6.4 Dealing with radio interference (RFI)

• Radio noise is generated from the inverter as well as the input/output
lines.

• The radio noise can be reduced by installing the noise filters on both
input and output sides, and also installing the inverter in an enclosed
and grounded steel box.

• Make the cable between the inverter and motor as short as possible.
