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.
