Subject to alteration.

Before commencing the installation

• Disconnect the power supply of the device.

• Ensure that devices cannot be accidentally retriggered.

• Verify isolation from the supply.

• Ground and short-circuit.

• Cover or enclose neighbouring units that are live.

• Follow the engineering instructions (IL) of the device

concerned.

• Only suitably qualified personnel in accordance with

EN 50110-1/-2 (VDE 0105 Part 100) may work on this device/

system.

• Before installation and before touching the device ensure

that you are free of electrostatic charge.

• The functional earth (FE) must be connected to the

protective earth (PE) or to the potential equalizing.

The system installer is responsible for implementing this

connection.

• Connecting cables and signal lines should be installed so

that inductive or capacitive interference do not impair the

automation functions.

• Install automation devices and related operating elements

in such a way that they are well protected against uninten-

tional operation.

• Suitable safety hardware and software measures should

be implemented for the I/O connection so that a cable or

wire breakage on the signal side does not result in

undefined states in the automation device.

• Ensure a reliable electrical isolation of the low voltage for

the 24 V supply. Only use power supply units complying

with IEC 60364-4-41 or HD 384.4.41 S2 (VDE 0100 part 410).

• Deviations of the mains voltage from the nominal value

must not exceed the tolerance limits given in the technical

data, otherwise this may cause malfunction and

dangerous operation.

• Emergency-Stop devices complying with IEC/EN 60204-1

must be effective in all operating modes of the automation

devices. Unlatching the emergency switching off devices

must not cause restart.

• Built-in devices for enclosures or cabinets must only be

run and operated in an installed state, desk-top devices or

portable devices only when the housing is closed.

• Measures should be taken to ensure the proper restart of

programs interrupted after a voltage dip or failure. This

should not cause dangerous operating states even for a

short time. If necessary, emergency switching off devices

should be implemented.

• Wherever faults in the automation system may cause

damage to persons or property, external measures must

be implemented to ensure a safe operating state in the

event of a fault or malfunction (for example, by means of

separate limit switches, mechanical interlocks, etc.).

• During operation, and depending on their degree of

protection, variable frequency drives may have live,

uninsulated, moving, and/or rotating parts, as well as hot

surfaces.

• The impermissible removal of the required cover,

improper installation or incorrect operation of the motor or

variable frequency drive can cause the failure of the

device and serious injury and/or material damage.

• Comply with all applicable national accident prevention

regulations (e.g. BGV A3) when working with energized

variable frequency drives.

• The electrical installation must be carried out in

accordance with the relevant regulations (e.g. with regard

to cable cross sections, fuses, PE).

• All transport, installation, commissioning and mainte-

nance work must only be carried out by trained personnel

(observe IEC 60364, HD 384 or DIN VDE 0100 and national

accident prevention regulations).

• If applicable, systems in which variable frequency drives

are installed must be equipped with additional monitoring

and protective devices in accordance with the applicable

safety regulations, e.g., the German Equipment and

Product Safety Act, accident prevention regulations, etc.

Making changes to the variable frequency drives by using

the operating software is allowed.

• Keep all covers and doors closed during operation.

• When designing the machine, the user must incorporate

mechanisms and measures that limit the consequences of

a drive controller malfunction or failure (an increase in

motor speed or the motor?9s sudden stop) so as to prevent

hazards to people and property, e.g.:

– Additional stand-alone devices for monitoring parame-

ters that are relevant to safety (speed, travel, end

positions, etc.)

– Electrical and non-electrical safety devices (interlocks

or mechanical locks) for mechanisms that protect the

entire system

– Due to the possibility of there being capacitors that are

still holding a charge, do not touch live device parts or

terminals immediately after disconnecting the variable

frequency drives from the supply voltage. Heed the

corresponding labels on the variable frequency drives

1.1 Standards

EMS2…-SWD Electronic motor starter 10/19 MN120008EN www.eaton.com 5

1 General – EMS2-…-SWD electronic motor starter

1.1 Standards

In addition to the standards in accordance with EN 60079 / VDE 165-1,

separate standards for the corresponding types of protection apply to the

protection of motors in potentially explosive atmospheres.

Motors with type of protection for potentially explosive areas,

“increased safety”

The standard EN 60079-7 requires additional measures in the case of motors

with the type of protection for potentially explosive areas, “increased

safety”.

These measures ensure, with a high degree of certainty, that impermissible

high temperatures, sparks and electric arcs are prevented on motors where

these would not usually occur during normal operation.

The motor protection devices for this, which themselves are not located in a

potentially explosive area, must be certified by an accredited admission

office.

Motors in potentially explosive dust-air mixtures

For motors in potentially explosive dust-air mixtures, the standard

EN 60079-14 specifies additional measures.

Directive 2014/34/EC (ATEX) on the approximation of the laws of the

Member States concerning devices and protective systems intended for use

in potentially explosive areas has been in force since 20.04.2016.

1 General – EMS2-…-SWD electronic motor starter

1.2 Safety directives

6 EMS2…-SWD Electronic motor starter 10/19 MN120008EN www.eaton.com

1.2 Safety directives

1. The device executes a function diagnosis when the drive is switched on

or is in the switched on state. In addition, an authorized electrician or a

skilled worker who is well acquainted with the relevant standards can

conduct the “Motor overload protection” safety function test. For this

test, the drive must be operated withright or left rotation (forward or

reverse running), and the current flow in a conductor is interrupted

(e.g. by removing the fuse in the L1 or L3 phase). The EMS2 then

switches off the drive within 1.5 to 2 s. The LEDs for right or left rotation

go out, and the ERR-LED and the reply output are set and the confirma-

tion can be retrieved via the bus.

2. The device is an associated item of equipment.

Do not install the device in potentially explosive areas. When installing

and operating associated equipment, the applicable safety directives

must be observed.

3. When using devices with 230 V AC control, always use the same phase

for the control supply voltage and the control inputs.

4. If you use the “Automatic RESET” mode, the drive is switched on again

after the cooling time has expired - if a control signal is still present.

The cooling time is 20 minutes. For applications in the Ex-protection

area, automatic restart is not permitted.

5. For safety technical data, please refer to this document and certificates

(EC type examination certificate and other approvals if appropriate).

6. Electronic motor starters are not allowed to operate with variable

frequency drives.

7. For emergency stop applications, the machine must be prevented from

restarting automatically by a higher-level control system.

1.3 Device overview EMS2-…-SWD

EMS2…-SWD Electronic motor starter 10/19 MN120008EN www.eaton.com 7

1.3 Device overview EMS2-…-SWD

EMS2-…-SWD series electronic motor starters serve to switch and protect

three-phase asynchronous motors.

Depending on the version, the following functions are available:

• Direct starter (DO = Direct Online)

• Reversing starter (RO = Reverse Online)

• Motor protection

• Overload protection

• Phase failure

• Phase imbalance

• Category 3 controlled stop

PL e DIN EN ISO 13849, SIL 3 IEC 61508

The compact devices contain the required interlocks which are necessary for

the specified functions in order to reduce the wiring.

The supply of the device as well as the actuation of the operating direction

takes place via the internal SmartWire-DT (SWD) interface. In addition, the

motor starter uses this interface in order to provide additional information for

a superordinate controller.
