Important information
Installers should read and understand the instructions in this guide prior to installing, operating and maintaining
the soft start. The following symbols may appear in this guide or on the soft start to warn of potential hazards
or to draw attention to certain information.
Dangerous Voltage
Indicates the presence of a hazardous voltage which could result in personal injury or death.
Warning/Caution
Indicates a potential hazard. Any instructions that follow this symbol should be obeyed to avoid possible
damage to the equipment, and personal injury or death.
Protective Earth (Ground)
Indicates a terminal which is intended for connection to an external conductor for protection against
electric shock in case of a fault.
Caution Statements
The examples and diagrams in this manual are included solely for illustrative purposes. The information
contained in this manual is subject to change at any time and without prior notice. In no event will responsibility
or liability be accepted for direct, indirect or consequential damages resulting from the use or application of this
equipment.
EGS Series soft starts contain dangerous voltages when
connected to the mains supply. Only qualified personnel
that have been completely trained and authorised, should
carry out installation, operation and maintenance of this
equipment.
Installation of the soft start must be made in accordance
with existing local and national electrical codes and
regulations and have a minimum protection rating.
It is the responsibility of the installer to provide suitable
grounding and branch circuit protection in accordance
with local electrical safety codes.
This soft start contains no serviceable or re-usable parts.
The STOP function of the soft start does not isolate
dangerous voltages from the output of the soft start. An
approved electrical isolation device must be used to
disconnect the soft start from the incoming supply before
accessing electrical connections.

Mounting
Fix the unit to a flat, vertical surface using the mounting holes (or slots) on its base-plate. The mechanical outline
diagrams, shown on Page 4, give the dimensions and mounting hole positions for each model. Ensure that:
The orientation of the unit has the ‘TOP’ uppermost.
The location allows adequate front access.
You can view the touchscreen.
Do not install other equipment that generates significant heat close to the soft starter.
Requirements for an Enclosure
For a typical industrial environment, an enclosure would provide the following:
A single location for the unit and its protection/isolation switch-gear
The safe termination of cabling and/or busbars
Means to effect proper air flow through the enclosure
Enclosure Ventilation
When fitting EEC’S EGS Series into a cabinet, ensure proper heat dissipation. The formula below can help provide
approximations of the space required. Note: These would not be required for any NEMA 1 / IP21-41 application.
Starting
Watts (EGS Soft Start) = start current(A) x start time(s) x number of starts per hour/1800
Running
Watts (EGS Soft Start) = 0.4 x running amps
Use the following formula to determine the fan requirement. An allowance has been incorporated into the
formula so that the figure for Q is the air delivery in the fan suppliers’ data.
Q = (4 x Wt / (Tmax-Tamb))
Q = Volume of air (cubic metres per hour-m3/h)
Wt = Heat produced by the unit and all other heat sources within the enclosure (Watts) Tmax = Maximum
permissible temperature within the enclosure (40°C for a fully rated EGS Soft Start
Tamb = Temperature of the air entering the enclosure (°C) [to work in CFM, substitute °F for °C. Q is now in CFM]
Altitude De-rate
Altitude above sea level 1000m (3281ft). Above 1000m de-rate by 1% of EGS Soft Start i.e. per 100m (328ft) to
a maximum altitude of 2000m (6562ft).
Ambient Temperature De-rate
-20°C (-4°F) to 40°C (104°F). Above 40°C de-rate linearly by 2% of EGS Soft Start i.e. per °C to a maximum of 60°C
(140°F).

Handling
The EGS Series soft starter range comprises 3 frame sizes, with various weights and dimensions. See pages 5-7
for further information.
Prior to installing the EGS unit, the installer should carry-out a risk assessment. If considered appropriate, a
suitable handling device should be used.
Do not lift the EGS Soft Start unit by attachment to the 3-phase terminal connections or busbars.
WARNING
HANDLING AND LIFTING HAZARD
Ensure the area below any equipment is clear of all personnel and property.
Failure to follow this practice may result in death, serious injury, or damage to equipment.
Accessories
The following accessories have been developed and tested for use with the EGS Soft Start range of soft starts:
EGS-RKP Remote keypad for EGS-017A to EGS-361A. Provides remote functionality for up to 32 soft starter units.
EGS-ACU 100Vac – 240Vac power supply. Provides mains voltage control power and digital control functionality.
For use with EGS-017A to EGS-361A.
EGS-FS1 Cooling fan accessory for EGS-017A to EGS-065A only. Increases the number of starts per hour (see
page 19).
EGS-FS2 Cooling fan accessory for EGS-080A to EGS-195A only. Increases the number of starts per hour (see
page 19).

Warnings
Isolation
Caution: EGS Series uses semiconductor devices in the main circuit and is not designed to provide
isolation. For this reason, isolation means must be installed in the supply circuit in accordance with the
appropriate wiring and safety regulations.
Electrical Control Supply Requirements
All electrical connections are made to power input and output terminals, control terminals and an earth
stud.
Fuse Protection
The Mains Supply and the Control Supply each require protection. Although all units have electronic
overload protection for the Soft Starter, the installer should always fit fuses, for motor protection,
between the unit and the Mains Supply, not between the unit and the motor. Semiconductor fuses can
be supplied as an option for short-circuit protection of the semiconductors. These fuses must be fitted
externally to the EGS Series chassis to comply with certain standards. It is the responsibility of the
installer and system designer/specifier to ensure that the required standards or regulations are not
affected by so doing.
Safety
EGS soft starters contain hazardous voltages when connected to the electrical power supply. Only
qualified personnel who are trained and authorized should carry out installation, operation and
maintenance of this equipment. Refer to and carefully follow all of the ‘Warnings’ section at the
beginning of this user manual, as well as other warnings and notes throughout the manual.
Electrical Supplies
The unit requires a 3-phase balanced Mains Supply to provide the power for the controlled motor, and a 24Vdc
for the internal control circuitry. The unit will not operate unless the control supply voltage is within the specified
limits.

The EGS Series provides full motor overload protection, configurable through the user interface. Overload trip
settings are determined by the Motor Current setting and the Trip Class setting. Trip class choices are Class 10,
Class 20, and Class 30. The EGS Series soft starters are protected using full I2T motor overload with memory.
Please note: When the overload has tripped, there is a forced cooling time to allow the overload to recover
before the next start.
The ‘warm’ trip times are 50% of the ‘cold’ trip time
