EGS Series Quick Start User Manual
Version 01 - 2020
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.
