Warnings
Isolation
Caution: agility
TM
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 agility
TM
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
agility
TM
