Switching a motor holding brake is inadmissible
Do not use a motor brake in parallel with the connected motor. This applies both to
connection between phases and to connection to the neutral conductor.
Checking the settings
Always check the safety-related parameters during acceptance of the system. Also always
check the parameters if a parameter has been changed or if you are commissioning the
system for the first time.
Operation by experienced users only
Use the fail-safe motor starter only if you are familiar with motors and safety-related
applications.
ATEX certified motor overload protection
ET 200SP fail-safe motor starters are approved under device group II, Category (2) in the
"GD" area. This means that the fail-safe motor starters can protect motors that are located in
hazardous gas, vapor, mist and air mixtures and also combustible dust. The motor starter
itself must not be situated in the hazardous area.
Due to the increased danger in hazardous areas, observe the following standards:
● EN 60079-14 / VDE 0165-1 Explosive atmospheres - Part 14: Electrical installations
● EN 60079-17 Explosive atmospheres - Part 17: Electrical installations inspection and
maintenance
● EN 50495 Safety devices required for the safe functioning of equipment with respect to
explosion risks
