In order to drive the motor again, it is required to apply STO1 and STO2 signals again (to close terminals 13
to 23 and 23 to 24) and apply a pulse on inverter DI1 input (START).

3.4 INSTALLATION ACCORDING TO THE EUROPEAN DIRECTIVE OF ELECTROMAGNETIC
COMPATIBILITY
The CFW-11 inverters with frame sizes F, G and H feature internal RFI filter to reduce the electromagnetic
interference.
These inverters, when properly installed, meet the requirements of the electromagnetic compatibility directive
‘’EMC Directive 2014/30/EU’’.
The CFW-11 inverter series has been designed only for industrial applications. Therefore, the emission limits
of harmonic currents defined by the standards EN 61000-3-2 and EN 61000-3-2/A14 are not applicable.
ATTENTION!
For using models with internal RFI filters in IT networks follow the instructions on Item 3.2.3.1.2 IT
Networks on page 3-22.
3.4.1 Conformal Installation
For the conformal installation use:
1. Shielded output cables (motor cables) with the shield connected at both ends, motor and inverter, by means
of a low impedance to high frequencies connection.
Use the clamps supplied with the product, making sure there is a good contact between the shield and that
clamp.
