If Hand On mode is selected on the frequency converter control panel, the motor can be run from the panel.
Even in this case, the locking must be disabled (connectors 12 and 27 connected). To enable bus control or con -
trol connectors, activate Auto On mode from the control panel.
Control cables between the building automation system and frequency converter must be screened, and the
screen is connected on the frequency converter end only. If the motor cable has to be replaced with a longer
one, the connection must be made according to the general EMC requirements. The length of the motor cable
must not exceed 10 meters.
The frequency converter supply cable must be equipped with a service switch. If necessary, the service switch
can also be installed on the motor cable, in which case the service switch must be EMC approved. Connections
must be made according to the EMC requirements.
The frequency converter takes care of the motor output’s short circuit and leakage protection and frequency
converter overload protection. However, the frequency converter must be protected against a short circuit with,
for example, fuses. In addition, installations (like cables, etc.) upstream of the frequency converter must also be
provided with overload protection. The protective earthing of the frequency converter must comply with both
the above-mentioned and national requirements.
The rotation direction of PM motors equipped with separate frequency converters must be checked before final
commissioning. If the rotation direction is incorrect, it can be reversed by interchanging the two motor cable
