MCO 350 Synchronising Controller for

VLT AutomationDrive FC 30x

Operating Instructions

Software version: 1.1x

 

 

 

 

 

 

These Operating Instructions can be used for all MCO 350 Synchronising Controller for VLT
AutomationDrive FC 30x

 

 frequency converters with software version 1.1x.

The software version number can be seen from parameter 19-92.

1.1.4. High Voltage 

The voltage of the frequency converter is dangerous whenever the frequency con-
verter is connected to mains. Incorrect installation or operation of the motor or
frequency converter may cause damage to the equipment, serious personal injury
or death. The instructions in this manual must consequently be observed, as well as
applicable local and national rules and safety regulations.

Installation in high altitudes

380 - 500 V: At altitudes above 3 km, please contact Danfoss Drives regarding PELV.
525 - 690 V: At altitudes above 2 km, please contact Danfoss Drives regarding PELV.

1.1.5. Safety Instructions 

•

Make sure the FC 300 is properly connected to earth.

•

Do not remove mains plugs or motor plugs while the FC 300 is connected to mains.

•

Protect users against supply voltage.

•

Protect the motor against overloading according to national and local regulations.

•

Motor overload protection is not included in the default settings. To add this function,
set parameter 1-90 

Motor thermal protection

 to value 

ETR trip

 or 

ETR warning

. For the

North American market: ETR functions provide class 20 motor overload protection, in
accordance with NEC.

•

The earth leakage current exceeds 3.5 mA.

•

The [OFF] key is not a safety switch. It does not disconnect the FC 300 from mains.
