Safety Instructions and General Warnings

MCO 305

Operating Instructions

Software version: 4.xx

These Operating Instructions can be used for the MCO 305 option board

with all FC 300 frequency converters with software version 4.0x.

The software version number can be seen from parameter 15-43.



High Voltage Warning

The voltage of the FC 300 is dangerous whenever the converter is connected to mains.

Incorrect fitting of the motor or FC 300 may cause damage to the equipment, serious injury or death.

Consequently, it is essential to comply with the instructions in this manual as well as local and national rules

and safety regulations.

At altitudes above 2 km, please contact Danfoss Drives regarding PELV.



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 par. 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.



Before Commencing Repair Work

1. Disconnect FC 300 from mains.

2. Disconnect DC bus terminals 88 and 89.

3. Wait at least 4 minutes.

4. Remove motor plugs.



Avoid Unintended Start

While FC 300 is connected to mains, the motor can be started/stopped using digital commands, bus

commands, references or via the LCP.

Disconnect the FC 300 from mains whenever personal safety considerations make it necessary to avoid

unintended start.

To avoid unintended start, always activate the [OFF] key before changing parameters.

Unless terminal 37 is turned off, an electronic fault, temporary overload, a fault in the mains supply, or

lost motor connection may cause a stopped motor to start.



Safe Stop of FC 302

The FC 302 can perform the Designated Safety Function Uncontrolled Stopping by removal of power (as

defined by draft IEC 61800-5-2) or Stop Category 0 (as defined in EN 60204-1). It is designed and appro-

ved suitable for the requirements of Safety Category 3 in EN 954-1. This functionality is called Safe Stop.

In order to install and use the Safe Stop function in accordance with the requirements of Safety Category 3

in EN 954-1, the related information and instructions of the FC 300 Design Guide MG.33.BX.YY must be

followed! The information and instructions of the Operating Instructions are not sufficient for a correct and

safe use of the Safe Stop functionality!



General Warning

Warning:

Touching the electrical parts may be fatal – even after the

equipment has been disconnected from mains.

Also make sure that all voltage inputs have been disconnected,

such as load-sharing (linkage of DC intermediate circuit), as well

as the motor connection for kinetic back-up.

Using VLT AutomationDrive FC 300 (at and below 7.5 kW):

wait at least xx minutes.

xx = The waiting time using the VLT AutomationDrive FC 300 is

different for different sizes: Please see period of waiting time xx in

the FC 300 Operating Instructions.



How to Get Started

Please consult the FC 300 Operating Instructions (MG.AX-XX) for correct installation of FC 300, this

instruction covers installation of MCO 305.

The installation procedure depends on whether the MCO 305 was delivered as an option for upgrading an

existing FC 300 or if it was preinstalled before delivery. Skip the next chapter (Mechanical installation) if the

MCO 305 was preinstalled:



Initialize the frequency converter to default setting in two ways:

Recommended initialization (via par. 14-22):

1. Select par. 14-22

2. Press [OK]

3. Select “Initialization”

4. Press [OK]

5. Cut off the mains supply and wait until the

displays turns off.

6. Reconnect the mains supply – the frequency

converter is now reset.

NB!

MCO 305 programs and arrays are not

affected.

Par. 14-22 initializes all except:

14-50 RFI 1

8-30 Protocol

8-31 Address

8-32 Baud Rate

8-35 Minimum Response Delay

8-36 Maximum Response Delay

8-37 Max Inter-char Delay

Manual initialization

1. Disconnect from mains and wait until the

display turns off.

2. Press [Status] – [Main Menu] – [OK] at the

same time:

3. Reconnect mains supply while pressing the keys.

4. Release the keys after 5 s.

5. The frequency converter is now programmed

according to default settings.

This method initializes all except:

15-00 Operating Hours

15-03 Power-up’s

15-04 Over temp’s

15-05 Over volt’s

NB!:

When you carry out manual initialization, you also reset serial communication and fault log

settings.

And all MCO 305 programs and arrays are deleted!
