VLT®is a registered trademark for Danfoss A/S.
1.2 Additional Resources
1.2.1 Other Resources
Other resources are available to understand advanced drive functions and programming.
VLT® Flow Drive FC 111 Operating Guide provides basic information on mechanical dimensions, installation, and programming.
VLT® Flow Drive FC 111 Design Guide provides information on how to design motor control systems.
Danfoss VLT® Energy Box software. Select PC Software Download at www.danfoss.com.
VLT® Energy Box software allows energy consumption comparisons of HVAC fans and pumps driven by Danfoss drives and alterna-
tive methods of flow control. Use this tool to accurately project the costs, savings, and payback of using Danfoss drives on HVAC
fans, pumps, and cooling towers.
Supplementary publications and manuals are available from Danfoss website.
1.2.2 MCT 10 Set-up Software Support
Download the software from the service and support section on www.danfoss.com.
During the installation process of the software, enter access code 81462700 to activate the VLT® Flow Drive FC 111 functionality. A
license key is not required for using the VLT® Flow Drive FC 111 functionality.
The latest software does not always contain the latest updates for drives. Contact the local sales office for the latest drive updates (in
the form of *.OSS files).
1.3 Document and Software Version
This guide is regularly reviewed and updated. All suggestions for improvement are welcome.

2 Safety
2.1 Safety Symbols
The following symbols are used in this manual:
DANGER
Indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION
Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
NOTICE
Indicates information considered important, but not hazard-related (for example, messages relating to property damage).
2.2 Qualified Personnel
To allow trouble-free and safe operation of the unit, only qualified personnel with proven skills are allowed to transport, store, as-
semble, install, program, commission, maintain, and decommission this equipment.
Persons with proven skills:
Are qualified electrical engineers, or persons who have received training from qualified electrical engineers and are suitably
experienced to operate devices, systems, plant, and machinery in accordance with pertinent laws and regulations.
Are familiar with the basic regulations concerning health and safety/accident prevention.
Have read and understood the safety guidelines given in all manuals provided with the unit, especially the instructions given in
the Operating Guide.
Have good knowledge of the generic and specialist standards applicable to the specific application.
2.3 Safety Precautions
WARNING
HAZARDOUS VOLTAGE
AC drives contain hazardous voltage when connected to the AC mains or connected on the DC terminals. Failure to perform
installation, start-up, and maintenance by skilled personnel can result in death or serious injury.
Only skilled personnel must perform installation, start-up, and maintenance.
WARNING
UNINTENDED START
When the drive is connected to AC mains, DC supply, or load sharing, the motor may start at any time. Unintended start during
programming, service, or repair work can result in death, serious injury, or property damage. Start the motor with an external
switch, a fieldbus command, an input reference signal from the local control panel (LCP), via remote operation using MCT 10
software, or after a cleared fault condition.
Disconnect the drive from the mains.
Press [Off/Reset] on the LCP before programming parameters.
Ensure that the drive is fully wired and assembled when it is connected to AC mains, DC supply, or load sharing.

WARNING
DISCHARGE TIME
The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be
present even when the warning indicator lights are off.
Failure to wait the specified time after power has been removed before performing service or repair work could result in death or
serious injury.
Stop the motor.
Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and
DC-link connections to other drives.
Wait for the capacitors to discharge fully. The minimum waiting time is specified in the table Discharge time and is also visible
on the nameplate on the top of the drive.
Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors
are fully discharged.

WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the drive properly can result in death or serious injury.
Ensure that the minimum size of the ground conductor complies with the local safety regulations for high touch current
equipment.
WARNING
EQUIPMENT HAZARD
Contact with rotating shafts and electrical equipment can result in death or serious injury.
Ensure that only trained and qualified personnel perform installation, start-up, and maintenance.
Ensure that electrical work conforms to national and local electrical codes.
Follow the procedures in this manual.
CAUTION
INTERNAL FAILURE HAZARD
An internal failure in the drive can result in serious injury when the drive is not properly closed.
Ensure that all safety covers are in place and securely fastened before applying power.

The LCD-display of LCP 32 is illuminated with 3 alphanumeric lines, while the LCD-display of LCP 31 is illuminated with 2 alphanu-
meric lines. All data is shown on the LCP. The Table 3 describes the information that can be read from the display.

The setup number shows the active setup and the edit setup.
For LCP 32, the setup number only shows in Status menu, the number outside brackets is active setup, and the number inside
brackets is edit setup. For example, 1(2) means 1 is the active setup, and 2 is the edit setup.
For LCP 31, if the same setup acts as both active and edit setup, only that setup number is shown (factory setting). When the
active and the edit setup differ, both numbers are shown in the display (setup 12). The number flashing indicates the edit
setup.
