1.1.1 Symbols
Symbols used in this manual:
NOTE!
Indicates something to be noted by the reader.
Indicates a general warning.
Indicates a high-voltage warning.
✮Indicates a default setting
1.1.2 High voltage warning
The voltage of the adjustable frequency drive and the MCO 101 option card is dangerous whenever it is connected to line power.
Incorrect installation of the motor or adjustable frequency drive may cause damage to the equipment, serious injury or death. Con-
sequently, it is essential to comply with the instructions in this manual as well as local and national rules and safety regulations.
1.1.3 Safety instructions
Prior to using functions directly or indirectly influencing personal safety (e.g., Safe Stop, Fire Mode or other functions either forcing
the motor to stop or attempting to keep it functioning), a thorough risk analysis and system test must be carried out. The system
tests must include testing failure modes regarding the control signaling (analog and digital signals and serial communication.
NOTE!
Before using fire mode, contact Danfoss

• Make sure the adjustable frequency drive is properly grounded.
• Do not remove AC line input connections, motor connections or other power connections while the adjustable frequency drive is connected to
line power.
• Protect users against supply voltage.
• Protect the motor against overloading in accordance with national and local regulations.
• The ground leakage current exceeds 3.5 mA.
• The [OFF] key is not a safety switch. It does not disconnect the adjustable frequency drive from line power.
1.1.4 Before Commencing Repair Work
1. Disconnect the adjustable frequency drive from line power.
2. Disconnect DC bus terminals 88 and 89.
3. Wait at least the time mentioned above in the section General Warning.
4. Remove motor cable
1.1.5 Special conditions
Electrical ratings:
The rating indicated on the nameplate of the adjustable frequency drive is based on a typical 3-phase line power supply within the specified voltage,
current and temperature ranges, which are expected to be used in most applications.
The adjustable frequency drives also support other special applications, which affect the electrical ratings of the adjustable frequency drive.
Special conditions that affect the electrical ratings might be:
• Single phase applications.
• High temperature applications that require derating of the electrical ratings.
• Marine applications with more severe environmental conditions.
Other applications might also affect the electrical ratings.
Consult the relevant sections in this manual and in the
VLT HVAC Drive Design Guide, MG.11.BX.YY for information about the electrical ratings.
Installation requirements:
The overall electrical safety of the adjustable frequency drive requires special installation considerations regarding:
• Fuses and circuit breakers for overcurrent and short-circuit protection
• Selection of power cables (line power, motor, brake, load sharing and relay)
• Grid configuration (IT,TN, grounded leg, etc.)
• Safety of low-voltage ports (PELV conditions).
Consult the relevant clauses in these instructions and in the
VLT HVAC Drive Design Guide for information about the installation requirements.

1.1.6 Caution
Caution
The adjustable frequency drive DC link capacitors remain charged after power has been disconnected. To avoid an electrical shock hazard, disconnect
the adjustable frequency drive from line power before carrying out maintenance. Wait at least as follows before doing service on the adjustable
frequency drive:
Voltage Minimum Waiting Time
4 min. 15 min. 20 min. 30 min. 40 min.
200–240 V 1.1 - 3.7 kW 7.5–60 hp [5.5–45 kW]
380–480 V 1.1 - 7.5 kW 15–125 hp [11–90 kW] 150–300 hp [110–200
kW] 350–600 hp [250–450 kW]
525–600 V 1.5–10 hp [1.1–7.5
kW] 150–350 hp [110–250 kW]
450–750 hp [315–560
kW]
525–690 V 60–125 hp [45–90 kW] 150–350 hp [110– 250
kW]
450–750 hp [315– 560
kW]
850–1600 hp [630–
1200 kW]
Be aware that there may be high voltage on the DC link even when the LEDs are turned off.
1.1.7 Installation at high altitudes (PELV)
At altitudes above 6,600 feet [2 km], please contact Danfoss regarding PELV.
1.1.8 Avoid unintended Start.
While the adjustable frequency drive is connected to line power, the motor can be started/stopped using digital commands, bus
commands, references or via the Local Control Panel.
• Disconnect the adjustable frequency drive from line power whenever personal safety considerations make it necessary to avoid an unintended
start.
• To avoid an 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 line power supply or lost motor connection may cause a
stopped motor to start.
1.1.9 Safe Stop of the Adjustable Frequency Drive
For versions equipped with a Safe Stop terminal 37 input, the adjustable frequency drive can perform the safety function Safe Torque Off (as defined by
draft CD IEC 61800-5-2) or
Stop Category 0 (as defined in EN 60204-1).
It is designed and deemed suitable for the requirements of Safety Category 3 in EN 954-1. This functionality is called Safe Stop. Prior to integrating and
using safe stop in an installation, a thorough risk analysis must be carried out on the installation in order to determine whether the safe stop functionality
and safety category are appropriate and sufficient. 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
VLT HVAC Drive Design Guide must be followed! The information and instructions contained
in the Instruction Manual are not sufficient for a correct and safe use of the safe stop functionality!

1.1.10 IT Line Power
IT Line Power
Do not connect 400 V adjustable frequency drives with RFI filters to line supplies with a voltage between phase and ground of more
than 440 V.
For IT line power and delta ground (grounded leg), AC line voltage may exceed 440 V between phase and ground.
par. 14-50 RFI 1 can be used to disconnect the internal RFI capacitors from the RFI filter to ground. If this is done, it will reduce the RFI performance
to A2 level.
1.1.11 Software version and approvals: VLT HVAC Drive
VLT HVAC Drive
Software version: 3.1.x
This manual can be used with all VLT HVAC Drive adjustable frequency drives with software version 3.1.x.
