1. Safety

1.1.1. Symbols

Symbols used in this Operating Instructions.

NB!

Indicates something to be noted by the reader.

Indicates a general warning.

Indicates a high-voltage warning.

* Indicates default setting

1.1.2. High Voltage Warning

The voltage of the frequency converter is dangerous whenever it is connected to

mains. Incorrect installation of the motor or frequency converter 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.

Installation at high altitudes:

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

1.1.3. Safety Instructions

• Make sure the frequency converter is properly connected to earth.

• Do not remove mains connections, motor connections or other power connections while

the frequency converter is connected to mains.

• Protect users against supply voltage.

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

• Motor overload protection is included in the default settings. Parameter 1-90

Motor ther-

mal protection

is set to value

ETR trip.

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 frequency converter from

mains.

1.1.4. General Warning

Warning:

Touching the electrical parts may be fatal - even after the equipment has been dis-

connected from mains.

Also make sure that other voltage inputs have been disconnected, (linkage of DC

intermediate circuit), as well as the motor connection for kinetic back-up.

Before touching any potentially live parts of the VLT

HVAC Drive FC 100, wait at

least as follows:

200 - 240 V, 1.1 - 3.7 kW: wait at least 4 minutes.

200 - 240 V, 5.5 - 45 kW: wait at least 15 minutes.

380 - 480 V, 1.1 - 7.5 kW: wait at least 4 minutes.

380 - 480 V, 11 - 90 kW, wait at least 15 minutes.

525 - 600 V, 1.1 - 7.5 kW, wait at least 4 minutes.

Shorter time is allowed only if indicated on the nameplate for the specific unit.

Leakage Current

The earth leakage current from the VLT

HVAC Drive FC 100 exceeds 3.5 mA. Ac-

cording to IEC 61800-5-1 a reinforced Protective Earth connection must be ensured

by means of: a min. 10mm² Cu or 16mm² Al PE-wire or an addtional PE wire - with

the same cable cross section as the Mains wiring - must be terminated separately.

Residual Current Device

This product can cause a D.C. current in the protective conductor. Where a residual

current device (RCD) is used for extra protection, only an RCD of Type B (time de-

layed) shall be used on the supply side of this product. See also RCD Application

Note MN.90.GX.02.

Protective earthing of the VLT

HVAC Drive FC 100 and the use of RCD's must always

follow national and local regulations.

1.1.5. Before Commencing Repair Work

1. Disconnect the frequency converter from mains

2. Disconnect DC bus terminals 88 and 89

3. Wait at least the time mentioned in section 1.1.6

4. Remove motor cable

1.1.6. Special conditions

Electrical ratings:

The rating indicated on the nameplate of the frequency converter is based on a typical 3-phase

mains power supply, within the specified voltage, current and temperature range, which is ex-

pected to be used in most applications.

The frequency converters also support other special applications, which affect the electrical ratings

of the frequency converter.

Special conditions which affect the electrical ratings might be:

Single phase applications

High temperature applications which require de-rating of the electrical ratings

Marine applications with more severe environmental conditions.

Other applications might also affect the electrical ratings.

1. Safety VLT

HVAC Drive Operating Instructions

MG.11.A4.02 - 09.10.06. VLT®is a registered Danfoss trademark

Consult the relevant clauses in these instructions and in the

VLT® HVAC Drive Design Guide

for

information about the electrical ratings.

Installation requirements:

The overall electrical safety of the frequency converter requires special installation considerations

regarding:

Fuses and circuit breakers for over-current and short-circuit protection

Selection of power cables (mains, motor, brake, loadsharing 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.

1.1.7. Caution

Caution

The frequency converter DC link capacitors remain charged after power has been disconnec-

ted. To avoid an electrical shock hazard, disconnect the frequency converter from the mains

before carrying out maintenance. Wait at least as follows before doing service on the fre-

quency converter:

Voltage Min. Waiting Time

4 min. 15 min.

200 - 240 V

1.1 - 3.7 kW 5.5 - 45 kW

380 - 480 V 1.1 - 7.5 kW 11 - 90 kW

525 - 600 V 1.1 - 7.5 kW

Be aware that there may be high voltage on the DC link even when the LEDs are turned off.

1.1.8. Installation at High Altitudes (PELV)

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

1.1.9. Avoid unintended Start

While the frequency converter is connected to mains, the motor can be started/stopped using

digital commands, bus commands, references or via the Local Control Panel.

• Disconnect the frequency converter 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.

1.1.10. Safe Stop of the Frequency Converter

For versions fitted with a Safe Stop terminal 37 input, the frequency converter 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 approved suitable for the requirements of Safety Category 3 in EN 954-1. This

functionality is called Safe Stop. Prior to integration and use of Safe Stop in an installation, a

thorough risk analysis on the installation must be carried out 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 MG.11.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!

1.1.11. IT Mains

IT Mains

Do not connect 400 V frequency converters with RFI-filters to mains supplies with a

voltage between phase and earth of more than 440 V.

For IT mains and delta earth (grounded leg), mains voltage may exceed 440 V be-

tween phase and earth.

Par. 14-50

RFI 1

can be used to disconnect the internal RFI capacitiors from the RFI filter to

ground. If this is done it will reduce the RFI performance to A2 level.
