2 Safety

2.1.1 Safety note

The voltage of the frequency converter is dangerous whenever connected to mains. Incorrect installation of the motor, frequency

converter or fieldbus may cause damage to the equipment, serious personal injury or death. Consequently, the instructions in this

manual, as well as national and local rules and safety regulations, must be complied with.

Safety Regulations

1. The frequency converter must be disconnected from mains if repair work is to be carried out. Check that the mains supply has been disconnected

and that the necessary time has passed before removing motor and mains plugs.

2. The [STOP/RESET] key on the control panel of the frequency converter does not disconnect the equipment from mains and is thus not to be

used as a safety switch.

3. Correct protective earthing of the equipment must be established, the user must be protected against supply voltage, and the motor must be

protected against overload in accordance with applicable national and local regulations.

4. The earth leakage currents are higher than 3.5 mA.

5. Protection against motor overload is set by par. 1-90

Motor Thermal Protection

. If this function is desired, set par. 1-90 to data value [ETR trip]

(default value) or data value [ETR warning]. Note: The function is initialised at 1.16 x rated motor current and rated motor frequency. For the

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

6. Do not remove the plugs for the motor and mains supply while the frequency converter is connected to mains. Check that the mains supply has

been disconnected and that the necessary time has passed before removing motor and mains plugs.

7. Please note that the frequency converter has voltage inputs other than L1, L2 and L3, when load sharing (linking of DC intermediate circuit) and

external 24 V DC have been installed. Check that all voltage inputs have been disconnected and that the necessary time has passed before

commencing repair work.

Installation at High Altitudes

Installation at high altitude:

At altitudes above 3 km, please contact Danfoss Drives regarding PELV

Warning against Unintended Start

1. The motor can be brought to a stop by means of digital commands, bus commands, references or a local stop, while the frequency converter is

connected to mains. If personal safety considerations make it necessary to ensure that no unintended start occurs, these stop functions are not sufficient.

2. While parameters are being changed, the motor may start. Consequently, the stop key [RESET] must always be activated; following which data can

be modified. 3. A motor that has been stopped may start if faults occur in the electronics of the frequency converter, or if a temporary overload or a fault

in the supply mains or the motor connection ceases.

Warning:

Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains.

Also make sure that other voltage inputs have been disconnected, such as external 24 V DC, load sharing (linkage of DC intermediate circuit), as well as

the motor connection for kinetic back up.

MG.20.T1.02 - VLT® is a registered Danfoss trademark 7

2.1.2 General Warning

Warning:

Touching the electrical parts may be fatal - even after the equipment has been disconnected 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 frequency converter, wait at least as follows:

380 - 480 V, 160 - 250 kW, wait at least 20 minutes.

380 - 480 V, 315- 710 kW, wait at least 40 minutes.

Shorter time is allowed only if indicated on the nameplate for the specific unit. Be aware that there may be high voltage on the DC

links even when the Control Card LEDs are turned off. A red LED is mounted on a circuit board inside both the drive and the active

filter to indicate the DC bus voltages. The red LED will stay lit until the DC link is 50 Vdc or lower.

Leakage Current

The earth leakage current from the frequency converter exceeds 3.5 mA. According 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 delayed) shall be used on the supply side of this product. See also RCD Application Note MN.90.GX.02.

Protective earthing of the frequency converter and the use of RCD's must always follow national and local regulations.

2.1.3 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 General Warning above

4. Remove motor cable

2.1.4 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 expected 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 derating of the electrical ratings

• Marine applications with more severe environmental conditions.

Consult the relevant clauses in these instructions and in the VLT® AQUA 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® AQUA Drive Design Guide for information about the installation requirements.

2.1.5 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 unin-

tended 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.

2.1.6 Safe Stop Installation

To carry out an installation of a Category 0 Stop (EN60204) in

conformity with Safety Category 3 (EN954-1), follow these in-

structions:

1. The bridge (jumper) between Terminal 37 and 24 V DC must be

removed. Cutting or breaking the jumper is not sufficient. Re-

move it entirely to avoid short-circuiting. See jumper on illus-

tration.

2. Connect terminal 37 to 24 V DC by a short-circuit protected ca-

ble. The 24 V DC voltage supply must be interruptible by an

EN954-1 Category 3 circuit interrupt device. If the interrupt de-

vice and the frequency converter are placed in the same instal-

lation panel, you can use an unscreened cable instead of a

screened one. Illustration 2.1: Bridge jumper between terminal 37 and 24

VDC

The illustration below shows a Stopping Category 0 (EN 60204-1) with safety Category 3 (EN 954-1). The circuit interrupt is caused by an opening door

contact. The illustration also shows how to connect a non-safety related hardware coast.

Illustration 2.2: Illustration of the essential aspects of an installation to achieve a Stopping Category 0 (EN 60204-1) with safety Category

3 (EN 954-1).

2.1.7 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 AQUA Drive Design Guide MG.20.NX.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!
