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

By altitudes above 2 km, please contact Danfoss 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 [STOP/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.

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 VLT AQUA Drive FC 200, wait at least as follows:

200 - 240 V, 0.25 - 3.7 kW: wait at least 4 minutes.

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

380 - 480 V, 0.37 - 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.

525 - 600 V, 110 - 250 kW, wait at least 20 minutes.

525 - 600 V, 315 - 560 kW, wait at least 30 minutes.

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

Leakage Current

The earth leakage current from the VLT AQUA Drive FC 200 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 VLT AQUA Drive FC 200 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 2.1.2

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, whichaffect 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. Caution

The frequency converter DC link capacitors remain charged after power has been disconnected. 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 frequency converter:

Voltage Min. Waiting Time

4 min. 15 min. 20 min. 30 min.

200 - 240 V 0.25 - 3.7 kW 5.5 - 45 kW

380 - 480 V 0.37 - 7.5 kW 11 - 90 kW 110 - 250 kW 315 - 450 kW

525-600 V 0.75 kW - 7.5 kW 110 - 250 kW 315 - 560 kW

525-690 V 45 - 400 kW 450 - 630 kW

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

2.1.6. 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.

2.1.7. Safe Stop of the Frequency Converter (optional)

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!
