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:

380 - 480 V: At altitudes above 3 km, please contact Danfoss Drives regarding PELV.

525 - 690 V: At altitudes above 2 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.

Instruction Manual 2 Safety

MG.20.U1.22

2.1.2 General Warning

Leakage Current

The earth leakage current from the Automation VT Drive FC322 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 Automation VT Drive FC322 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 Automation VT 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 Automation VT 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:

525-690 11 - 90 kW 45 - 400 kW 450 - 1200 kW

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

2.1.6 Avoid Un-intended Start

NB!

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 IT Mains

IT mains

Do not connect frequency converters with RFI-filters to mains supplies with a voltage between phase and earth of more than 440 V

for 400 V converters and 760 V for 690 V converters.

For 400 V IT mains and delta earth (grounded leg), mains voltage may exceed 440 V between phase and earth.

For 690 V IT mains and delta earth (grounded leg), mains voltage may exceed 760 V between phase and earth.

Par. 14-50

RFI Filter

can be used to disconnect the internal RFI capacitors from the RFI filter to ground.

2.1.8 Disposal Instruction

Equipment containing electrical components must not be disposed of together with domestic waste.

It must be separately collected with electrical and electronic waste according to local and currently valid leg-

islation.

2.1.9 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

Automation VT Drive FC322

Instruction Manual 2 Safety

MG.20.U1.22

Category 3 in EN 954-1, the related information and instructions of the Automation VT Drive Design Guide MG.20.X1.22 must be followed! The information

and instructions of the Instruction Manual are not sufficient for a correct and safe use of the Safe Stop functionality!
