2 Safety and Conformity
2.1 Safety Precautions
2.1.1 Safety Precautions
The voltage of the frequency converter is dangerous whenever connected to mains. Incorrect installation of the motor, frequency
converter or fieldbus may cause death, serious personal injury or damage to the equipment. Consequently, the instructions in this
manual, as well as national and local rules and safety regulations, must be complied with.
Safety Regulations
1. The mains supply to the frequency converter must be disconnected whenever repair work is to be carried out. Check that the mains supply has
been disconnected and that the necessary time has elapsed before removing motor and mains supply plugs.
2. The [OFF] button on the control panel of the frequency converterr does not disconnect the mains supply and consequently it must not be used
as a safety switch.
3. The equipment must be properly earthed, 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 current exceeds 3.5 mA.
5. Protection against motor overload is not included in the factory setting. If this function is desired, set par. 1-90
Motor Thermal Protection
to
data value ETR trip 1 [4] or data value ETR warning 1 [3].
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 elapsed before removing motor and mains plugs.
7. Please note that the frequency converter has more voltage sources than L1, L2 and L3, when load sharing (linking of DC intermediate circuit)
or external 24 V DC are installed. Check that all voltage sources have been disconnected and that the necessary time has elapsed before
commencing repair work.
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 (e.g. risk of personal injury caused by contact with moving machine parts following an
unintentional start) make it necessary to ensure that no unintended start occurs, these stop functions are not sufficient. In such cases the mains
supply must be disconnected or the
Safe Stop
function must be activated.
2. The motor may start while setting the parameters. If this means that personal safety may be compromised (e.g. personal injury caused by
contact with moving machine parts), motor starting must be prevented, for instance by use of the
Safe Stop
function or secure disconnection
of the motor connection.
3. A motor that has been stopped with the mains supply connected, may start if faults occur in the electronics of the frequency converter, through
temporary overload or if a fault in the power supply grid or motor connection is remedied. If unintended start must be prevented for personal
safety reasons (e.g. risk of injury caused by contact with moving machine parts), the normal stop functions of the frequency converter are not
sufficient. In such cases the mains supply must be disconnected or the
Safe Stop
function must be activated.
NB!
When using the
Safe Stop
function, always follow the instructions in the
Safe Stop
section of the VLT AutomationDrive Design Guide.
4. Control signals from, or internally within, the frequency converter may in rare cases be activated in error, be delayed or fail to occur entirely.
When used in situations where safety is critical, e.g. when controlling the electromagnetic brake function of a hoist application, these control
signals must not be relied on exclusively.

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.
Systems where frequency converters are installed must, if necessary, be equipped with additional monitoring and protective devices
according to the valid safety regulations, e.g law on mechanical tools, regulations for the prevention of accidents etc. Modifications on
the frequency converters by means of the operating software are allowed.
NB!
Hazardous situations shall be identified by the machine builder/ integrator who is responsible for taking necessary preventive means
into consideration. Additional monitoring and protective devices may be included, always according to valid national safety regulations,
e.g. law on mechanical tools, regulations for the prevention of accidents.
NB!
Crane, Lifts and Hoists:
The controlling of external brakes must always have a redundant system. The frequency converter can in no circumstances be the
primary safety circuit. Comply with relevant standards, e.g.
Hoists and cranes: IEC 60204-32
Lifts: EN 81
Protection Mode
Once a hardware limit on motor current or dc-link voltage is exceeded the frequency converter will enter “Protection mode”. “Protection mode” means a
change of the PWM modulation strategy and a low switching frequency to minimize losses. This continues 10 sec after the last fault and increases the
reliability and the robustness of the frequency converter while re-establishing full control of the motor.
In hoist applications “Protection mode” is not usable because the frequency converter will usually not be able to leave this mode again and therefore it
will extend the time before activating the brake – which is not recommendable.
The “Protection mode” can be disabled by setting par. 14-26
Trip Delay at Inverter Fault
to zero which means that the frequency converter will trip
immediately if one of the hardware limits is exceeded.
NB!
It is recommended to disable protection mode in hoisting applications (par. 14-26
Trip Delay at Inverter Fault
= 0)
The DC link capacitors remain charged after power has been disconnected. To avoid electrical shock hazard, disconnect the frequency
converter from mains before carrying out maintenance. When using a PM-motor, make sure it is disconnected. Before doing service
on the frequency converter wait at least the amount of time indicated below:
Voltage Power Waiting Time
380 - 500 V 0.25 - 7.5 kW 4 minutes
11 - 75 kW 15 minutes
90 - 200 kW 20 minutes
250 - 800 kW 40 minutes
525 - 690 V 11-75 kW (frame size B and C) 15 minutes
37 - 315 kW (frame size D) 20 minutes
355 - 1000 kW 30 minutes

3 Introduction to Extended Relay Card MCB 113
The VLT Extended Relay Card MCB 113 is constructed as a standard C1 option for the Danfoss VLT AutomationDrive FC 300 and is automatically detected
after mounting.
The MCB 113 adds 7 digital inputs, 2 analog outputs and 4 SPDT relays to the standard I/O of the frequency converter which makes it possible to comply
with the German NAMUR NE37 recommendations.
