High Voltage Warning
WARNING
The voltage of the frequency converter and the MCO 101 option card is dangerous whenever it is connected to mains.
Incorrect installation of the motor or frequency converter could result indeath, serious injury or damage to the equip-
ment. Consequently, it is essential to comply with the instructions in this manual as well as local and national rules and
safety regulations.
Safety Note
WARNING
The voltage of the frequency converter is dangerous whenever connected to mains. Incorrect installation of the motor,
frequency converter or fieldbus could result in death, serious personal injury or damage to the equipment. Conse-
quently, the instructions in this manual, as well as national and local rules and safety regulations, must be complied
with.
WARNING
Failure to follow instructions below could result in death or serious injury.
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 keypad 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 Motor Thermal Protection to data value [ETR trip] (default value) or data value [ETR warning].
Note: The function is initialized 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 more voltage inputs than L1, L2 and L3, when load sharing
(linking of DC intermediate circuit) and external 24 Vdc have been installed. Check that all voltage inputs
have been disconnected and that the necessary time has passed before commencing repair work.
Safety
TR200 Programming Guide 5

Installation at high altitudes
WARNING
Installation at high altitude:
380 - 500 V, enclosure A, B and C: At altitudes above 2 km (6,561 ft), please contact Trane regarding PELV/Class II.
380 - 500 V, enclosure D, E and F: At altitudes above 3 km (9,842 ft), please contact Trane regarding PELV/Class II.
If the drive is to be installed over 2000m (6,561 ft) altitude, then the PELV specifications are not fulfilled anymore, i.e.
the distances between components and critical parts become too small. To keep anyway the clearance for functional
insulation, the risk for over-voltage must be reduced by means of external protective devices or kind of galvanic isolation.
De-rating should also be taken into consideration, as cooling of the drive is not so effective at high altitude. Please
contact Trane in such cases.
Failure to follow recommendations could result in death or serious injury.
WARNING
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.
Consequently, disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be inadvertently energized. Failure to follow recommendations could
result in death or serious injury.
WARNING
Touching the electrical parts could result in death or serious injury - even after the equipment has been disconnected
from mains.
Also make sure that other voltage inputs have been disconnected, such as external 24 Vdc, load sharing (linkage
of DC intermediate circuit), as well as the motor connection for kinetic back up. Refer to the Operating Instruc-
tions for further safety guidelines.
Failure to follow recommendations could result in death or serious injury.
WARNING
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:
Failure to follow recommendations could result in death or serious injury.

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 ap-
plications.
The frequency converters also support other special applications, which affect the electrical ratings of the fre-
quency 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.
Consult the relevant sections in this manual and in the 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 (grounded delta transformer leg, IT,TN, etc.)
• Safety of low-voltage ports (PELV conditions).
Consult the relevant clauses in these instructions and in the for information about the installation requirements.

Safety Precautions
WARNING
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.
WARNING
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.
Failure to follow recommendations could result in death or serious injury.
Introduction
TR200 Programming Guide 17

WARNING
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 dis-
connected 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.
Consequently, disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be inadvertently energized. Failure to follow recommendations could
result in death or serious injury.
1. 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 ex-
clusively.
Note
When using the
Safe Stop function, always follow the instructions in the Safe Stop section of the Design Guide.
WARNING
Disconnect all electric power, including remote disconnects. Follow proper lockout/tagout procedures to ensure the
power cannot be inadvertently energized. Verify with an appropriate voltmeter that the unit is discharged. Failure to
disconnect power and ensure unit is discharge before servicing could result in death or serious injury.
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.
Failure to follow recommendations could result in death or serious injury.
Hoisting applications:
The frequency converter functions for controlling mechanical brakes cannot be considered as a primary safety
circuit. There must always be a redundancy for controlling external brakes.
Introduction
18 TR200 Programming Guide

Protection Mode
Once a hardware limit on motor current or dc-link voltage is exceeded the drive 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 drive while
re-establishing full control of the motor.
In hoist applications “Protection mode” is not usable because the drive 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 drive will trip immediately if one of the hardware limits is exceeded.
Note
It is recommended to disable protection mode in hoisting applications (par.14-26 Trip Delay at Inverter Fault =
0).
