Introduction to the manual
Contents of this chapter
This chapter contains information on the manual, gives safety instructions and other
general information for the reader.
Applicability
The manual applies to cabinet-built ACS880 single drives and multidrives with the options:
•+L513+Q971 and +2L513+Q971
(+3L513+Q971 available as an application-engineered option)
•+3L514+Q971, +5L514+Q971 and +8L514+Q971.
The motor thermal protection functions described in this manual are certified, with an
EU-type examination certificate, as protective systems in accordance with the ATEX
Product Directive 2014/34/EU (previously 94/9/EC).
Safety instructions
Only qualified specialists are allowed to install, control and maintain the ATEX-certified
motor thermal protection functions (see EN/IEC 60079-14). Obey all safety regulations
required with application of Ex motors in Zone 1/21 (equipment category 2) or Zone 2/22
(equipment category 2 or 3).
WARNING! Read and obey all safety instructions given for the drive. If you ignore
them, injury or death, or damage to the equipment can occur.
This manual does not repeat the complete safety instructions of the drive but it only
includes the instructions related to the scope of this manual. The general instructions are
given in this section and the option-specific instructions in the appropriate chapter.

10 Introduction to the manual
In addition to this manual,
•for ACS880 single drives, see the drive hardware manual
•for ACS880 air-cooled multidrives, see Safety instructions for ACS880 multidrive
cabinets and modules (3AUA0000102301 [English]).
The function described in this manual activates the Safe torque off (STO) function of the
drive/inverter unit. The STO function of the ACS880 drives is certified (SIL 3 according to
EN/IEC 61800-5-2 and IEC 61508). For a detailed description of the STO function, see the
hardware manual of your drive/inverter unit.
WARNING! The functions described in this manual do not disconnect the voltage
of the main and auxiliary circuits from the drive. Never work on the electrical parts
of the drive or the motor before you have also disconnected the drive system from
the electric supply, from rotating permanent magnet motors and from rotating motors
equipped with sine filters, and made sure by measuring that there is no dangerous voltage
present.
WARNING! The STO function of ACS880 drives cannot prevent the intermediate
DC current from flowing through, and heating up, the motor in case a short-circuit
occurs in the output stage of the drive. The supplier must take this into account
when planning the protection of the installation.
Note: When you connect the temperature sensor(s) of the Ex motor to the drive STO
terminals through a relay, ensure the availability of required reinforced (double) insulation
between the main circuit (motor) and the control unit. For example, the insulation of the
temperature sensor in the Ex motor and the insulation of the protection relay affect the
insulation of the whole circuit. All Ex motors manufactured by ABB have basic insulation
between the main circuit and the temperature sensor. Similarly, ABB protection relays
have basic insulation between the sensor circuit and relay output. This ensures double
insulation for the ATEX-certified motor thermal protection function between the main circuit
and the drive control unit.
Example circuit diagrams of this manual
The purpose of the example circuit diagrams is to help in understanding the operation of
the ATEX-certified motor thermal protection functions. The diagrams do not cover all
possible details and variants of the drives. The component designations do not necessarily
match each drive.
WARNING! Never connect, test or measure a drive based on the diagrams of this
manual. Each delivery is unique. Before you start the work on the electric circuits
of a drive, always refer to the delivery-specific circuit diagrams.

16 ATEX-certified motor thermal protection function with PTC thermistor relays (+L513+Q971)
Description
This protection function monitors the temperature of a motor with PTC resistor sensors
(PTC thermistors) in a potentially explosive atmosphere. It is possible to
•monitor either the motor’s bearings or windings (+L513+Q971) or
•monitor both the motor’s bearings and windings (+2L513+Q971 or +3L513+Q971).
The function is activated when the PTC sensor resistance exceeds the overtemperature
limit. The function activates the Safe torque off (STO) function of the drive. This disables
the control voltage of the power semiconductors of the drive output stage. This prevents
the inverter from generating the torque required to rotate the motor. The motor coasts to a
stop.
ACS880-07/17/37 drives with the option +Q978: Also the main contactor/breaker is
opened.
ACS880-07 drives, frames nxDXT + nxR8i with a main contactor/breaker (option +F250/
+F255) and ACS880-17/37 drives, frames nxR8i + nxR8i: When the STO function is
activated in the inverter unit, the main contactor/breaker is opened after user-defined delay
(defined with parameter 94.11, the default value is 600 s). See hardware and firmware
manuals for more information.
Other safety functions in the drive can also use the STO function. In addition, the FSO
module can be included in the activation sequence of the ATEX-certified motor thermal
protection function. See the circuit diagrams delivered with the drive for the actual safety
circuitry.
The FSO safety functions module (FSO-12 or FSO-21) is an optional device used with the
ACS880 drives to implement safety functions. When installed, it reserves the standard
STO connection of the drive. In this case, the FSO module activates the STO function of
the drive (that is, opens the drive STO circuit) either immediately or after a deceleration
ramp.
You can implement the motor thermal protection function with or without an FSO safety
functions module:
•Without an FSO module, the opening contacts of the PTC relay(s) open the STO
circuit of the drive (see section Without an FSO module on page17).
•With an FSO module, the opening contacts of the PTC relay(s) activate the STO or
Safe stop 1 (SS1) function of the FSO module and the FSO module opens the STO
circuit of the drive (see section With an FSO module on page 18). For more
information on the safety functions of the FSO module, see FSO-12 safety functions
module user’s manual (3AXD50000015612 [English]) or FSO-21 safety functions
module user’s manual (3AXD50000015614 [English]).
Always consider which stop category (0 = immediate STO or 1 = delayed STO after SS1)
is more appropriate for the motor in overtemperature situations.
The protection function circuit is motor specific, also in multidrives where several motors
are connected. The function stops only the motor where overtemperature is detected.
It is possible to get information on the status of the protection function by means of a
normally-open contact. The information can be obtained separately from the bearing and
stator thermistors. The contact can be wired to a digital input on the drive control unit or to
an external control system. For instructions, see section Wiring on page 23.
The temperature measurement circuit of ABB Ex motors has basic insulation. For
information on the insulation of the thermistor relays, see its data starting on page 56.

ATEX-certified motor thermal protection function with PTC thermistor relays (+L513+Q971) 17
Operation principle
Without an FSO module
1. When the motor temperature rises to the thermistor wake-up level, the resistance of
the thermistor increases sharply.
2. The PTC thermistor relay detects the change and indicates motor overtemperature
through its output contacts.
3. The opening contacts of the PTC relay(s) open the STO circuit of the drive. This
prevents the drive from generating the torque required to rotate the motor.
4. The drive generates an STO indication (parameter 31.22, see page 44).
5. If the auxiliary contacts of the PTC relays are wired to a digital input, the loss of the
signal triggers a motor overtemperature indication in the drive (see page 44).
6. After the motor temperature has decreased to normal, the user resets the PTC relay(s)
using remote reset buttons (or the buttons on the PTC relays themselves). See the
circuit diagrams of the delivery.
7. Optional: The user resets the drive faults either from the reset source defined by the
user (parameter 31.11, see page 45) or locally with the drive control panel:
•the STO fault in the drive (if configured with drive parameter 31.22, see page 44)
•the motor overtemperature fault in the drive (if configured, see page 44).
WARNING! We recommend that you do not use the autoreset setting (that is,
short-circuit the reset switch terminals of the PTC relay) with a safety device
protecting an Ex motor.

18 ATEX-certified motor thermal protection function with PTC thermistor relays (+L513+Q971)
With an FSO module
1. When the motor temperature rises to the thermistor wake-up level, the resistance of
the thermistor increases sharply.
2. The PTC thermistor relay detects the change and indicates motor overtemperature
through its output contacts.
3. The opening contacts of the PTC relay(s) switch off the voltage to terminal X113:4 of
the FSO module (this is configured as the input of the STO [or SS1] function in the
FSO module).
4. The FSO module opens the STO circuit of the drive either immediately (STO function)
or after a deceleration ramp (SS1 function). This prevents the drive from generating
the torque required to rotate the motor.
5. The drive generates an STO indication (parameter 31.22, see page 44).
6. The FSO module generates an STO indication (parameter FSOGEN.61, see
page 47).
7. If the auxiliary contacts of the PTC relay(s) are wired to a digital input, the loss of the
signal triggers a motor overtemperature indication (see page 44).
8. After the motor temperature has decreased to normal, the user resets the PTC relay(s)
using remote reset buttons (or the buttons on the PTC relays themselves). See the
circuit diagrams of the delivery.
9. Optional: The user resets the drive faults either from the reset source defined by the
user (parameter 31.11, see page 45) or locally with the drive control panel:
•the STO fault in the drive (if configured with drive parameter 31.22, see page 44)
•the motor overtemperature fault in the drive (if configured, see page 44),
10. Optional: The user resets the safety function in the FSO module with the reset button
(if a reset circuit is wired and configured, see page 46 and the next section).

WARNING! We recommend that you do not use the autoreset setting (that is,
short-circuit the reset switch terminals of the PTC relay) with a safety device
protecting an Ex motor.
Resetting the ATEX-certified motor thermal protection
function
A manual reset is mandatory in the temperature protection function, if it is required for
ensuring the compliance of the system with Ex/ATEX regulations.The manual reset is set
in the ATEX-certified PTC thermistor relay at the factory. This makes sure that the ATEX
requirement on manual reset is fulfilled and you do not have to configure any faults in the
drive (or FSO) parameters.
If you change the manual reset setting in the PTC thermistor relay, make sure that the user
cannot restart the drive without a manual reset.
You can configure the manual reset either in:
•the drive with the motor overtemperature or STO indication parameters (see
page 44)
•the FSO module by connecting a reset circuit to the FSO module (see page 46).
ACS880-07/17/37 drives with the option +Q978 or +Q979 (Emergency stop): In these
safety functions, a reset circuit is connected to the FSO module and the user must reset
the safety function with the emergency stop reset button. In this case, the user must reset
also the ATEX-certified motor thermal protection function with the emergency stop reset
button. Do not change this setting.
Indications of the ATEX-certified motor thermal
protection function
An indication of the safety function can come from several sources:
•the motor overtemperature indication in the drive
•the STO indication in the drive
•the STO indication in the FSO module.
If you want to avoid parallel indications in overtemperature situations, you can set one or
several of the indication parameters value to No indication (or None) or Event:
•the motor overtemperature indication with drive parameters 31.01...31.02 or
35.11...35.12 (see page 44),
•the STO indication in the drive with drive parameter 31.22 STO indication run/stop
(see page 44),
•the STO indication in the FSO module with FSO parameter FSOGEN.61 STO
indication ext request (see page 47).
Note: If the PTC thermistor relay is not in the manual reset mode, make sure that at least
one of these indications generates a fault.
