Safety instructions

Contents of this chapter

This chapter contains the safety instructions which you must obey

when you install, operate and do maintenance on the safety functions

of a drive.

Use of warnings and notes

Warnings tell you about conditions which can cause injury or death,

or damage to the equipment. They also tell you how to prevent the

danger. Notes draw attention to a particular condition or fact, or give

information on a subject.

The manual uses these warning symbols:

WARNING!

Electricity warning tells about hazards from electricity which

can cause injury or death, or damage to the equipment.

Safety instructions 9

WARNING!

General warning tells about conditions, other than those

caused by electricity, which can cause injury or death, or

damage to the equipment.

WARNING!

Electrostatic sensitive devices warning tells you about the risk

of electrostatic discharge which can cause damage to the

equipment.

ATEX-certified motor thermal protection functions

Only qualified specialists are permitted 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!

Obey the safety instructions of the drive. If you ignore

them, injury or death, or damage to the equipment can

occur.

This manual does not contain the complete safety instructions of the

drive. 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 applicable chapter.

In addition to this manual:

• For ACS880 single drives, see the drive hardware manual

• For ACS880 air-cooled multidrives, multidrive modules and single

drive modules, see ACS880 multidrive cabinets and modules

safety instructions (3AUA0000102301 [English])

10 Safety instructions

28

• For ACS880 liquid-cooled multidrives, multidrive modules and

single drive modules, see ACS880 liquid-cooled multidrive

cabinets and modules safety instructions (3AXD50000048633

[English]).

WARNING!

The functions described in this manual do not disconnect the

voltage of the main and auxiliary circuits from the drive. Do

not do work on the drive, motor cable or motor when they are

energized. Before you start the work, do the steps in section

Electrical safety precautions (page 12).

WARNING!

If a short-circuit occurs in the output stage of the drive, the

STO function does not prevent the intermediate DC current

from flowing through and heating up the motor. The system

integrator must take this into account when planning the

protection of the installation.

Safety instructions 11

Electrical safety precautions

These electrical safety precautions are for all personnel who do work

on the drive, motor cable or motor.

WARNING!

Obey these instructions. If you ignore them, injury or death,

or damage to the equipment can occur.

If you are not a qualified electrical professional, do not do

installation or maintenance work.

Go through these steps before you begin any installation or

maintenance work.

1. Clearly identify the work location and equipment.

2. Disconnect all possible voltage sources. Make sure that

re-connection is not possible. Lock out and tag out.

• Open the main disconnecting device of the drive.

• Open the charging switch if present.

• Open the disconnector of the supply transformer. (The main

disconnecting device in the drive cabinet does not disconnect

the voltage from the AC input power busbars of the drive

cabinet.)

• Close the grounding switch or switches ([Q9], option +F259)

if present. Do not use excessive force as the switch has

electromagnetic interlocking.

• If the drive is equipped with a DC/DC converter unit (optional):

Open the DC switch-disconnector ([Q11], option +F286) of

the DC/DC converter. Open the disconnecting device of the

energy storage connected to the DC/DC converter unit

(outside the drive cabinet).

• Open the auxiliary voltage switch-disconnector (if present),

and all other possible disconnecting devices that isolate the

drive from dangerous voltage sources.

• In the liquid cooling unit (if present), open the motor protective

circuit breaker(s) of the cooling pumps.

12 Safety instructions

28

• If you have a permanent magnet motor connected to the

drive, disconnect the motor from the drive with a safety switch

or by other means.

• Disconnect any dangerous external voltages from the control

circuits.

• After you disconnect power from the drive, always wait 5

minutes to let the intermediate circuit capacitors discharge

before you continue.

3. Protect any other energized parts in the work location against

contact.

4. Take special precautions when close to bare conductors.

5. Measure that the installation is de-energized. If the measurement

requires removal or disassembly of shrouding or other cabinet

structures, obey the local laws and regulations applicable to live

working (including – but not limited to – electric shock and arc

protection).

• Use a multimeter with an impedance greater than 1 Mohm.

• Make sure that the voltage between the drive input power

terminals (L1, L2, L3) and the grounding (PE) busbar is close

to 0 V.

• Make sure that the voltage between the drive output terminals

(T1/U, T2/V, T3/W) and the grounding (PE) busbar is close

to 0 V.

• Make sure that the voltage between the drive DC busbars

(+ and -) and the grounding (PE) busbar is close to 0 V.

• Make sure that the voltage between the drive DC terminals

(R+/UDC+ and UDC-) and the grounding terminal (PE) is

close to 0 V.

WARNING!

The busbars inside the cabinet of liquid-cooled drives are

partially coated. Measurements made through the coating

are potentially unreliable, so only measure at uncoated

portions. Note that the coating does not constitute a safe

or touch-proof insulation.

Safety instructions 13

6. If the drive is not equipped with a grounding switch, install

temporary grounding as required by the local regulations.

7. Ask the person in control of the electrical installation work for a

permit to work.

Introduction to the manual

Contents of this chapter

This chapter gives basic information on the manual.

Applicability

This manual is applicable to the FPTC-02 module and to the Safe

motor temperature safety (SMT) function which uses the FPTC-02

module (option +L537+Q971).

Compatibility

The FPTC-02 module is compatible with:

• ACS880-01/11/31 drives

• ACS880-04/04XT/04F/04FXT/M04/14/34 drive modules

• ACS880-104/104LC inverter modules

• ACS880-07/17/37 and ACS880-17LC/37LC cabinet-built single

drives

• ACS880-107/107LC inverter units

• FSO-12 and FSO-21 safety functions modules

Introduction to the manual 15

• ACS880 primary control program version 2.10 or later. For the

compatibility of other control programs, contact your local ABB

representative.

Target audience

The manual is intended for people who install, start-up, use and

service the ATEX-certified thermistor protection module of the drive.

Read the manual before working on the drive. You are expected to

know the fundamentals of electricity, wiring, electrical components,

electrical schematic symbols and ATEX/Ex regulations.

Exclusion of liability

ABB is not responsible for the implementation, verification and

validation of the overall safety system. It is the responsibility of the

system integrator (or other party) who is responsible for the overall

system and system safety.

The system integrator (or other responsible party) must make sure

that the entire implementation complies with the instructions in this

manual, all relevant standards, directives and local electrical code,

and that the system is tested, verified and validated correctly.
