Important User Information

Solid state equipment has operational characteristics differing from those of

electromechanical equipment. Safety Guidelines for the Application, Installation

and Maintenance of Solid State Controls (Publication SGI-1.1 available from your

local Rockwell Automation sales office or online at http://www.ab.com/manuals/gi)

describes some important differences between solid state equipment and

hard-wired electromechanical devices. Because of this difference, and also because

of the wide variety of uses for solid state equipment, all persons responsible for

applying this equipment must satisfy themselves that each intended application of

this equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or

consequential damages resulting from the use or application of this equipment.

The examples and diagrams in this manual are included solely for illustrative

purposes. Because of the many variables and requirements associated with any

particular installation, Rockwell Automation, Inc. cannot assume responsibility or

liability for actual use based on the examples and diagrams.

No patent liability is assumed by Rockwell Automation, Inc. with respect to use of

General Description

When used with suitable safety components, the PowerFlex 700S

Safe-Off with Second Encoder option provides protection according to

EN 954-1:1997; Category 3 for safe-off and protection against restart.

The PowerFlex Safe-Off option is just one safety control system. All

components in the system must be chosen and applied correctly, to

achieve the desired level of operator safeguarding.

The PowerFlex Safe-Off option:

•Is designed to safely remove power from the gate firing circuits of

the Drive’s output power devices (IGBT’s). This prevents them from

switching in the sequence necessary to generate torque in the motor.

•Can be used in combination with other safety devices to provide

Category 0 (Coast) stop according to EN 60204-1 and NFPA 79.

•The Safe-Off option in the PowerFlex 700S provides Category 3

performance according to EN 954-1.

Important: The option is suitable for performing mechanical work on

the drive system or affected area of a machine only. It does

not provide electrical safety.

What Is the PowerFlex Safe-Off Option?

ATTENTION: To avoid an electric shock hazard, verify that the

voltage on the bus capacitors has discharged before performing any

work on the drive. Measure the DC bus voltage at the +DC and -DC

terminals or test points (refer to your drive’s User Manual for

locations). The voltage must be zero.

ATTENTION: In safe-off mode, hazardous voltages may still be

present at the motor. To avoid an electric shock hazard, disconnect

power to the motor and verify that the voltage is zero before performing

any work on the motor.

General Description 3

The Safe-Off with Second Encoder option meets the following safety

standards:

•EN 60204-1 Safety of machinery – Electrical equipment of machines

– Part 1: General Requirements

•EN 954-1:1997; Category 3 - Safety-related parts of control systems

Conformity with the Low Voltage (LV) Directive and Electromagnetic

Compatibility (EMC) Directive has been demonstrated using

harmonized European Norm (EN) standards published in the Official

Journal of the European Communities. PowerFlex Drives comply with

the EN standards listed below when installed according to the User and

Reference Manuals.

CE Declarations of Conformity are available online at:

http://www.ab.com/certification/ce/docs.

Low Voltage Directive (73/23/EEC)

•EN50178 Electronic equipment for use in power installations

EMC Directive (89/336/EEC)

•EN61800-3 Adjustable speed electrical power drive systems Part 3:

EMC product standard including specific test methods.

4Installation and Wiring

Installation and Wiring

Installation must be in accordance with the following steps and must be

carried out by suitably competent personnel. This device is intended to

be part of the safety related control system of a machine. Before

installation, a risk assessment should be performed to determine whether

the specifications of this device are suitable for all foreseeable

operational and environmental characteristics of the machine to which it

is to be fitted.

At regular intervals during the life of the machine check the safety

function for proper operation. How frequently the safety function is

checked is dependent on the safety analysis of the machine section

controlled by the drive.
