Guidelines

Guidelines for Handling Electrostatic Sensitive

Devices

(ESD)

What Does

ESD

Mean?

Almost all SIMATIC–TELEPERM modules contain many integrated blocks or elements which use

MOS technology. The technology used makes these electronic components very sensitive to

overvoltages

and thus to electrostatic discharge.

The German abbreviation for such modules is

“EGB”:

Elektrostatisch

(2efahrdeten

Elauelemente

EJaugruppen

Next to this abbreviation you will often find the common international abbreviation

“ESD”: Electrostatic Sensitive

!2evice

When found on cabinets, module

subracks

or packaging, the symbol shown below indicates that

electrostatic sensitive components have been used in this device and the module is thus sensitive

to touch.

ESDS can be destroyed by voltages and energies far below those perceived by humans. Such

voltages can even occur when a component or a module is touched by a person who is not statical-

ly discharged. Components which have been subjected to such

overvoltages

can usually not be

immediately identified as defective since a malfunction may not occur until the module has been in

operation for a longer period of time.

To be perceived by humans, the following minimum voltages are required:

– To be felt – 3500 volts

– To be heard – 4500 volts

– To be seen – 5000 volts

But a fraction of this voltage can already damage or destroy electronic components.

Components which have been damaged, overloaded or weakened by static discharge can

mal-

function temporarily when average technical specifications are deviated from. A few examples are

listed below.” -

When Does a Static Charge Occur?

You can never be absolutely certain that you yourself or the materials and tools you are using are

not electrostatically charged.

Small charges of up to 100 V are common but these can increase to 35,000 V in a very short time!

Examples:

– Walking on carpeting

– Walking on plastic -

flooring

– Sitting on upholstered

chair

– Unsoldering device

made of plastic

– Plastic coffee cups

– Plastic covers

– Books and pads with

synthetic binding

Important Protective Measures Against Static Charging

Since most plastics have a strong tendency to charge, it is imperative that they be kept away

from sensitive components.

Be sure to provide good grounding of people, your workplace and the packaging when working

with electrostatic sensitive components.

Handling

ESD

Modules

As a matter of principle, electronic modules should not be touched unless the work to be per-

formed on them makes this absolutely necessary.

Components should not be touched unless

– you are continuously grounded with an

ESD

bracelet

– you are wearing

ESD

shoes or

ESD

shoe protective

grounding strips on an

ESD

floor.

Before touching an electronic module, your own body must be discharged. The easiest way to

do this is to touch a conductive, grounded object (e.g., blank metal parts of switching cabinets,

water pipes, etc.) immediately prior to touching the component.

Modules should not come in contact with chargeable and highly insulating materials (e.g., plas-

tic foil, insulating tabletops, synthetic fiber clothing).

Modules should only be placed on conductive surfaces (e.g., table with

ESD

covering, conduc-

tive

ESD

foam,

ESD

packaging bag,

ESD

shipping container).

Do not allow modules in the vicinity of CRTs, monitors or television sets (minimum distance to

the screen

>10

cm).

Measuring and Modifying

ESD

Modules

●

Measurements may not be performed on the modules unless

– the measuring device is grounded (e.g., with protective conductor)

– the measuring head is briefly discharged (e.g., touching blank metal part

of the controller housing) prior to measuring when using a floating mea-

suring device.

●

For soldering use only a grounded soldering device.

6Shipping

ESD

Modules

As a matter of principle, modules and components must always be stored or shipped in conduc-

tive packaging (e.g.,

metallized

plastic boxes, metal cans).

When packaging is not conductive, the modules must be wrapped in conductive material prior to

packaging. For example, conductive foam rubber,

ESD

bags, household aluminum foil or paper

can be used (never use plastic bags or foil).

Be sure that the conductive packaging of modules with built–in batteries does not touch or short

circuit the battery connections (if necessary, cover the connections with insulating tape or material

beforehand).

The following facts require particular attention.

!Note

Even when devices of automation technology are designed to provide maximum

conceptual

safe~

(e.g., multi–channel setup), it is still absolutely essential to ad-

here precisely to the instructions in this manual since safety measures built into

the device/system to prevent dangerous errors can be rendered useless by im-

proper handling; incorrect handling can also create additional danger sources.

Notes on

Safetv

Notes on installation and maintenance of the product – based on the application – are listed be-

low.

, Warning

The safety and accident prevention regulations applicable to the specific appli-

cation must be adhered to.

Built–in devices for housings or cabinets may only be used and operated when

completely installed in the housing or cabinet; desktop or portable models may

only be used and operated when the housing is closed.

A power disconnector switch or a fuse must be provided in the building installa-

tion for facilities with a fixed connection (stationary devices/systems) without

all–pole power disconnector switches and /or fuses. The facility must be con-

nected to a protective conductor.

The grounded protective contact electrical outlet for devices/systems with per-

manently connected, non–removable connection lines and without all–pole

power disconnector switches must be installed near the device and be easily

accessible.

Before commissioning devices operated with power network voltage, check to

determine whether the set nominal voltage range matches the local power

vol–

tage.

When a 24–V supply is used, a reliable electrical separation of extra low

vol–

tages

must be provided. Use only powerpacks manufactured in accordance

with

IEC

364–4–41 or HD 384.04.41

(VDE

0100, part 410).

Fluctuations or variations of the power voltage from the nominal value may not

exceed the tolerance ranges stated in the technical specifications. Otherwise

the occurrence of malfunctions and dangerous states on the electrical module

systems cannot be excluded.

Measures must be provided by which an interrupted program can be properly

restarted aftera drop in voltage or a power loss. This must not cause dangerous

operating situations even for short times. If necessary, “emergency OFF” must

be forced.

Releas~

ing the “emergency OFF” system must not cause uncontrolled or undefined re-

starts.

Caution

. Installation of connection and signal lines must be such that inductive and

capacitive interferences do not affect the automation functions.

●

Installation of automation systems and their operating components must be

such that they are sufficiently protected against accidental activation.

. Appropriate safety measures must be provided on the 1/0 coupling of the

hardware and software to prevent a line or wire break from causing undefined

states in the automation system.

6Active and Passive Errors of an Automation System

●

Depending on the task to be performed by an electronic automation system, both active and

passive errors can bedangerous errors. In a drive control system, for example,

theactive

error

is usually dangerous since it can cause the drive to be switched on. In contrast, a passive error

in a message function can prevent a dangerous operating state from being reported.

●

The distinction between possible errors and their classification as dangerous or not dangerous

based on their task is

impottant

to all safety measures concerning the-delivered product.

Warning

Everywhere where errors in the automation system can cause substantial pro–

petty damage or even personal injury (i.e., can be dangerous errors), additional

external measures must be taken or systems created which will ensure or force

safe operation when an error occurs (e.g., with an independent limit value

switch, mechanical locks, etc.).

7Maintenance and Repair Procedures

When measurements or tests must be performed on an active device, the specifications and in-

structions contained in accident prevention regulation VBG 4.0, and

“Permissible Deviations

during Work on Active Parts” in particular, must be complied with. Suitable electrical tools must be

used.

, Warning

\—

●

Repairs on an automation system may only be performed by Siemens Service

personnel or by repair shops authorized by

Siemens.

When replacing parts

or components, use only parts contained in the spare parts list or listed under the

section on spare parts in this manual. Unauthorized opening and faulty repairs

can result in death or severe personal injury, and substantial property damage.

Before opening the device

always

pull the power plug or open the disconnection

switch.

When replacing fuses, use only the types specified in the technical specifications

or the maintenance instructions of this publication.

Do not throw batteries in an open fire and do not perform soldering on the body of

the battery. Danger of explosion (maximum temperature of 100° C). Do not

open or recharge lithium batteries or batteries containing mercury. When replac-

ing, use only the same types.

Always dispose of batteries or accumulators at a special waste collection point.

Use of monitors:

Faulty work (particularly changes in the high–voltage or installation of another

type of picture tube) can result in increased emission of X–rays. A device which

has been thus modified no longer meets certification criteria and may not be op-

erated.
