Legal information

Warning notice system

This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are graded according to the degree of danger.

DANGER

indicates that death or severe personal injury will result if proper precautions are not taken.

WARNING

indicates that death or severe personal injury may result if proper precautions are not taken.

CAUTION

indicates that minor personal injury can result if proper precautions are not taken.

NOTICE

indicates that property damage can result if proper precautions are not taken.

If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage.

Qualified Personnel

The product/system described in this documentation may be operated only by personnel qualified for the specific task in accordance with the relevant documentation, in particular its warning notices and safety instructions. Qualified personnel are those who, based on their training and experience, are capable of identifying risks and avoiding potential hazards when working with these products/systems.

Introduction

1

Users of power supply systems for industrial applications, infrastructure and buildings are setting ever higher standards of the flexibility, transparency and communication capability offered by these systems. Intelligent switching devices are networked via communication systems and play an important role in industrial production and building management.

The standards expected of molded case circuit breakers in terms of their electrical and mechanical properties, their adaptability and cost effectiveness coupled with the ongoing trends in favor of rationalization and automation have greatly accelerated advances in the design of molded case circuit breakers over recent years.

In order to allow continuous monitoring of installations and achieve optimum metering of power supply and consumption with efficient process integration, it is important to consider two factors, i.e. the design of the required measuring points and early planning of the power distribution components which need to be monitored.

The following information is important to this process:

●Structure of the power distribution system

●Components of the power supply system

●Position of components in the power distribution system

●Allocation of power demands according to planned usage scenarios

For different levels and power distribution components, it is important to take into account the measurements and signals/feedback required during operation as well as various other requirements with respect to:

●Critical areas of the process

●Availability of loads

●Billing data (plausibility, contract monitoring, cost center management)

●Transparency for operation (measured variables, status)

●Capacity utilization (current metering)

Introduction

1.1 Security information

General information

When using communication-capable 3VA molded case circuit breakers, please observe the following information:

Safety-relevant information

When working on or around electrical equipment, appropriate safety procedures must be followed. Proper isolation actions must be directly measured and verified. Operational or power status as directly provided by installed components, including the 3VA molded case circuit breaker, is not sufficient by itself to determine the operational or power status of the system. Independent verification is required.
