Installation Regulations

6.6 Installation Regulations

In the Federal Republic of Germany, various national regulations for the installation in explosive areas must be taken into consideration. The basis being the ElexV complemented by the installation regulation DIN VDE 0165/2.91. The following are excerpts from additional VDE regulations:

DIN VDE 0100 Installation in power plants with rated voltages up to 1000 V

DIN VDE 0101 Installation in power plants with rated voltages above 1 kV

DIN VDE 0800 Installation and operation in telecommunication plants including information processing equipment

DIN VDE 0185 lightning protection systems

The USA and Canada have their own regulations. The following are excerpts from these regulations:

NFPA 70

National Electrical Code Art. 500 Hazardous Locations

 

 

ANSI/ISA-RP

Recommended Practice

12.6-1987

Danger

For the use of WAGO-I/O SYSTEM 750 (electrical operating means) with Ex approval the observance of the following points is mandatory:

•The electrical operating means are exclusively suitable for applications in explosion endangered areas (Europe Group II, Zone 2 or America: Class I, Division 2, Group A, B, C, D) or in non-explosion endangered areas!

•Ensure that only approved modules of the electrical operating means will be used. Replacement of components can jeopardize the suitability of the system in explosion endangered zones!

•Only disconnect and/or connect electrical operating means when the voltage supply is isolated or when a non-explosive atmosphere has been ascertained!

•Adhere to the specified data regarding voltage supply and fusing. (See data on the fuse holder)!

Bit

Smallest information unit. Its value can either be 1 or

 

0.

Bitrate

Number of bits transmitted within a time unit.

Bootstrap

Operating mode of the fieldbus Coupler / Controllers.

 

Device expects a firmware upload.

Bus

A structure used to transmit data. There are two

 

types, serial and parallel. A serial bus transmits data

 

bit by bit, whereas a parallel bus transmits many bits

 

at one time.

Byte

Binary Yoked Transfer Element. A byte generally

 

contains 8 bits.

Data bus

see Bus.

Fieldbus

System for serial information transmission between

 

devices of automation technology in the process-

 

related field area.

Hardware

Operating system

Segment

Electronic, electrical and mechanic components of a module/subassembly.

Software which links the application programs to the hardware.

Typically, a network is divided up into different physical network segments by way of routers or repeaters.

Server

Device providing services within a client/server sys-

 

tem. The service is requested by the Client.

Subnet

A portion of a network that shares the same network

 

address as the other portions. These subnets are dis-

 

tinguished through the subnet mask.
