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:

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)!
