**
Ground terminal with screw connection for use in potentially explosive areas
The terminal block is designed for connecting and joining copper conductors in wiring spaces with “eb” and “ec” types of protection.
Installation instructions Increased safety “e”
The terminal block must be installed in a housing which is suitable for the type of protection. Depending on the type of protection, the housing must meet the following requirements:
- Flammable gases: IEC/EN 60079-0 and IEC/EN 60079-7
- Combustible dust: IEC/EN 60079-0 and IEC/EN 60079-31
When arranging terminal blocks of other series and sizes, as well as other certified components in rows, ensure that the required air clearances and creepage distances are observed
You may install the terminal block in equipment with temperature class T6 (e.g. branch or junction boxes). The rated values must be adhered to. The ambient temperature at the installation position may not exceed +40°C. The terminal block may also be installed in equipment with temperature classes T1 to T5. For applications in temperature classes T1 to T4, ensure compliance with the highest permissible operating temperature at the insulating parts (see Technical Data, “Installation temperature range”).
Installation and connection
Installation on the DIN rail
Place the terminal block with loosened tensioning screw onto a corresponding DIN rail. Tighten the screw from the PE foot with the specified torque (see technical data). If the terminal strip is not protected against twisting, slipping or moving by other certified components, it must be fixed on both sides with one of the specified end brackets (see accessories). Observe the accompanying example when installing the accessories. (2)
Note: When fixing terminal blocks with other certified components, ensure that the required air clearances and creepage distances are observed.
Connecting the conductors
Strip the conductors to the specified length (see technical data). Stranded conductors can be fitted with ferrules. Crimp the ferrules using crimping pliers and ensure that the test requirements listed in DIN 46228 Part 4 are met. The length of the copper ferrules must equal the specified conductor stripping length. Insert the conductor into the terminal point up to the stop. Tighten the screw of the terminal point (tool recommendation, see accessories), adhere to the specified torque range. Recommendation: tighten all screws including those which are on terminal points that are not used.
