PHOENIX CONTACT 3209594 Ground Modular Terminal Block Instruction Manual

Ground terminal with multi-conductor push-in connection for use in potentially explosive areas

The terminal is designed for connecting and linking copper wires in wiring spaces with “eb”, “ec” or “nA” 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

Snap the terminal blocks onto a corresponding DIN rail. For optical or electrical isolation, partition plates or covers can be inserted between the terminal blocks. When the terminal blocks are arranged in rows, fit the end terminal with the open half of the housing with the corresponding cover. 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.

Note : When fixing terminal blocks with other certified components, ensure that the required air clearances and creepage distances are observed.

Use of bridging jumpers

For this purpose, the contact tab of the plug-in bridge must be disconnected for the skip PE terminal to be disconnected.

NOTE : Using skip bridging from the ground terminals reduces the rated voltage of the bridged basic terminal bloc

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. Solid or stranded conductors with ferrules can be connected directly without tools. Insert the conductor into the connection opening of the terminal block up to the stop. With small conductor cross sections and stranded conductors without ferrules, you must open the terminal point before inserting the conductor. To do so, push the integrated push button down using a bladed screwdriver (tool recommendation, see accessories).

Acceptance criteria

• The suitability of the mounting equipment and the mounting method must be assessed in the end application.
• The connection cables at the terminal blocks must be adequately insulated for the voltages. The clearance between conductor insulation and the metal of the terminal point may not exceed 1 mm (see stripping length).
• During operation, the terminal blocks may not be used in an ambient temperature lower than -60°C or higher than +110°C.
• The terminal blocks have been rated for use in a housing with a minimum requirement of IP54. The suitability of the housing for the end application for increased safety is to be taken into consideration.
• The terminal points for the external connections of these terminal blocks have been rated in accordance with ANSI/UL 486E “Equipment Wiring Terminals for Use with Aluminum and/or Copper Conductors”. The suitability of the terminal points must be assessed during the final acceptance.
• The air clearances and creepage distances between bare live parts with different potentials are to be taken into consideration in the end application.
• The suitability of the terminal blocks is to be confirmed via a temperature-rise test in the end application.
• If used in connection and junction boxes, the specified design and installation regulations must be taken into consideration.
