PRACTICAL APPLICATIONS
OF THE GESIS® CLASSIC CONNECTOR SYSTEM
LIGHTING
LIGHTING CABLING - SWITCHED
Our solution with 3-pole wiring to the luminaires and an option for a 5-pole infrastructure for supply is typically installed in suspended ceilings and partially in hollow walls. Distribution is carried out via plug-in distribution blocks, and control is managed through decentralized room or building automation. With gesis® CLASSIC, the entire lighting can be executed in a plug-in manner. Switches or push buttons can also be integrated in a plug-in manner via switch distributors if required. The connection technology of the luminaires can be chosen flexibly.
LIGHTING CABLING - REGULATED, DALI OR 1-10 V
The suitable system from Wieland Electric consists of a 5-pole wiring, which is typically installed in suspended ceilings and partially in hollow walls. With a combination of gesis® CLASSIC and our flat cable solution gesis® NRG, a 7-pole infrastructure wiring, e.g., for extensive DALI systems, can be realized. The connection technology of the luminaires can be chosen flexibly. For large-scale applications with long cable lengths, a 7-pole gesis® NRG flat cable is also available for combining three-phase current and dimming signals.
ENERGY SUPPLY
WORKPLACE SUPPLY
With our solutions, you can realize a 3-pole wiring for the flexible and cascaded supply of (multiple) sockets in desks, furniture, and shelves. The various versions of gesis® NRG flat cables supply floor tanks with and without decentralized protection. The plug-in electrical installation can also be continued in furniture, creating clear interfaces and providing safety.
FLOOR BOX SUPPLY
Smaller systems are supplied via 3-pole wiring with round cables and distribution blocks. If more extensive or extended systems are to be supplied, our gesis® NRG flat cable 5G2.5/4 mm² is the ideal solution for structured supply of the floor tanks. The three-phase current supply up to shortly before the floor tanks ensures reduced energy consumption. The availability of multiple cable colors facilitates the separation of networks (power/data or audiovisual/security). The 3-pole, plug-in tap-offs with free phase selection also enable flexible load distribution. Floor tanks are available directly from various system partners in plug-in design ex-works. Upon request, they can also be supplied with decentralized protective devices (MCB, RCCB/MCB).

DADO TRUNKING
Baseboard ducts demonstrate their strengths wherever flexibility is required. Our gesis® NRG flat cables 5G2.5/4 mm² provide you with flexibility. Thus, an energy-efficient and easy-to-install solution for three-phase current supply up to shortly before the socket is available. Thanks to different cable colors, the separation of networks (power/data or audiovisual/security) is facilitated. The 3-pole, plug-in tap-offs with free phase selection also enable flexible load distribution.

SUNSHADE SYSTEMS AND SUN PROTECTION
WINDOW BLINDS (KNX, SMI)
The direct wiring between control and conventional drives is carried out using 4-pole gesis® CLASSIC variants. When modern SMI drives are used, the wiring to the drives is implemented using 5-pole gesis® CLASSIC round cables or gesis® NRG flat cables, in which control signals and power are conducted together. With the decentralized KNX system gesis® FLEX, the effort for the wiring of sun protection systems can be extremely reduced. Ideally, these actuators are supplied via a 7-pole gesis® NRG flat cable, which provides both three-phase current and the KNX network.
FOUR ESSENTIAL GESIS® SYSTEM COMPONENTS,
ONE PERFECT SOLUTION
DESIGNED FOR SEAMLESS INTEGRATION:
Our electrical installation system, consisting of connectors, pre-assembled cables, distributors, and device connections, is designed to implement any project effortlessly and error-free. Each component is precisely tailored to its task to ensure seamless integration.
CONNECTORS
Connectors serve as the basic element of plug-in electrical installations. They are used in facilities to make initial connections or to connect cables that cannot be pre-assembled and brought into the construction, such as when cables are pulled through pipes. Our systems are installation connector systems approved according to IEC EN 61535.
PRE-ASSEMBLED CABLES
Pre-assembled cables enable extremely fast and error-free installation. They are available in various pole numbers, cross-sections, cable types, lengths, and with different connectors. Wieland manufactures pre-assembled cables industrially, ensuring quality tested pieces on the construction site.
DISTRIBUTORS
The exclusive use of connectors and cables would only allow for 1:1 connections in a star structure. Our diverse distribution elements with various geometric layouts and different input/output combinations enable an effective, clear, and flexible tree structure.
DEVICE CONNECTIONS
Device connections can be directly integrated into equipment such as lights or system distributors. They serve as the interface from the plug-in electrical installation to the end user. The connections can be integrated as soldering parts on the circuit board or in screw/spring-loaded versions into the product housing.

WARNING
NO COMPATIBILITY BETWEEN CONNECTOR SYSTEMS FROM DIFFERENT MANUFACTURERS
Mixed connections between Wieland GST® connectors and connectors from other manufacturers can endanger the health and safety of people, animals and property.
Mixed connections between Wieland GST® connectors and connectors from other manufacturers can lead to the loss of the presumption of conformity according to Section 4 of the 1st ProdSV (Low Voltage Directive). Connectors from other manufacturers may not be made available or offered on the market in combination with Wieland GST® connectors or with the statement "Compatible with Wieland GST® connectors".
Explanation:
The Wieland gesis® CLASSIC installation connector system consists of GST® connectors, GST® device connectors, GST® distribution blocks and pre-assembled variants with different cable cross-sections and different connection techniques. All GST® products are certified in accordance with the harmonised standard EN IEC 61535 and are marketed by us for the establishment of a permanently pluggable connection in electrical installation systems.
IEC EN 61535 is a product standard and only regulates the requirements for product design; as a product standard, EN IEC 61535 does not contain any specifications for the design of connectors; i.e. unlike design standards (e.g. for the manufacture of earth contact connectors), codings and mating face can be freely selected by the manufacturers and can also be further developed within an installation connector family. This design freedom means that mechanical pluggability alone does not establish compatibility between connectors from different manufacturers.
Accordingly, the product standard IEC EN 61535 stipulates that only installation connectors from the same manufacturer should be used for installations, as this is the only way to ensure safe power transmission over a long period of time.
