Hager. System components Unit, assembly or equipment as an integral part of a system or subsystem. Hager is a producer of matched and tested system components. Hager has provided verification of the design by means of tests, calculations or by applying the design rules and makes this data available to the manufacturer of the switchgear and controlgear assembly.
Page 18: Project Planning And Constructing Power Switchgear
The manufacturer of the switchgear and controlgear as- sembly must obtain Hager's design verification of the parts used. If this verifi- cation is not available or if the manufacturer does not use type-tested parts, the manufacturer of the switchgear and controlgear assembly must provide the design verification.
Page 19: Special Operating Conditions
About this System Manual Main terms 1.5.5 Special operating conditions The user must inform the switchgear and controlgear assembly manufacturer of special operating conditions. The relevant special requirements must also be fulfilled or special agreements must be made between the user and the manufacturer.

Page 166: Compliance With Emc Rules
Installation and connection Compliance with EMC rules Compliance with EMC rules When installing ready-to-connect switchgear and controlgear assemblies, electromagnetic compatibility must be ensured. The electrician must observe the known installation regulations as well as the manufacturer's regulations. This is done to rule out mutual interference of the installed equipment and the immediate surroundings.
Page 167 Installation and connection Compliance with EMC rules Testing and verifying immunity and interference EMC requirements must be verified by tests in accordance with the EN 61439 standard for finished switchgear and controlgear assemblies. Installed operating equipment must be designed according to the defined environment (environment A or environment B) with regard to its immunity.
Page 168: Measures To Ensure Emc-Compliant Installation
Implementing the spatial separation of EMC areas Spatial separation of the EMC areas in the switching enclosure is beneficial. With its clear spatial distribution, the unimes H power distribution system supports the functional and spatial separation of the functional areas. Make sure to divide into different EMC areas of different power/interference levels in the enclosure.
Page 169 Installation and connection Measures to ensure EMC-compliant installation Line routing and cabling ➢ Spatially separate the different line groups. ➢ Route the lines that are susceptible and sensitive to interference sepa- rately. Avoid routing the lines that are susceptible and lines that are sensitive to interference in one cable compartment.
Page 170 Installation and connection Measures to ensure EMC-compliant installation Integrate the cable ducts in the equipotential bonding system Metallic cable ducts that are integrated in the equipotential bonding system between two switching enclosures must be unpainted, metallic bare connections fixed directly on the switching enclosure. Metallic cable ducts must be conductively connected and fastened.

Page 223: 14 Glossary
Glossary 14 Glossary Air circuit breaker (ACB). Compared to compact circuit breakers (MCCB = Moulded-Case Circuit Breaker), air circuit breakers have a larger volume and are designed for higher rated currents. A circuit breaker is a mechanical switchgear unit that can switch on, route, and switch off currents in the circuit under operating conditions.
Page 224 They determine the short-circuit resistance and thus the operational safety of a low-voltage switchgear and controlgear assembly. The busbar systems of the unimes H power distribution system can be designed with standard Cu busbars. The drill-free connection technology reduces workloads and thus saves time and costs.
Page 225 Terminal compartment. The connection points of the outer conductors/cables (interfaces) are located in the cable compartment. Some enclosure types of the unimes H power distribution system are provided as versions with an integrated cable compartment to the left or right of the device compartment.
Page 226 Glossary Distribution busbar system (F-SaS) Field distribution busbar system (F-SaS). Distribution busbars establish the connection between busbars of the main busbar system and the installed devices. The distribution busbar system F-SaS includes the busbar supports (F- SaS supports) and fastening and partition accessories in a field. Earthing connection The earthing connection includes all inactive conducting parts, such as casings, support rails, DIN rail, etc., which do not create a protective earthing connection...

Page 228 Glossary Hazard zone According to DIN VDE 0105-100, the hazard zone is an area around live parts in which the required insulation level is not ensured. When entering this area, there is the risk of electric current passing through the human body and/or arcing. All work preformed in the hazard zone must satisfy the conditions for work under voltage.
Page 229 Multi-pole busbar system that is routed in the enclosure of a switchgear and controlgear assembly. The main busbars of the enclosures of the power distribution system unimes H are connected via transport divider plates U-TT (U- TTS as a set) or the compact transport divider U-TTK. Distribution busbars can be connected to the main busbars.
Page 230 Range of components, according to the definition of the original manufacturer, that can be installed for different switchgear and controlgear assemblies in compliance with the manuals of the original manufacturer. The unimes H power distribution system is a type-tested switchgear and controlgear assembly for switchgear and controlgear assemblies according to EN 61439-1/-2.
Page 231 Glossary At the test position, the auxiliary circuit is connected in such a way that the integrated devices can be tested. At the test position, the withdrawable part is connected mechanically with the switchgear and controlgear assembly. Transport unit Complete switchgear and controlgear assembly or a part of a switchgear and controlgear assembly, which is not dismantled further or disassembled for transport.
Page 232 Glossary hoisting or lowering tools or material. Withdrawable part On power switchgear and controlgear assemblies, a withdrawable part is a removable part that can be moved from operating position to a disconnected position or a test position. It remains mechanically connected to the switchgear and controlgear assembly.
