Ri4Power Modular outgoing feeder section Modular outgoing feeder sections are used for the installation of circuits with Switchgear Power supply outgoing feeders Controllers, switchgear units Fused outgoing feeders etc. in different compartments. The rated currents can be distributed via integrated distribution busbar systems. The following bar systems, see Table 3, are available for selection as distribution busbar systems. The rated currents Inc of the distribution busbar systems are likewise dependent on the protection category and the type of cooling.

With the indoor version, the switchgear may be mounted and connected directly onto the busbar system via the RiLine60 component adaptor system, whilst retaining form separation. Access to the connections on the adaptor and on the switchgear is always possible from the front. When configuring the compartment in a modular outgoing feeder section, care should be taken to ensure that the maxi- mum admissible rated current Inc of the distribution busbar system is not exceeded by the sum total of simultaneously loaded outgoing feeder circuits connected to that distribu- tion busbar system. If equipment is used within the compart- ment that produces a higher additional heat loss (frequency converters, power converters etc.), a separate heat loss and cooling calculation should be prepared for that compart- ment. This calculation must provide evidence of heat dissi- pation via an additional cooling device. The main busbar system may optionally be installed in the Busbar routed behind the Busbar routed in the roof, base or rear section at the top or bottom. When using compartment compartment (indoor) partial doors, front trim panels with a protection category as per the technical specifications should be used for the upper and lower termination of the modular equipment. The detailed configuration of the modular outgoing feeder panels should be taken from the valid Ri4Power assembly instructions. 2 - 51 Rittal Technical System Catalogue/Power distribution
