We recommend the use of 6 A fuses.  When using busbar systems, please note: The maximum voltage of the system being monitored must not exceed the nominal insulation volt- age of the measuring current transformers used in the RCMS system.  Select the cables and cable lengths according to the technical data onpage 86ff. If you use cables that are longer than those specified here, Bender cannot guarantee that the equipment will function safely.
