bus line 150 m Communication protocols Cross-section Length 2 0.75 mm² – Max. 350 with 0.50 mm² 500 m Cable length test report LUXMATE PROFESSIONAL A 350 350 m B 350 m LM-BV B A . 350 with 0. – For tracks/trunking: bus lines should be cross-linked least every m. The loop resistance measured must not exceed ohms! If loop resistance between and ohms is measured, the service report must indicate that the bus line too long; electrician must inform­ ed! If the loop resistance measured ohms higher, commissioning will terminated! The cable length calculated follows: Cable length loop resistance rho cross-section/ divided two L rho 2 A cross-section/rho for copper LUXMATE guidelines: 1.5 mm2 cross-section max. 500 with 1.C.108 The Lighting Handbook LUXMATE bus: Bus line and cable lengths Bus line – Twisted two-core line lay each 5 metres) for low-voltage installation Cable lengths – Overall length for one bus power supply: max.75 mm² 250 m 2 1. bus line 500 m 1. 500 with 1.75 mm² – Max. bus line 250 m 0. – Bus and mains one cable 1. Voltage measurement (VOLT): measurement bet­ ween and D.0 mm2 cross-section max. bus line 300 m/ with 0.5 mm² – From bus power supply the most distant LUXMATE device (A,B): – Max.50 mm² 150 m 2 0. 1000 m – Between LUXMATE devices (AB): – Max. voltage Current measurement (AMPERE): measurement B1 or measured value must not exceed 150 mA Loop resistance (OHM): disconnect LM-BV from power, establish wire bridge LM-BV between B1 and B2, perform measurement the last actuator of the bus line between and B2.5 mm2 cross-section max.5 mm² – Loop resistance bus circuit must not exceed ohms (applies all components of the bus power supply).75 mm2 cross-section max.8 cable, both pairs must connected 0.00 mm² 300 m 2 1.5 mm²) are admissible only for stub lengths each
