China OPTOTRONIC® OT 50/220-240/24 Constant Voltage LED Power supply for 24V LED - Modules Wiring and Connection • • • • • Ensure that the LED module load is within the range of rated voltage, current and power supply (see Technical data) Maximum output cable length is limited by EMI and cross diameter Use output cable sections adequate to the load demand The luminaire manufacturer is responsible for providing the required clearances and creepage distances and also for protection against electrical shock, especially for the line and load wires Wire preparation: Input Mains Terminal Output LED Terminal A=11.5 mm, B=6 mm A=11.5 mm, B=6 mm Solid and flexible Solid and flexible Wire cross section : Wire cross section : H05VV-F 2x1,5 mm2 H03VV-F2x0,50 mm2 Cable Clamp Reference Cable Jacket Diameter: Round: max 7mm Earth Connection • OT 50/24 is a “Protection Class II” power supply, therefore ground connection is not required Mounting and Environmental protection • • The control gear is an independent type for luminaire integration Maximum permissible ambient temperature must not be exceeded. Make sure there is adequate space to avoid a build-up of heat. In critical installations the temperature at tc has to be controlled. Cfr drawing below: Bottom view 2 General Note • • • Power supplies must be installed by a qualified electrician Disconnected from mains supplies before wiring work For further information see also “OPTOTRONIC – Technical guide” at www.osram.com OSRAM AG www.osram.com 2012-12-12 AA420880055 Steinerne Furt 62, 86167 Augsburg, Germany No. 1, North Industrial Road 528000 Foshan Guangdong, P.R.
