China OPTOTRONIC® OTe 120/110-277/12 E Constant Voltage LED Power supply for 12 V LED - Modules The installation of two or more OPTOTRONIC® OTe 120/110-277/12 E Power supplies with common “-“ or “+” wiring is forbidden. 4 Wiring and Connection • • • • • Ensure that the LED module load is within the range of rated voltage, current and power (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 Please avoid direct exposure of sunlight and in case of exposure to UV rays, protect the cables with suitable silicone sheath 5 Earth Connection • • Protective earth connection of OTe 120/110-277/12 E is mandatory for safety and EMC reasons The ground connection has to be done via the housing case and proper countersunk screws should be used 6 Mounting and Environmental protection • • The control gear is a build in 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 7 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 Steinerne Furt 62, 86167 Augsburg, Germany 2013-07-31 AA3980300DG AA3980301DG No. 1, North Industrial Road 528000 Foshan Guangdong, P.R.
