Ensure proper insulation of not connected wire terminals.
2 Output channels for optional splitting of the load (1 channel use also possible when the not used cable is open)
Ensure that the complete Load is not connected to one channel. Maximum output current is limited by the cross section of the cable
(7.5A per channel – 90 Watt) a). It is possible to join the two output cables together, in parallel, to drive one module at max power.

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.
Not used output cables have to be insulated separately
Earth Connection


Protective earth connection of OT 120/12 P is mandatory for safety and EMI reasons
The ground connection has to be done via the input cable
Mounting and Environmental protection


The control gear is a built 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
General Note



Power supplies must be installed by a qualified electrician
Disconnected from mains supplies before wiring work
