3.
Wire and Connection
Ensure that the LED module load is within the range of rated voltage, current and power supply (see
Technical data)
The luminaries’ manufacturer is responsible for providing the required clearance and creepage distances
and also for the protection against electrical shock, especially for the line and load wires.
Wiring Preparation:
4. Earth Connection
OTe 18/220-240/500 PC is a “Protection Class II” power supply, therefore ground connection is not
required
5. Mounting and Environmental protection
The control gear is a built in type for luminaire integration; an optional cable clamp is available for
independent installation; proper cables should be used.
Maximum permissible ambient temperature must not be exceeded. Make sure there is adequate space to
avoid heat build-up. In critical installations, the temperature at tc point should not exceed the declared
value.
6.
General note
Power supplies must be installed by qualified electrician
Disconnected from mains supply before wiring work
Hot plug-in or secondary switching of LEDs is not permitted, as it may cause a very high transient current
to the LEDs
For further information, please refer to “OPTOTRONIC -Technical guide” at www.osram.com
Proper and safety usage and installation of the product shall comply with product
datasheet and OPTOTRONIC Technical guide. The latest documents are
available at www.osram.com
