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

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

2 General Note
•
•
•
Power supplies must be installed by a qualified electrician
Disconnected from mains supplies before wiring work
