OPTOTRONIC®
OT 120/220-240/24 P
Constant Voltage LED Power supply for 24V LED - Modules
The installation of two ore more OPTOTRONIC® OT 120/220-240/24 P Power supplies with common “-“ or “+” wiring is forbidden.
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
Please avoid direct exposure of sunlight and in case of exposure to UV rays, protect the cables with
suitable silicone sheath.
Earth Connection
•
•
Protective earth connection of OT 120/24 P is mandatory for safety and EMI reasons
The ground connection has to be done with the input cable
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
General Note
•
•
•
Power supplies must be installed by a qualified electrician
Disconnected from mains supplies before wiring work
