iii. Single control of more power supplies
Control of more OT 80/220-240/24 DIM P to an external Dimmer/Potentiometer. Thanks to the fully isolated 1…10V interface, two different kind of
dimming devices are possible

The maximum input capacitance of all connected LED modules (dimmable) should be less the 130nF.
3. Safety
Power supplies can be connected in parallel on the primary side, but not on the secondary side

a)
The installation of two ore more OPTOTRONIC® OT 80/220-240/24 DIM P Power supplies with common “-“ or “+” 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.
Not used output cables have to be insulated separately
Earth Connection
•
OT 80/24 P is a “Protection Class II” power supply, therefore ground connection is not required
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
