2.3 Customer-supplied Items
•On-chip debug emulator with programming function MINICUBE2
•LED load
Supply LED loads with the following specifications.
Voltage: 50 [V] or less per channel
Current: 400 [mA] or less per channel
Caution Depending on the characteristics of the load, input voltage, and program algorithm, intended
output characteristics may not be obtained even within the ratings above. When a program
created with the auto generation tool Applilet EZ for HCD is used, dimming operation of the
main unit may stop due to overvoltage or overcurrent. If intended output characteristics
cannot be obtained or if dimming operation stops in the program created with Applilet EZ for
HCD, review the characteristics of the load, input voltage, and program algorithm, etc.
•LED load connection cable
Use a cable that can withstand the voltage and current applied to the LED load used.
•Lighting communication master evaluation board (EZ-0008)
It is required for evaluation of the DALI communication/DMX512 communication.
Use AC power supply in the range of 100 VAC to 240 VAC.
Using AC power supply out of this range may cause product failure, generation of heat, fire or electric
shock.
When connecting the LED load to this product, the user must be responsible for performing
work and connection of wiring properly to avoid defective connection.
Improper wiring work or connection may cause failure, heat generation, fire, or electric shock.
Use wires that have the ratings of the LED load complying with the safety standard or better to
connect the LED load.
Using nonconforming items or items that do not satisfy the ratings may cause failure, heat generation,
fire, or electric shock.
For the circuit diagram of the EZ-0011, refer to APPENDIX A CIRCUIT DIAGRAM.
