CAUTION:
MOST PARTS OF THE CIRCUIT CARRY DANGEROUS VOLTAGES (MAINS) !
OBSERVE ALL SAFETY REQUIREMENTS THAT MIGHT APPLY !
MOUNT THIS KIT PREFERABLY IN AN ISOLATING HOUSING.
Check the optical isolation between the mains voltage terminals (SK1 and SK2) and the DMX connecter
terminals (SK4) by means of a multimeter (fig 2.0). Resistance should be infinite.
Make sure you mount the appropriate fuses: F1 (5A) protects the outputs against overload but not against
short circuits! A short circuit will damage the TR1 triac. F2 (100mA) protects the electronic parts on the
circuit.
Never install higher value fuse !
