Note
The 0-V terminals of X4 and X5 of the PLD 16-8 are connected internally. These connections
are used for connecting the potential of the electronics and for operating the LEDs. Since
only a low current is required (max. 50 mA), it is sufficient to establish only one 0-V
connection (preferably at X4).
