• When wiring AC supplies the "Live" cable should be connected to the "L" terminal and
the "Neutral" cable should be connected to the "N" terminal. Do NOT connect the "Live"
wire to the "N" terminal, the user might receive a dangerous shock on powerup.
• When wiring DC supplies the "positive" cable should be connected to the "+" terminal
and the negative cable should be connected to the "-" terminal. On no account should
the power supply terminals be connected to any other terminal on the unit. DC Power
