Figure 6: Power supply on the DC basic units
Applies to EZ-AC devices with a power supply greater
than 24 V AC:
• The voltage terminals for phase L and neutral conductor
N have been reversed.
• This enables the EZ interface (for memory card or PC
connection) to have the full connection voltage of the
phase conductor (100 to 240 V AC).
• There is a danger of electric shock if the connection at the
EZ interface is not properly connected or if conductive
objects are inserted into the socket.
Attention!
A short current surge will be produced when switching on
for the first time. Do not switch on EZ by means of reed
contacts since these may burn or melt.
