Applies to CL-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 CL interface (for memory module or
PC connection) to have the full connection voltage of
the phase conductor L (100 to 240 V AC).
• There is a danger of electric shock if the CL 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 the logic relay with reed
contacts because these could possibly burn or stick.
