overload (ca. 4 minutes) or short circuits.
The device must then be replaced.
• The AC 24 V side does not have protection against faulty wiring on
AC 230 V.
• AC 230 V mains power for supply and relay must be switched off prior to
plugging in and removing plug-in terminals (risk of electric shock!)
• Supply circuits are interrupted as soon as plug 19/21 is removed from the
device. (Bridges 19-19 and 21-21 are located on the print, not the plug; see
