Installation
CAUTION!
Static charges can damage the electronic components of the

There are no directly accessible circuits operating under dangerous voltage on
Forum 523/524’s connection panel. You must still switch off all power to the
device when performing any kind of installation. Pull the plug out of the

It is recommend to connect the pressure terminals provided here as sockets to
externally mounted sockets – e.g. UAE sockets for U

connecting sockets into terminals and do not have to switch off the device to
do this.
