RECmax Lpd
6.- CONFIGURATION
The correct operation of the
RECmax Lpd
depends on its correct adjustment. Since
it is a protection device, erroneous adjustment can compromise the protection of
property and people. That is why it is very important that it is adjusted by a trained
technician to decide on the most appropriate type of protection in each installa-
tion.
CIRCUTOR
accepts no responsibility for incorrect working of the device due to
erroneous adjustment
