4 INSTALLATION AND START-UP
This section contains information and warnings that the user must respect at all times to guarantee
his/her own safety and the safe operation of the unit.
WARNING! The Computer MAX 6f V12dc regulators are connected to units with capacitors
that remain charged even after the voltage has been disconnected. Wait at least 5 minutes
after the unit has been disconnection, before the internal components of the equipment are
handled, in order to avoid the risk of electric shock.
Handling or use of the unit other than that specified by the manufacturer may
compromise user safety.
The power supply must be disconnected from the unit when it shows signs of deterioration or faulty
operation. In this case, contact a qualified service representative.
The persons responsible for the installation or operation of the computer MAX 6f 12 Vdc regulator must
follow common electrical installation safety measures for LV or MV installations to guarantee a safe
operation, depending on the installation location. In addition, they must take into account all warnings
found in this instruction manual.
