Caution
Do not connect the piezo unit to a 'live' external power supply. Doing so (i.e. "hot
plugging") carries the risk of PERMANENT damage to the unit. Always ensure
the power supply unit is isolated from the mains and the front panel switch turn
OFF before connecting to the piezo unit.
Always power up the piezo unit by connecting its power supply to the mains
then switch ON using the front panel switch. Similarly, to power down the unit,
turn the front panel switch OFF, then disconnect the power supply from the
mains before disconnecting the piezo unit.
Caution
To avoid overheating the unit, do not turn off the power until both fans have
stopped.
