DANGER!
Electric shock
There are live parts on the circuit boards. If
touched, they can cause injury and
property damage.
Before beginning any work, isolate the system
completely from all power sources, ensure that it
cannot be switched back on, and verify that it is
safely isolated from supply.
DANGER!
Do not carry out work on high voltage units
The housing of the high voltage unit may
not be opened or damaged as there are
parts inside it that are under high voltage.
Non-compliance with the above may
result in serious or fatal injuries.
