2.4.5 SAFETY
When the system is connected, it may be dangerous to touch the terminals.
Additionally, dangerous parts may be exposed when covers are opened or
when protective components are removed. The system should not be used
until it is completely installed.
To increase system capacity with expansion cards prior to handling, modify
its connections or replace equipment; the power supply should be shut off
and the inputs disconnected from the CVMk2. Handling the system while it
is powered up is dangerous.
