l
The isolation between the channel and chassis is classified as
REINFORCED . This can be seen as double isolation, which is necessary
because the chassis might be accessible (conductive parts can be touched)
to users (personal safety).
l
Isolation between channels is BASIC , since a channel is not accessible.
Therefore, there is no direct risk to users (product safety).
l
REINFORCED or DOUBLE isolation has higher test values than BASIC
isolation.
