Caution
Do not mix hazardous voltage circuits and human-accessible
circuits on the same module.
Caution
Ensure that devices and circuits connected to the module are
properly insulated from human contact.
Caution
When module terminals are hazardous voltage LIVE (>42.4 V
pk
/60
V DC), you must ensure that devices and circuits connected to the module
are properly insulated from human contact.
