Safety
■ THE M97 DOES NOT COMPLY WITH THE
REQUIREMENTS OF THE EN60950
STANDARD. THE MAXIMUM INPUT
VOLTAGES ARE 60V DC AND 42V AC.
HOWEVER, THE M97 WAS DESIGNED TO
PROVIDE HIGH-VOLTAGE FUNCTIONALITY.
IF YOU NEED TO APPLY VOLTAGES
HIGHER THAN 60V DC AND 42V AC, TAKE
APPROPRIATE MEASURES TO KEEP THE
SAFETY REQUIREMENTS OF EN60950.
