IEC
Use two (2X) 20 mm Slow-Blow fuses for line and neutral fusing – fuses are contained
within a fuse holder that is press-fit into the body of the IEC power module:
•
Use 5.0A fuses for 115 volt AC operation
•
Use 2.5A fuses for 230 volt AC operation
This optional connector supplies the 24V or 48V Direct Current (DC)
power to the CDM-570 or CDM-570L units.
