These are contained within the body of the connector, behind a small plastic flap.
• For 230 volt AC operation, use T0.75A, (slow-blow) 20mm fuses.
• For 115 volt AC operation, use T1.25A, (slow-blow) 20mm fuses.
IMPORTANT
For continued operator safety, always replace the fuses with the correct
type and rating.
