PROTECTIONS
– Mains supply fuse – Mains supply fuse – Mains supply fuse
– Charging inhibition due to: – Charging inhibition due to: (5, 6, 10, 12A types only)
• short circuit at battery terminals • short circuit at battery terminals – Battery output fuse
• battery polarity inverted • battery polarity inverted – Charging inhibition due to:
• low voltage at battery poles (<0.5 Ue) • low voltage at battery poles (<0.5 Ue) • short circuit at battery terminals
• battery polarity inverted
• low voltage at battery poles (<0.5 Ue)
• disconnected battery
