7 Disassembling the Inline Fuse Connectors
Danger to life due to electric arc
An electric arc may occur when plugging or removing the DC connectors or the inline fuse
connectors under load and in case of a reverse-poled connection of the DC connectors. Electric
arcs can result in death or serious injury.
• Ensure the correct polarity of the strings before connection.
• Plug or remove DC connectors and inline fuse connectors only under load-free conditions.
• Disconnect the DC sub-distribution (see the DC sub-distribution manual).
• Wear suitable personal protective equipment.
Risk of burns due to hot inline fuse connectors
During operation, the temperature of the inline fuse connectors can reach up to 90°C. Touching
the inline fuse connectors can result in burns.
• Only touch the inline fuse connectors wearing suitable personal protective equipment.
• Position hot, removed inline fuse connectors in such a way that they cannot be touched
inadvertently.
• Mount the inline fuse connectors in such a way that air can circulate around them. Cooling
the inline fuse connectors by the ambient air is absolutely necessary.
• Mount the inline fuse connectors in such a way that they cannot be touched inadvertently.
Ensure that air circulation around the inline fuse connectors is not prevented.
Procedure:
1. Disconnect the DC sub-distribution (see the DC sub-distribution manual).
2. Insert a screwdriver or an angled screwdriver
(blade width: 3.5 mm) into one of the side slots
of the DC connector and pull the inline fuse
connector straight out. Do not pull on the string
cables.
