Chassis-Mounted Battery Isolator

A chassis-mounted battery isolator is a heavy-duty switch used to disconnect a vehicle’s electrical system from its battery supply. It improves safety during maintenance, reduces fire risk, and prevents battery drain during storage.

When activated, it breaks the electrical circuit so power cannot reach vehicle systems. This supports electrical isolation during maintenance before work begins on electrical or mechanical components.

Isolation practice is relevant across fleets including road sweepers with operator, and site teams may keep procedures and checklists in downloads and resources.
