These Kohler automatic transfer switches sit between your utility power and generator, usually in plant rooms, data centers, pump stations, or commercial buildings, and their whole job is to move the load cleanly when the mains drop. This manual is what I’d keep on hand when installing, setting up, or diagnosing these ATS units so the power changeover stays smooth and predictable. For example, if the switch hesitates or chatters when the utility comes back, I’d use this document to verify wiring, check control settings, and confirm the operating sequence before swapping parts.
Applications & Use Cases
FAQ
Q: Can I keep this manual on a tablet or phone at the jobsite?
A: Yes, it’s convenient to use digitally so you can zoom in on diagrams and search terms while you’re in front of the switch.
Q: Should I still print a copy for the equipment room?
A: It’s a good idea; a clean printed copy in a sleeve near the ATS helps during outages when network access isn’t guaranteed.
Safety Note
Always de-energize and lock out all power sources before opening or working inside the transfer switch.
