Manual Overview
This page hosts the ASCO 962 ATS Bypass-Isolation Switches Operator’s Manual, covering control panel operation, transfer switch functions, and bypass-isolation procedures. The manual is provided as a free, verified PDF download for operators and maintenance personnel working with ASCO 962 series ATS units.
Voltage and frequency settings are adjusted through incremental DIP switches on the panel, matched against a labeled template on the control panel cover. The panel also supports the unit’s bypass-isolation function, allowing maintenance to be carried out without interrupting load power to connected equipment.
