2. Important Safety Warnings
When installing the unit, verify that any maintenance bypass panel used is configured correctly before applying power to the unit.
• Be sure to place a warning label on all primary power isolators installed remotely from the UPS area and on any external access points
between such isolators and the UPS. The warning label shall carry the following wording or equivalent.
