PROBLEM

Show/hide table

The existing breaker labels may have been installed in the wrong positions on certain UPS 500G, and UPS 600G UPS Uninterruptible Power Supplies equipped with the Utility Maintenance Bypass (UMB) option. If the existing location of the breaker labels is incorrect, it could lead to improper operation of the system when going to Maintenance Bypass and cause the customer load to be dropped.
