Determining Your Type of
Input Power Before you wire your Ultra1500 system you must determine the type of input
power you are connecting to. The Ultra1500 is designed to operate only in
grounded environments.
Grounded Power Configuration
The grounded power configuration allows you to ground your single-phase or
three-phase power at a neutral point. Match your secondary to one of the
examples below and be certain to include the grounded neutral connection.
