This whitepaper covers the proper method used to disconnect power quality recorders and remove them safely from their location. Following the proper disconnection sequence eliminates or minimizes generating and recording false events as the leads are disconnected. Also, the proper disconnection process prevents the recorder from running on the ride-thru battery after it’s removed from the circuit. The ideal disconnection process is described below for PMI recorders with and without a display, and with and without local communications.

This white paper includes:

• Disconnect sequence: recorder with a display
• Disconnect sequence: units without a built-in display
• Disconnect sequence: alternate method
