AC Mains Connector
The AC Mains Connector is located at the rear of the top case, on the back
wall. It is part of one assembly with the ECG Out (Sync) connector.
Preparation
1. Save the configuration.
If possible, save the customer’s configuration onto a Data Card (or print
the configuration) so the configuration can be restored after the repair is
complete.
2. Open the case safely.
See "Opening the Case" on page 4-24.
