The following sequence should be used:
1. From the PowerView display, go to "Control" / "UPS into Bypass" and press "Return".
2. Answer "Yes".
3. Engage the Maintenance Bypass Switch. (Do Not Open the Input Breaker, the critical load will be dropped if the Input Breaker is opened).
4. Now the unit is in Maintenance Bypass. While in this state, tasks such as removing both intelligence modules or cycling the System Enable switch can be done.
Caution: There is still power present inside the Symmetra frame. Only the Power, Intelligence, and Battery Modules can be safely removed / replaced. If work is to be performed inside the frame, it needs to be done by APC's Field Service Engineers when the UPS is fully powered down.
