The alert message can be removed only when the system
has returned to work correctly from the mains (as required
by the EN50171 standard). To remove the alert message,
press the ON key.

The CPS in case of a permanent failure will be not able to supply the load. To ensure total protection of your
equipment we suggest you install an ATS device (Automatic Transfer Switch) or an external automatic by-
pass. For more information visit
