be switched on for proper UPS operation.
2 Battery Connector
The battery connector connects the external batteries to the Alpha Micro.
3 Internal Fan
This microprocessor-controlled fan regulates the Alpha Micro’s internal temperature for optimum performance. It
must not be blocked. If the fan fails, an alarm is generated.
