American Power Conversion MatrixTM UPS user manual

For applications where the UPS is used as a remote power source or where the UPS frequently transfers to on-battery operation due to poor service quality, the function of the audible alarm may be altered so that it will not become an annoyance.

λAll imed - A sequence of four beeps is sounded immediately upon transfer to on-battery operation. The UPS sounds the beep sequence every 30 seconds while operating on-battery. When low battery conditions are reached, the alarm changes to a beep once every second.

λ30s delay - The on-battery audible alarm is disabled for the first 30 seconds of on-battery operation.

λLow Batt - The audible alarm is disabled during on-battery operation until low battery conditions are reached.

λDisable - The audible alarm is disabled during on-battery operation and

low battery conditions.

Many computer networks that issue UPS shutdown commands are unable to do so as the last part of a shutdown routine. For these applications, the UPS provides a settable delay interval before shut down to allow the network to finish its shutdown routine.

λShut down delay function choices are 20, 180, 300, and 600 seconds.

A delay interval before energizing the output following return of normal utility voltage, or following a scheduled shut down, may be set by the user. This delay is useful in applications that require staggered power up of equipment connected at various sources.

λLoad power delay function choices are 0, 60, 180, and 300 seconds.

This function has no meaning for the 208/240 Vac, 60 Hz version UPS. The display will always respond 208 V.

The UPS can be set to report the output voltage from either the nominal 208V or 240V output. This can be accomplished regardless of whether the input is configured for operation from 208V or 240V service. When an optional power distribution plate or Power Distribution Unit (PDU) is installed, the UPS should be set to report the correct output voltage. When the Auto function is chosen, the reported nominal output voltage is scaled according to the input tap selected (see section 4.5).

The UPS can be set do display all menu choices in either English, French, German, or Spanish.
