American Power Conversion MatrixTM UPS - Manual (Page 34)

8.0 Storing the UPS
8.1 Storage Conditions
The UPS should be covered and stored in a cool dry location. The UPS should be stored with the Battery Packs in a
fully charged state. That is, the reported battery capacity should be at 100% before the UPS is switched off for storage.
Disconnect the Battery Packs from the UPS and from each other (where applicable). Store the Battery Packs in an
upright position.
8.2 Extended Storage
To achieve expected run time following extended storage, the UPS should be allowed to refresh the Battery Packs every
6 months in environments where the ambient temperature is -15°C to +30°C (5°F to 86°F). For extended storage in
environments where the ambient temperature is +30°C to +45°C (86°F to 113°F), the UPS should be allowed to refresh
the Battery Packs every 3 months.
9.0 Specifications
Note: Where specification ratings differ, values for the UPS configured for 240 Vac operation are given in brackets [ ].
9.1 Input
Nominal input voltage: single phase 208 Vac [240 Vac].
Nominal input frequency: 60 Hz.
On-line efficiency @ full load: > 92%, > 93% with fully charged batteries for the 3000VA and
5000VA models, respectively.
Input circuit breaker: 20 Amp, 30 Amp; for the 3000VA and 5000VA models, respectively.
Input connector: NEMA L6-30P (250V/30A).
9.2 Transfer Characteristics
Frequency limits for on-line operation: 60 Hz, ±5%.
Input voltage limits for on-line operation: -25% to +15% of the nominal input voltage.
Transfer to/from on-battery: 0 ms typical with computer loads, 1.5 ms maximum. Transfer occurs
synchronous with the utility voltage phase.
Transfer to/from bypass: Transfers to and from bypass occur synchronously with the utility voltage
phase. Transfers both to and from bypass mode occur in 0 mS typically.
9.3 Output Characteristics
Maximum load: 3000 VA or 2250 W @ 0.75 power factor; 4700 VA or 3750 W @ 0.8 power factor
[5000 VA, 3750 W @ 0.75 power factor] for the 3000VA and 5000VA models, respectively.
Nominal output voltages: 208 Vac / 120 Vac [240 Vac / 120 Vac].
On-line voltage regulation: ±5%. When "Auto" or "Low" utility failure sensitivity is selected by the
user, the output voltage regulation may become relaxed to +5%, -12%.
On-line frequency regulation: 60 Hz, ±5% (synchronized to the utility).
On-battery output voltage regulation: ±5%.
On-battery output frequency regulation: 60 Hz, ±0.1 Hz unless synchronized to utility frequency
during utility brownout.
On-battery output voltage total harmonic distortion: < 5%.
