1.6 PERFORMANCE DESCRIPTION
A. Automatic operation includes the following:
1. Normal Conditions: Supply the load with ac power flowing from the normal ac
power input terminals, through the rectifier -charger and inverter, with the battery
connected in parallel with the rectifier -charger output.
2. Abnormal Supply Conditions: If normal ac supply deviates from specified and
adjustable voltage, voltage waveform, or frequency limits, the battery supplies
energy to maintain constant, regulated inverter ac power output to the load
without switching or disturbance.
3. If normal power fails, energy supplied by the battery through the inverter
continues supply -regulated ac power to the load without switching or disturbance.
4. When_ power is restored at the normal supply terminals of the system, controls
automatically synchronize the inverter with the external source before
transferring the load. The rectifier -charger then supplies power to the load
through the inverter and simultaneously recharges the battery.
5. If the battery becomes discharged and normal supply is available, the rectifier -
charger charges the battery. On reaching full charge, the rectifier -charger
automatically shifts to float -charge mode.
6. If any element of the UPS system fails and power is available at the normal
supply terminals of the system, the static bypass transfer switch switches the
load to the normal ac supply circuit without disturbance or interruption.
7. If a fault occurs in the system supplied by the UPS, and current flows in excess
of the overload rating of the UPS system, the static bypass transfer switch
operates to bypass the fault current to the normal ac supply circuit for fault
clearing.
8. When the fault has cleared, the static bypass transfer switch returns the load to
the UPS system.
9. If the battery is disconnected, the UPS continues to supply power to the load with
no degradation of its regulation of voltage and frequency of the output bus.
B. Manual operation includes the following:
1. Turning the inverter off causes the static bypass transfer switch to transfer the
load directly to the normal ac supply circuit without disturbance or interruption.
2. Turning the inverter on causes the static bypass transfer switch to transfer the
load to the inverter.
1.7 SERVICE CONDITIONS
A. Environmental Conditions: The UPS shall be capable of operating continuously in the
following environmental conditions without mechanical or electrical damage or
degradation of operating capability, except battery performance.
1. Ambient Temperature for Electronic Components: 32 to 104 deg F (0 to 40
deg C).
2. Ambient Temperature for Battery: 41 to 95 deg F (5 to 35 deg C).
3. Relative Humidity: 5 to 95 percent, noncondensing.

component under any condition of normal operation.
E. Selecting first option in first paragraph below may make it easier to provide good, well -

G. Maximum AC Output -Voltage Regulation for Loads up to 50 Percent Unbalanced: Plus
or minus 2 percent over the full range of battery voltage.

circuits shall limit THD to 3 percent, maximum, at rated full UPS load current, for
power sources with X/R ratio between 2 and 30.
