System Reset
The UPS is reset by moving the RUN/STOP switch from RUN to
STOP and then back to RUN. Use this reset procedure to transfer
from bypass back to inverter after a fault occurs. Some faults can
only be cleared by shutting the UPS down, waiting for all LED's to go
off, and then restarting the UPS (see "Troubleshooting", page 22).
Battery Backup Time
The exact amount of backup time provided will vary depending on
the UPS model being used, number of batteries, condition of the
batteries and other factors. However, the chart below gives the
times that can be expected from the standard units with batteries in
good condition. For greater backup time, an additional battery
module may be added to the standard unit. Only one additional
battery module may be added to the standard unit. For longer
runtime options contact your Toshiba sales representative or the
Toshiba marketing department at (800) 231-1412 or by e-mail at
toshibaups@tic.toshiba.com.

* Times given are approximate and will vary depending on the age of the batteries, the
ambient temperature, the number of previous discharges and the type of load.
Load Shed Function
The 1700 Series includes a load shed function. During battery
backup operation, this function allows the load connected to two of
the receptacles (figure 1, page 9) to be turned off in an effort to
conserve power for more critical loads. The battery level at which
these receptacles will be turned off, or "shed", can be set by the user
(see "The Function Control Button", page 17). By default, this
feature is configured so that the receptacles will remain on for the full
battery backup time available (no "shedding")
Battery Recharge Time
The following table gives estimates on time required to recharge the
UPS's batteries. The recharge time may vary depending on the
ambient temperature, the age of the batteries, and other factors.
