Fixed Frequency Mode
The 1700 Series UPS has the option of operating in a fixed
frequency mode. Normally the UPS operates in the frequency auto-
detect mode. If a specific output frequency is required (i.e. 50Hz or
60Hz) the UPS can be set at the factory to supply the desired
frequency regardless of the input frequency (input frequency must be
within allowable limits, see Specifications on page 31). For a unit
already in use the output frequency can be set through software. For
instructions on setting the output frequency through software please
contact Toshiba at [phone] or by e-mail at
[e-mail]. It is important to note that when the
UPS is operating with a fixed output frequency, output is
disabled in bypass.
Adding an Additional Battery Module
Note: 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 [e-mail]. Figure 5 shows
the standard unit with one additional battery module added. To
install a second battery module follow these steps:
1) Unplug the standard battery module from the electronics module.
Unlock and remove the
electronics module from the
battery module.
2) Lock the two battery
modules together. Plug the
bottom battery module into the
top battery module.
3) Lock the electronics
module on to the top battery
module. Plug the battery
module into the electronics
module.
It is not necessary to stack the
modules for the system to
operate. Refer to the section
entitled “UPS Connections:
Standard Module Connections”
on page 10 for an explanation
of how to lock and unlock the
modules.
