Providing outstanding performance and reliability, the Powerware 9355 UPS’s unique
benefits including the following:
S Online UPS design with pure sine wave output. The UPS filters and regulates
incoming AC power and provides consistent power to your equipment without
draining the battery.
S More wattage in less space with a 0.9 power factor — protecting more equipment
and leaving more room for expansion.
S A UPS maintenance bypass switch (MBS) that provides a Make-Before-Break
(MBB) wrap-around bypass for UPS maintenance or service without shutting down
the load.
S Support for Powerware Hot Sync
®
paralleling of multiple modules for redundancy
or extra capacity.
S Input current total harmonic distortion (THD) of less than five percent, using active
input power factor correction.
S ABM
®
technology that uses advanced battery management to increase battery
service life, optimize recharge time, and provide a warning before the end of useful
battery life.
S Over two hours of extended runtime with added EBCs.
S Advanced power management with the Software Suite CD for graceful shutdowns
and power monitoring.
S Emergency shutdown control through the remote emergency power-off (REPO)
port.
S Start-on-battery capability for powering up the UPS even if utility power is not
available.
S Standard communication options with a DB-9 serial port, relay output contacts, and
programmable signal inputs.
S Optional X-Slott cards with enhanced communication capabilities for increased
power protection and control.

operation from a 208V, 480V, or 600V 60-Hz source (input transformer in
single-feed systems or bypass transformer in dual -feed systems)
- Options Cabinet for dual-feed systems that provides the second input from a
208V, 480V, or 600V 60-Hz source
- Options Cabinet with an output isolation transformer for 480V loads
S Wall-Mounted Bypass Switch
The optional wall-mounted bypass switch is used to bypass the UPS during
maintenance or servicing, providing wrap-around bypass for UPS service without
