Summary Alarm Contacts
Alarm contacts are provided for connection to equipment at your facility, such as a
light, an audible alarm, or a computer terminal. The equipment you connect to these
contacts alerts you to an UPS alarm. This feature is described further in Chapter 10,
“Using Features and Options.”
7.3.2 Advanced Battery Management
A three stage charging system increases battery service life by optimizing recharge
time, and protects batteries from damage due to high current charging and inverter
ripple currents. Charging at high currents can overheat and damage batteries.
7.3.3 High Efficiency Mode
A High Efficiency Mode is available that allows the UPS to operate in an offline
bypass mode. In this mode, the UPS is operating on bypass, with the power
processing unit in standby, ready to automatically transfer to normal mode if a
commercial electrical power brownout, blackout, overvoltage, undervoltage, or
out-of-tolerance frequency condition occurs.
7.3.4 Customer Convenience Outlet
An uninterruptible 120VAC, 0.2 amp, fuse-protected convenience outlet is provided
to supply power to the optional modem. It is located on the Customer Interface
Panel.
7.3.5 Installation Features
Power wiring can be routed through the rear and bottom of each cabinet with
connections made to easily accessible terminal blocks. External sensing
and monitoring control wire must be installed in accordance with Class 1 wiring
methods. Class 1 wiring can be routed through the top of each cabinet.
Communications option cards are quickly installed through the rear panel. X---Slot
cards are hot pluggable.
