Chapter 4 UPS Sidecar Features, Controls, and Operation
4.1 UPS Sidecar Standard Features
The UPS Sidecar has many standard features that provide cost-effective and
consistently reliable power distribution. The descriptions provide a brief overview of
the UPS Sidecar controls, and standard and optional features.
4.1.1 Maintenance Bypass Configuration
A Maintenance Bypass switch (MBP), in combination with the Maintenance Isolation
switch (MIS), can be used to completely isolate the UPS during service. The UPS can
be serviced or replaced without interrupting power to critical systems.
4.1.2 Parallel Redundant Configuration
Module Output Breakers 1 and 2 enable two UPS modules to be paralleled together
for redundancy. An optional System Load Breaker provides output control to the
critical load for the whole system.
4.1.3 Customer Interface
The UPS Sidecar uses one UPS building alarm input for Maintenance Bypass Switch
Monitoring. The building alarm is used to detect when the Maintenance Bypass
switch is closed and the system is on bypass.
4.1.4 Installation Features
The UPS Sidecar is factory-installed to the side of the UPS cabinet. Power wiring can
be routed through the top or bottom of the cabinet with connections made to easily
accessible terminals. Parallel redundant modules can be installed in line-up-and-match
or standalone configurations. Line-up-and-match cabinets are wired through the side
panels of the units.
4.1.5 Expansion
The UPS Sidecar supports custom configurations and scalability to adapt to changing
and future power and distribution needs. See paragraph 4.2 for available options.
4.2 Options
Contact your sales representative for information about any of these available options:
4.2.1 Bypass Input Breaker (BIB)
Maintenance bypass configurations have an optional BIB for single-feed and dual-feed
systems. The BIB provides a single point of input power control to the UPS and easily
removes power from the UPS for servicing.
