Chapter 1 Introduction
The Eaton ® Powerware ® 9390 UPS Sidecar is designed for use with the Powerware
9390 80 kVA 208/208V and 480/480V and 160 kVA 480/480V three-phase
uninterruptible power systems (UPSs). The UPS Sidecar provides maintenance
bypass or tie cabinet functions with the following custom configurable features,
enabling adaptation and expansion without costly electrical rework:
S Maintenance Bypass Configuration – Maintenance Bypass (MBP) and Maintenance
Isolation (MIS) breakers enable power to completely bypass the UPS power
module. The UPS module can then be safely serviced or replaced, without
interrupting power to critical systems. An optional Bypass Input Breaker (BIB) and
Rectifier Input Breaker (RIB) provide a single wiring point input to the UPS and a
convenient method for removing power from the UPS when using the
maintenance bypass to supply the load.
S Parallel Redundant Configuration – Module Output Breakers (MOBs) 1 and 2
enable two UPS modules to be paralleled together for redundancy. An optional
System Load Breaker (SLB) provides output control to the critical load for the
whole system.
The UPS Sidecar is attached to and directly integrated with the UPS cabinet and has
safety shields behind the removable front panel for hazardous voltage protection. The
UPS Sidecar matches the UPS cabinet in style and color. Figure 1-1 shows the
Powerware 9390 UPS (40–80 kVA) with the UPS Sidecar and Figure 1-2 shows the
