3.4.1
Battery backup protection is provided by equipping the UPS system with up to 4
external battery cabinets (EBCs) containing sealed lead-acid, maintenance-free
batteries. An EBC is a single, free-standing cabinet designed to be installed as a
part of a UPS system, but may be installed separate from the UPS cabinet.
3.4.2
A tie cabinet provides the ability to parallel up to 4 UPSs together for increased
capacity and/or redundant capability and may also include a system bypass
switch. The tie cabinet is a free-standing cabinet designed to be installed
separate from the UPS cabinet.
3.4.3
A parallel UPS system with up to 4 UPSs can be installed to provide a parallel
capacity and/or N+1 redundant system. This load sharing system provides more
capacity than a single UPS, and can provide backup, depending on the load and
configuration. In addition, when one UPS is taken out of service for maintenance
or is not operating properly, a redundant UPS continues to supply uninterrupted
power to the critical load. A controller area network (CAN) bridge provides
connectivity for system metering and operational mode control. The parallel
system consists of 2 to 4 UPSs each with a parallel CAN bridge, and a tie
cabinet or system parallel module to act as a tie point and to control the output.
The tie cabinet must contain module output breakers (MOBs) for each parallel
UPS with dual auxiliary contacts for the control of the system. Without dual
auxiliary MOBs, UPSs are not allowed to go to bypass individually during
servicing. All UPSs will go to bypass instead of just the UPS needing service,
decreasing critical load protection. With dual auxiliary MOBs, one UPS can be
bypassed while the remaining UPSs support the load as long as the remaining
UPMs have the capacity to do so. The MOBs must disconnect all 3 phases and
neutral.
