  • Page 60: Understanding Ups Operation

    6 Understanding UPS operation 6.1 Looking inside the UPS system The Eaton 9395 UPS is a continuous-duty, solid-state, transformerless (at 400 Vac), three-phase, true online system that provides conditioned and uninterruptible AC power to the UPS system’s output and critical load. The basic system consists of a rectifier, battery converter, inverter, monitoring/operation control panel, integrated communication server, and digital signal processor (DSP) logic.

  • Page 61: Single Ups

    UPS to successfully support its applied loads. 6.2.1 Modes The Eaton 9395 UPS supports a critical load in five different modes of operation. The UPS can automatically use all five modes, as required. NOTE The Variable Module Management System and Energy Saver System modes are mutually exclusive.

  • Page 62: Figure 6-2. Path Of Current Through The Ups In Normal Mode

    Figure 6-2. Path of current through the UPS in normal mode During normal UPS operation, power for the system is derived from a utility input source through the rectifier input contactor K1. The front panel displays Normal, indicating the incoming power is within voltage and frequency acceptance windows.

  • Page 63: Bypass Mode

    6.2.3 Bypass mode The UPS automatically switches to bypass mode if it detects an overload, load fault, or internal failure. The bypass source supplies the commercial AC power to the load directly. Figure 6-3 shows the path of electrical power through the UPS system when operating in Bypass mode. CAUTION The critical load is not protected while the UPS is in Bypass mode.

  • Page 64: Variable Module Management System

    6.2.4 Variable Module Management System NOTE VMMS and ESS modes are mutually exclusive. If VMMS mode is enabled, ESS mode is disabled. In VMMS mode, the UPS operates as a traditional double-conversion UPS. However, the UPS will selectively shift the load to fewer UPMs based on the required load in order to force the remaining UPMs to carry a higher load.

  • Page 65: Battery Mode

    Figure 6-4. Path of current through the UPS in Energy Saver System If the bypass source falls outside of a predetermined voltage or frequency window, the system forward transfers to Battery mode and then to Normal mode with the inverter assuming the load. The transfer takes place with a 2 ms typical transfer time, to ensure loads being fed by the system output are not interrupted.

  • Page 66: Figure 6-5. Path Of Current Through The Ups In Battery Mode

    Figure 6-5. Path of current through the UPS in battery mode During a utility power failure, the rectifier no longer has an AC utility source from which to supply the DC output current required to support the inverter. The input contactor K1 opens and the battery instantaneously supplies energy to the battery converter.

If the load does not require a neutral and there is no neutral conductor connected at the bypass input, a neutral to ground bonding jumper must be installed.

    Figure 6-7. Typical maintenance bypass panel NOTE If installing, as part of the UPS system, a maintenance bypass without a rectifier input breaker, a minimum of two separate feeds with upstream feeder breakers, or one feed with two upstream feeder breakers, must be provided: one for the UPS and one for the maintenance bypass input. DO NOT use one feed or a single-feeder breaker to supply both the UPS and the maintenance bypass.

  • Page 70: Multiple Ups Distributed Bypass System

    The system is paralleled for capacity if all UPMs in a system are required to support the load. 6.4.1 Multiple UPS parallel system modes Similar to the single UPS system, the Eaton 9395 UPS parallel system supports a critical load in five different modes of operation. The standard operation modes are: NOTE The Variable Module Management System and Energy Saver System modes are mutually exclusive.

  • Page 71: Normal Mode - Distributed Bypass

    The UPSs continually monitor themselves and the incoming utility power and automatically switch between these modes as required, without operator intervention, except when manually switching to Bypass mode. The sophisticated detection and switching logic inside the UPSs ensures that operating mode changes are automatic and transparent to the critical load, while internal monitoring systems indicate the current mode of operation.

  • Page 72: Bypass Mode - Distributed Bypass

    6.4.3 Bypass mode – distributed bypass In Bypass mode, the output of the system is provided with three-phase AC power directly from the bypass input. While in this mode, the output of the system is not protected from fluctuations, spikes, or power outages from the source.

  • Page 73: Battery Mode - Distributed Bypass

    In the Parallel Redundant (N+1) arrangement, the bypass circuitry in each UPS operates to support the applied loads on bypass. If the UPSs are in NORMAL and one UPS trips offline, the remaining UPSs do not go to bypass as long as they have the capacity to support the load. In the Parallel Capacity (N+0) arrangement, if one UPS trips offline and goes to bypass, the remaining UPSs also go to bypass, if remaining UPSs can not support the load 6.4.4 Battery mode –...
