Remote EPO switch dimensions 2.2.2 UPS system power wiring preparation 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.
For external wiring requirements, including the minimum size of external wiring, see Table 2-4. The power wiring connections for this equipment are rated at 70°C. If wire is run in an ambient temperature greater than 30°C, higher temperature wire and/or larger size wire may be necessary. Units kVA kW Volts Basic unit rating at 0.9 lagging pF load Input and output voltage AC input to UPS rectifier (0.98 Min.
Terminals E1 through E12 are 2-hole bus bar mountings for standard NEMA 2-hole barrel lugs. See Table 2-5 for power cable terminations and Table 2-6 for recommended installation parts and tools not supplied by Eaton Corporation. Figure 3-4 and Figure 3-5 show the location of the power cable terminals inside the UPS.
The line-to-line unbalanced output capability of the UPS is limited only by the full load per phase current values for AC output to critical load shown in Table 2-4. The recommended line-toline load unbalance is 50% or less. Source protection for the AC input to bypass should be treated as if supplying a 275 kVA threephase transformer, to allow for inrush current. Bypass input wiring and bypass input breaker rating should be treated as if supplying a 275 kVA load, regardless of the rating of the UPS.
Read and understand the following notes while planning and performing the installation: • Install the interface wiring (for example, building alarm, relay output, battery breaker trip, and X-Slot) separate from the power wiring. The wiring should have double insulation and rated at Uo/U = 300/500 Volts. • All interface wiring is to be provided by the customer. • When installing internal interface wiring to X-Slot terminals, route the wiring through the internal opening in the X-Slot communication bay.

4 Understanding UPS operation 4.1 Looking inside the UPS system The Powerware 9395 UPS is a continuous-duty, solid-state, transformerless (at 400 Vac), threephase, 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. Figure 4-1.
4.2 Modes The Powerware 9395 UPS supports a critical load in three different modes of operation. The UPS can automatically use all three modes, as required. The standard operation modes are: • • • In Normal mode, the critical load is supplied by the inverter, which derives its power from rectified utility AC power. In this mode, the battery charger also provides charging current for the battery, if needed. In Battery mode, the battery provides DC power, which maintains inverter operation.
The inverter produces a three-phase AC output to a customer’s load without the use of a transformer. The inverter derives regulated DC from the rectifier and uses IGBT devices and pulse-width modulation (PWM) to produce a regulated and filtered AC output. The AC output of the inverter is delivered to the system output through the output contactor K3.
In bypass mode, the output of the system is provided with three-phase AC power directly from the system input. While in this mode, the output of the system is not protected from voltage or frequency fluctuations or power outages from the source. Some power line filtering and spike protection is provided to the load but no active power conditioning or battery support is available to the output of the system in the bypass mode of operation.
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. The converter either bucks or boosts the voltage so that the inverter can support the customer’s load without interruption. If bypass is common with the rectifier input, the backfeed protection contactor K5 also opens.
NOTE If the load requires a neutral, a bypass source neutral must be provided. 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. DO NOT install both a source neutral and a bonding jumper. Figure 4-5.
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. Figure 4-6.
5 UPS operating instructions This section describes how to operate the UPS. NOTE Before starting the UPS, ensure all installation tasks are complete and a preliminary startup has been performed by authorized service personnel. The preliminary startup verifies all electrical interconnections to ensure the installation was successful and the system operates properly.
