2 Introduction to Eaton UPS The Eaton® 93PM uninterruptible power supply (UPS) is a true online, continuous-duty, transformerless, double-conversion, solid-state, three-phase system, supplying conditioned and uninterruptible AC power to critical load and protecting it from power failures. The UPS is used to prevent loss of valuable electronic information, minimize equipment downtime, and minimize the adverse effect on production equipment due to unexpected power problems.
Figure 2-1: Eaton 93PM UPS 2.1 Looking inside the UPS system The system level static bypass in the Eaton 93PM UPS cabinet determines the attainable output power of the UPS. The static bypass line consists of static switch and a backfeed protection isolation device connected in series. In addition, there is a system level control unit that constantly monitors the power delivered through the bypass line or to the input of the UPS.
The 30-50 kW 93PM UPS includes a 50 kW rated static bypass section, one UPM power module, and internal batteries. In addition to the internal batteries, also external batteries can be connected. The main components of this UPS are depicted in Figure 2-2: 93PM 50 kW UPS wiring diagram on page 11.
Figure 2-2: 93PM 50 kW UPS wiring diagram P-164000249 Revision 2 30-200 kW User's and Installation Guide 11
In the 80-200 kW units, the UPM power modules are paralleled internally. These units do not include internal batteries. Figure 2-3: 93PM 150 kW UPS wiring diagram on page 12 shows the construction of the 150 kW 93PM UPS with three power modules.
The rectifier input switch and battery breaker are available as standard for the 30-50 kW units, and as optional for the 80-150 kW units. The internal MBS is available as optional for the 30-150 kW units. These options are not available for the 160-200 kW units, and will have to be included externally in the installation.
Internal relay contacts Figure 2-4: Path of current through the UPS in double conversion mode Three-phase AC input power is converted to DC using a multilevel converter with IGBT devices to produce a regulated DC voltage to the inverter. The UPS status indicated on the display is “Unit Online” and the UPM status is “Active”. The battery converter derives its input from the regulated DC output of the rectifier and provides regulated charge current to the battery.
2.2.1.2 Energy Saver System mode In ESS mode the UPS safely provides mains current directly to the load when the input is within the acceptable limits by its voltage and frequency. The UPS status indicated on the display is “Unit Online ESS”, and the UPM status is “Active”. Surge protection and some filtering is also provided, ensuring that clean power is delivered to the load equipment.
Internal relay contacts Battery breaker Figure 2-6: 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 relay K1 opens and the UPS output is powered from batteries through the inverter. As the inverter operates uninterrupted through the transition, the load remains supported continuously without disturbance.
NOTE The critical load is not protected while the UPS is in Bypass mode. Internal relay contacts Figure 2-7: Path of current through the UPS in bypass mode 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.
2.3.1 Advanced Battery Management Advanced Battery Management technology uses sophisticated sensing circuitry and a three-stage charging technique that extends the useful service life of UPS batteries while optimizing the battery recharge time. ABM also protects batteries from damage caused by high current charging and inverter ripple currents. Charging at high currents can overheat and damage batteries. In charge mode, the batteries are recharged.
2.5 Options and accessories Contact an Eaton sales representative for information about the available options. 2.5.1 Maintenance Bypass Switch The Maintenance Bypass Switch (MBS) enables power to completely bypass and isolate the UPS so that the UPS can be safely serviced or replaced without interrupting power to critical systems. An internal maintenance bypass switch is provided as a factory installed option for 30-150 kW units.

Figure 4-8: Connections of the EPO switch From remote EPO switch To customer interface Terminal block EPO in UPS cabinet NO 1-2 NC 3-4 Remarks Wire jumper between 1-2 must be installed for proper functions. Table 4-1: Remote EPO wire terminations 4.5 Installing interface connections 93PM UPS contains a total of five (5) signal input connectors for customers which can be used for giving remote control commands to the UPS. Customer interface connector CN5 can be used for these purposes.
4.5.2 Battery breaker wiring interface When using the original accessory battery cabinet from the manufacturer, the battery breaker interface wiring is provided with the cabinet. Connecting it requires only routing the wires from the cabinet to the bottom section of the UPS. The connector for the battery circuit breaker monitoring signal and battery circuit breaker trip signal are to the left from the power cabling.
4.6 Wiring parallel 93PM UPS systems The outputs of multiple 93PM UPS systems can be connected in parallel. Up to four (4) units can be paralleled. The UPS static bypass power rating needs to be identical among all paralleled units. However, paralleled UPS cabinets can be housed with different number of UPM power modules. The outputs are paralleled to increase the load capacity of the power system and for redundancy.
MOB’s Module Output Breakers (MOBs) allow the output of the UPS to be disconnected from the other UPSs and system load for maintenance and service. Design considerations assume that each UPS has a Module Output Breaker (MOB). The breaker shall not disconnect neutral. The MOB must have a Form “C” auxiliary contact. The N.C contact is connected to the corresponding UPS’s input used for signal input. The N.O. contact is used to disconnect the Bypass Pull-Chain when the MOB is open.
4.6.2 Control signals overview Two controls signals (External CAN Network, Bypass Pull-Chain) are required for external paralleling. Both of these control signals are fault tolerant and alarmed when disconnected. External CAN (ECAN) ECAN provides means for communications between the UPS’s in a parallel system. The system will continue to share load and protect the load when this network fails.
Figure 4-11: Simplified CAN and Pull-Chain wiring for parallel UPS system NOTE This drawing is for distributed bypass wiring purposes and is not a floor layout plan. UPSs can be placed in any physical order. NOTE External CAN connections between UPSs require shielded twisted pair wire. NOTE Use twisted pair wiring between the UPS and MOB AUX contacts.
Figure 4-13: CAN and Pull-Chain wiring for parallel UPS without MOBs NOTE NC and NO designations on MOB AUX contacts are defined with breaker in OFF (open) position. If MOB contacts have pigtail leads, use the same wire gauge to connect to the UPS and use the correct crimp connections for the wire gauge. External CAN connections between UPS cabinets require shielded twisted pair wire. Use twisted pair wiring between the UPS and MOB AUX contacts. Always confirm contact operation prior to wiring.
