3 Introduction to Eaton UPS

The Eaton 93E 15-80 kVA uninterruptible power supply (UPS) is a true online, continuous-duty, transformer-free, double-conversion, solid-state, 3-phase system that provides conditioned and uninterruptible AC power to protect the loads connected to it from power failures.

The Eaton 93E 15-80 kVA online power protection system is used to prevent loss of valuable electronic information, minimise equipment downtime, and minimise the adverse effect on production equipment due to unexpected power problems.

The Eaton 93E 15-80 kVA UPS continually monitors incoming electrical power and removes the surges, spikes, sags, and other irregularities that are inherent in commercial utility power. Working with a building's electrical system, the UPS system supplies clean, consistent power that sensitive electronic equipment requires for reliable operation. During brownouts, blackouts, and other power anomalies, batteries provide emergency power to safeguard operation of the load equipment.

The UPS is housed in a single free-standing cabinet, with safety shields behind the door for hazardous voltage protection.

This manual is for Eaton 93E series UPS, refer Section 10.1 for product models.

Figure 1 shows the Eaton 93E 15-80 kVA UPS.

NOTE: Start-up and operational checks must be performed by a qualified service personnel authorized by Eaton. If these instructions are not followed, the warranty terms specified in Chapter 11 become void. This service is offered as a part of the sales contract for the UPS. Contact Eaton service representative in advance to reserve a preferred startup date.

Document ID: 614-01975-00

20 (133)

Eaton 93E UPS 15-80 kVA (380/400/415 V) Installation and Operation Manual

3.1.3 Communication interface

• Signal input monitoring

Up to 3 inputs in the UPS are available to connect the facility's alarm system contacts. Some system configurations may limit the number of inputs available. The UPS uses these inputs to monitor the signal inputs in addition to the UPS status. For more information, see Chapter 8.

• MiniSlot communication bays

2 communication bays are standard equipment. One to 2 optional MiniSlot connectivity cards can be installed in the UPS module at any time. MiniSlot cards are quickly installed at the front of the UPS (behind the door) and are hot-pluggable. For more information, see Chapter 8.

3.1.4 High-efficiency mode

The Eaton 93E Series UPS offers a high-efficiency (HE) normal mode with double-conversion on demand. This mode allows the Eaton 93E UPS to achieve 98% efficiency while still protecting the load. For information on how to set the UPS to work in the high efficiency mode, see Chapter 7.

3.1.5 Advanced Battery Management

A 3-stage charging system increases the battery service life by optimizing the recharge time. It also protects the batteries from damage due to high current charging and inverter ripple currents.

3.1.6 Maintenance bypass

The internal maintenance bypass for the 15-80 kVA models consists of input, output, neutral and bypass input (dual feeds) switches used to control the AC input to the UPS. The inverter output and the maintenance bypass switch are used to partially isolate the UPS so that a limited number of components can be serviced without interrupting power to the critical systems.

3.2 Options and accessories

Contact your Eaton sales representative for more information about the available options and accessories.

Eaton 93E UPS 15-80 kVA (380/400/415 V) Installation and Operation Manual

3.2.1 External battery cabinet

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.

3.2.2 Parallel system

A parallel UPS system with up to 4 UPSs can be installed to provide a parallel capacity and/or redundant system. This load sharing system provides more capacity than a single UPS, and can provide redundancy, 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.

Module output breakers (MOBs) allow the output of a UPS to be disconnected from other UPSs and the system load for maintenance and service. Design considerations assume that each UPS has a module output breaker (MOB). The breaker should also disconnect the neutral for improved safety during maintenance.

The MOB must have at least one normally open (N.O.) and one normally closed (N.C.) contact. These contacts must not share a common terminal. 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. Figure 24 and Figure 25 show the principles of paralleled UPS systems including MOBs and outputs from UPSs.

3.2.3 Monitoring and communication

Optional MiniSlot cards support several alternative communication interfaces, such as WEB/SNMP, RELAY / RS-232 and Modbus. For more information on the monitoring and communication features, see Chapter

4.3 Site preparations

For the UPS system to operate at peak efficiency, the installation site must meet the environmental parameters outlined in these instructions. If the UPS needs to be operated at an altitude higher than 1 000 m (3 300 ft) contact your service representative for important information about high altitude operation. The operating environment must meet the height, clearance, and environmental requirements specified.

4.3.1 Environmental and installation considerations

The UPS system installation must meet the following guidelines:

• The system shall be installed indoors on a level floor suitable for

computer or electronic equipment.

• The system shall be installed in a temperature and humidity

controlled area in which the dew point cannot be reached and that is free of conductive contaminants.

Failure to follow guidelines may void your warranty.

The UPS equipment operating environment must meet the weight requirements shown in Table 1, and the size requirements shown in Figure 2 through Figure 6. Dimensions are in millimeters (inches).

• Some models that feature rear connections also require additional

rear clearance to enable installation and connection.

CAUTION

If battery systems are located in the same room as the UPS, follow the battery manufacturer's environmental requirements if they are more stringent than the UPS requirements. Operating temperatures above the recommended range result in decreased battery life and performance, and may reduce or void the battery warranty.

It is required that ventilation of the UPS room is arranged. Sufficient amount of air cooling is needed to keep the maximum room temperature rise at the desired level:

• Temperature rise of +5 °C maximum requires the airflow of 600

• Temperature rise of +10 °C maximum requires the airflow of

An ambient temperature from +20 °C to +25 °C is recommended to achieve a long life of the UPS and batteries. The cooling air that enters the UPS must not exceed +40 °C. Avoid high ambient temperature,
