Emerson 610 installation manual Installation Considerations

Installation Considerations

1.0INSTALLATION CONSIDERATIONS

Install your Series 610 UPS in accordance with the submittal drawing package and the following pro- cedures.

A Liebert authorized representative must perform the initial system check-out and start-up to ensure proper system operation. Equipment warranties will be voided unless system start-up is performed by a Liebert authorized representative. Contact your local Liebert sales representative or Liebert Global Services at 1-800-LIEBERT to arrange for system start-up.

! CAUTION

Read this manual thoroughly before attempting to wire or operate the unit. Improper installation is the most significant cause of UPS start-up problems.

Do not install this equipment near gas or electric heaters. It is preferable to install the UPS in a restricted location to prevent access by unauthorized personnel.

1.Proper planning will speed unloading, location and connection of the UPS. Refer to Figures 13 through 78 and Appendix A.

2.Be certain that the floor at the final equipment location and along the route (inside the facility) to the installation site can support the cabinet weight and the weight of any moving equipment. The modules weigh from 5710 to 12,005 lbs. (2590 to 5445kg). The battery cabinets weigh from 3060 to 5300 lbs. (1388 to 2404kg). The System Control Cabinets weigh from 1000 to 5850 lbs. (454 to 2653kg). Refer to Appendix A. For switchgear weights, refer to your submittal package.

! WARNING

Locate center of gravity symbols and determine unit weight before handling cabinet.

3.Plan the route to ensure that the unit can move through all aisleways and doorways and around corners without risking damage. If the modules and batteries must be moved by elevator, check the size of the door openings and the weight-carrying capacity of the elevator.

4.Refer to information later in this manual regarding the optional battery cabinets and Transformer Cabinets. Observe all battery safety precautions when working on or near the battery.

5.Use the shortest output distribution cable runs possible, consistent with logical equipment arrangements and with allowances for future additions if planned.

6.Recommended ambient operating temperature is 77°F (25°C). Relative humidity must be less than 95%, non-condensing. Note that room ventilation is necessary, but air conditioning may not be required. Maximum ambient operating temperature is 104°F (40°C) without derating. The batteries should not exceed 77°F (25°C). At elevations above 4000 ft. (1219m), temperature derating may be required for full power output—consult your Liebert sales representative or call 1-800-LIEBERT.

7.Even though your Liebert UPS unit is at least 92-94% efficient, the heat output is substantial. For more specific information, see Appendix A. Be sure environmental conditioning systems can accommodate this BTU load, even during utility outages.

8.The installer should attempt to balance the load between the three output phases. The UPS will operate safely with an unbalanced load, but will give optimum performance if the three output phases are loaded within 20 percent of each other.

9.During normal UPS operations, short-term overload current demand from the bypass source may reach 10x the UPS output current rating. This overload current demand may be caused by the magnetizing inrush current of one or more downstream transformers or faults on downstream branch circuits. The instantaneous trip point(s) of the upstream bypass feeder breaker(s) must be set to support these temporary overloads. The magnitude of short-term overload bypass current demand is typically six to eight times the UPS current rating, but must be determined by analysis on a per-site basis. This analysis, generally known as an End-to-End Fault Coordination Study, must be done by a Registered Professional Engineer experienced in this activity and familiar with local codes and related requirements.

NOTE

While Liebert can provide typical guidelines, the responsibility for the proper breaker trip settings outside of the Liebert-manufactured UPS equipment resides with the owner. Contact Liebert Global Services at 1-800-LIEBERT for further details.
