    NSTRUCTIONS SAVE THESE INSTRUCTIONS This manual contains important instructions that should be followed during installation of your Liebert NXL ™ UPS. Read this manual thoroughly, paying special attention to the sections that apply to your installation, before working with the UPS. Retain this manual for use by installing personnel.
  • Page 8 NOTE Materials sold hereunder cannot be used in the patient vicinity (e.g., use where UL, cUL or IEC 60601-1 is required). Medical applications such as invasive procedures and electrical life support equipment are subject to additional terms and conditions. NOTICE This unit complies with the limits for a Class A digital device, pursuant to Part 15 Subpart J of the FCC rules.

    (see Environmental Parameters in Table 11). The Liebert NXL UPS is cooled with the aid of internal fans. To permit air to enter and exit and prevent overheating or malfunctioning, do not cover the ventilation openings.

  • Page 10: Storage

    1.4.2 Clearances The Liebert NXL has no ventilation grilles at either side or at the rear of the UPS. Clearance around the front of the equipment should be sufficient to enable free passage of personnel with the doors fully opened. It is important to leave a distance of 24in (610mm) between the top of the UPS and any overhead obstacles to allow the module to be serviced and to permit adequate circulation of air coming out of the unit.

  • Page 11: Raised-Floor Installations

    The cabling impedance must be carefully controlled to ensure good bypass current sharing. For Liebert NXL Systems, the cabling impedances must be within 10% from maximum to minimum. If the cabling impedances need to be greater than 10%, contact your Emerson representative to calculate whether the system will result in an overload condition when operating on bypass.

  • Page 16: Control Cable And Communication

    UPS Electrical Installation Control Cable and Communication Based on your site’s specific needs, the UPS may require auxiliary connections to manage the battery system (external battery circuit breaker), communicate with a personal computer or provide alarm signaling to external devices, or for Remote Emergency Power Off (REPO). The External Interface Board, arranged for this purpose, is next to the option box in the Rectifier section (refer to 4.0 - Installation Drawings).

  • Page 25: Configuring Neutral And Ground Connections

    UPS Electrical Installation Configuring Neutral and Ground Connections Improper grounding is the largest single cause of UPS installation and startup problems. Grounding techniques vary significantly from site to site, depending on several factors. Proper grounding should be based on the appropriate NEC sections, but safe and proper equipment operation requires further enhancements.
