4.2 Liebert Services
Startup, UPS maintenance, DC source maintenance and training programs are available for the
Liebert NX UPS through your Emerson
®
sales representative.
4.2.1 Professional Startup
UPS Startup—Emerson
®
customer engineers perform a thorough non-powered inspection of the
units and will then conduct a complete electrical checkout. The DC source installation is also
inspected and placed on an initialization charge to ensure cell equalization. Customer Operation
training will be conducted during DC source charge time.
Load bank testing and full site acceptance testing are additional services that can be performed
during a UPS startup. One preventive maintenance service call can be added to the initial UPS
startup agreement.
Battery Installation/Startup—When purchased with a UPS Startup, this agreement provides
consistent, professional service for your entire UPS system. This one-source approach avoids conflicts
that may occur during a multisource installation. Note that Emerson
®
requires an installation
inspection for all batteries not installed by Emerson
®
customer engineers.
Battery IEEE Certification Inspection—The battery specialist will perform a detailed inspection
of the entire battery system to ensure it meets current IEEE standards.
Maintenance Agreements: The Signature Program
UPS Service Agreements—Liebert Services has a variety of available maintenance agreements,
depending on specific site needs. Choose the level of support appropriate for each installation.
Mission-critical sites can have the standard parts-and-labor, around-the-clock coverage for their UPS,
with or without scheduled preventive maintenance visits. Other sites can benefit from a variety of
money-saving options.
Emerson recommends two preventive maintenance visits per year for the UPS. The first can be
conducted with the UPS operational and includes an infrared scan of key UPS components.
The annual visit will require taking the UPS off line for a thorough non-powered inspection.
These visits are in addition to the general housekeeping tasks, such as changing air filters, that can
be performed by user personnel.
Battery Service Agreements—The same flexible Signature Program can also be applied to
contracts for battery maintenance. Again, the coverage needed will depend on the type of battery
purchased and the degree of support required from Liebert Services.
Training
User training courses include the proper operation of the system, emergency procedures, preventive
maintenance and some corrective maintenance.
Warranties
Contact Liebert Services if you have any questions regarding the warranty on your Liebert NX UPS
or the batteries.
