1.0 INSTALLATION 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.
1. Proper planning will speed unloading, location and connection of the UPS. Refer to Figures 10
through 60 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
UPS modules can weigh from 5775 to 12100 lbs. (2619 to 5488kg). The battery cabinets weigh
from 3060 to 5300 lbs. (1388 to 2404kg) each. Refer to Appendix A.
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 cabinet(s), Maintenance
Bypass Cabinet and Transformer Cabinet. 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 92 to 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.
!
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.
!
WARNING
Locate center of gravity symbols and determine unit weight before handling cabinet.
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.
