Vertiv Liebert EXS - Installation and Commissioning; Pre-Installation Preparation; Clearance Requirements

3 Installation and Commissioning
Installation must be performed by properly trained and qualified personnel. Do not start the UPS until the installation is
finished, and the system is commissioned by an authorized engineer.
WARNING! Risk of electrical shock. Can cause property damage, injury, and death.
The unit has several circuits that are energized with high DC and AC voltages. Check for voltage with both
AC and DC voltmeters before making contact and before working within the UPS. Only properly trained and
qualified personnel wearing appropriate, OSHA approved personal protective equipment (PPE) should
prepare for installation, install, and maintain the equipment. When performing maintenance with any part of
the equipment under power, service personnel and test equipment must stand on rubber mats.
WARNING! Risk of electrical shock. Can cause equipment damage, injury and death.
Before beginning installation, verify that all external overcurrent protection devices are open (Off), and that
they are locked out and tagged appropriately to prevent activation during the installation. After the power
cables are connected, the terminal block’s protective cover must be reinstalled to remove the electric shock
hazard.
WARNING! Risk of heavy unit falling over. Improper handling can cause equipment damage, injury, and death.
Exercise extreme care when handling unit cabinets and rack mounted units to avoid equipment damage or
injury to personnel. The UPS weighs between 1,041.1lb(460kg) and 1,3883.9lb(630kg) depending upon the
number of battery strings in the system. See Table 8.2 on page61, for the specific weights. Locate center of
gravity symbols and determine unit weight before handling. Test lift and balance the cabinets before
transporting. Maintain minimum tilt from vertical at all times. Slots at the base of the module cabinets are for
forklift use. Forklift slots support the unit only if the forks are completely beneath the unit.
NOTE: These are general installation procedures and methods. Because each site is different, consider the site
conditions and requirements when planning and conducting the installation.
3.1 Pre-Installation Preparation
Before installation, consider the environmental requirements, service clearances, and external protective devices when
planning the final location of the UPS system.
3.1.1 Environment of installation area
Install the UPS in a clean, well ventilated environment with the ambient temperature within the specifications listed in Table
8.1 on page59.
3.1.2 Clearance required forinstallation,maintenance,andoperation
Internal fans provide forced air cooling for the UPS. Cooling air enters through the front panel and hot air is exhausted through
the back.
