Installation 2.0 INSTALLATION This section describes the Liebert APM’s environmental requirements and mechanical considerations that must be taken into account when planning the positioning and cabling of the UPS equipment. Because each site is unique, this section presents a guide to general procedures and practices that should be observed by the installing engineer, rather than step-by-step installation instructions. ! WARNING Risk of electric shock. Can cause injury, property damage and death.
PAGE 19
Installation 2.1 Initial Inspections 1. While the Liebert APM and ancillary cabinets are still on the truck, inspect the equipment and shipping container for any signs of damage or mishandling. Do not attempt to install the system if damage is apparent. If any damage is noted, file a damage claim with the shipping agency immediately and contact Liebert Services at 1-800-LIEBERT to inform them of the damage claim and the condition of the equipment. 2.
PAGE 20
Installation 2.3.2 Environmental Considerations Before installing the Liebert APM, verify that the UPS room satisfies the environmental conditions stipulated in 11.2 - UPS Environmental, paying particular attention to the ambient temperature and air exchange system. The UPS unit should be installed in a cool, dry, clean-air environment with adequate ventilation to keep the ambient temperature within the specified operating range 32°F to 104°F (0°C to 40°C).
PAGE 21
Installation 2.5 Mechanical Considerations The Liebert APM is constructed with a steel frame and removable panels. Top and side panels are secured to the chassis by screws. The doors may be opened for access to power connections bars, auxiliary terminals blocks and power switches. The UPS comes with an Operator Control Panel that provides basic operational status and alarm information. The cabinet houses both the power components and the internal batteries. Cooling is provided by internal fans.
PAGE 22
Installation 2.5.4 Special Considerations for Parallel Systems 1. Consider the grounding configuration of the UPS system before finalizing module placement. For optimal ground performance, the Liebert APM modules should be close together. See 3.2.6 Cabling Guidelines. 2. For optimal load-sharing performance, the UPS bypass input cables and output cables should be approximately the same length, ±10 percent. 3.
PAGE 23
Installation 2.6.1 Optional Cabinets If the Liebert APM installation includes a Liebert BDC, the UPS must be positioned to allow the Liebert BDC to be bolted to right side of the Liebert APM (see Figure 1). The Liebert BDC must be cabled and bolted to the Liebert APM before the UPS and bypass cabinet are moved into their final position. Connect the input wiring to the Liebert BDC ONLY after the units are connected and positioned.
