Single-Module Mechanical Installation

1.3.2Storage

Should the equipment not be installed immediately, it must be stored in a room for protection against excessive humidity and or heat sources (see Environmental Parameters in Table 6).

1.4Positioning

The cabinet is structurally designed to handle lifting from the base.

Access to the power terminals, auxiliary terminals blocks and power switches is from the front.

The door can be opened to give access to the power connections bars, auxiliary terminal blocks and power isolators. Front door can be opened at 180° for more flexibility in installations.

1.4.1Moving the Cabinets

The route to be travelled between the point of arrival and the unit’s position must be planned to make sure that all passages are wide enough for the unit and that floors are capable of supporting its weight (for instance, check that doorways, lifts, ramps, etc. are adequate and that there are no impassable corners or changes in the level of corridors).

Ensure that the UPS weight is within the designated surface weight loading (kg/cm2) of any handling equipment. For weight details, see Table 6.

The UPS can be handled with a forklift or similar equipment. Ensure any lifting equipment used in moving the UPS cabinet has sufficient lifting capacity. When moving the unit by forklift, care must be taken to protect the panels. Do not exceed a 15-degree tilt with the forklift. Bottom structure will sup- port the unit only if the forks are completely beneath the unit.

Handling with straps is not authorized.

! WARNING

Risk of heavy unit falling over. Improper handling can cause equipment damage, injury or death.

Because the weight distribution in the cabinet is uneven, use extreme care while handling and transporting. Take extreme care when handling UPS cabinets to avoid equipment damage or injury to personnel.

The UPS module weight ranges from 3965 to 5250lb (1768 to 2381kg).

Locate center of gravity symbols

and determine unit weight before handling each

cabinet. Test lift and balance the cabinets before transporting. Maintain minimum tilt from vertical at all times.

1.4.2Clearances

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 24" (610mm) between the top of the UPS and any over- head obstacles to permit adequate circulation of air coming out of the unit.

1.4.3Floor Installation/Anchoring

If the equipment is to be located on a raised floor it should be mounted on a pedestal suitably designed to accept the equipment point loading. Refer to the base view to design this pedestal.

1.5System Composition

A UPS system can comprise a number of equipment cabinets, depending on the individual system design requirements, e.g. UPS cabinet, battery cabinet, maintenance bypass cabinet. In general, all the cabinets used in a particular installation are of the same height. Refer to the drawings provided in

4.0- Installation Drawings for the positioning of the cabinets as shown in Figure 1.
