Single Module UPS Installation

1.4.5Clearances

The Liebert NX has no ventilation grilles at either side of the UPS. To enable routine tightening of power terminations within the UPS, in addition to meeting any local regulations, Liebert recom- mends providing adequate clearance in the front of the equipment for unimpeded passage of person- nel with the doors fully opened. It is important to leave 800mm (31.5") clearance above the UPS to permit adequate circulation of air coming out of the unit.

1.4.6Access

The component layout of the UPS supports front and top access while servicing, diagnosing and repairing the UPS, thus reducing the space requirement for side and rear access.

1.4.7Final Positioning

The UPS cabinets are fitted with casters on the base to allow ease of movement and positioning.

! WARNING

Casters are strong enough for movement across even surfaces only. Caster failure could occur if they are subjected to shock loading.

When the equipment has been finally positioned, ensure the adjustable feet are set so that the UPS will remain stationary and stable.

1.4.8Floor Anchoring

Diagrams in 5.0 - Installation Drawings show the location of the holes in the base plate through which the equipment may be bolted to the floor. If the equipment is to be installed on a raised floor it should be mounted on a pedestal suitably designed to accept the equipment point loading.

1.4.9Cable Entry

Cables can enter the Liebert NX UPS and battery cabinet from below. Cable entry is made possible by removing a blanking piece fitted at the bottom of equipment to reveal the cable entry hole.

Top Cable Entry—Optional

Optionally a top cable entry extension may be used. The cabinet extends the overall width of the UPS and permits connection of all incoming AC/DC power cables from above.

The top cable entry option is fitted on the side of the UPS cabinet and is supplied without side panels; the side cover from the UPS being used.

The cabinet with cables coming in from the top for the 30-40 kVA UPS must be positioned on the left side; the cabinet for the 60 to 200 kVA UPS can be positioned on either side.

This facilitates cable entry through the top metal panel after the appropriate cable entry holes have been cut.

NOTE

The top cable entry also includes the power connection cables between the cabinet and the UPS.

1.5External Protective Devices

Circuit breakers or other protective devices must be installed in the AC supply, external to the UPS. This chapter provides guidelines for qualified installers who must have knowledge of local wiring practices pertaining to the equipment to be installed.
