Installation

1.4.3Special Considerations for 1+N Systems

1.Consider the grounding configuration of your system before finalizing module placement. For optimal ground performance, the NX modules should be close together.

2.For optimal load-sharing performance, the UPS output cables should be approximately the same length, plus or minus 20 percent.

3.Position modules in such a way as to minimize the length of power cables and control wiring between UPS modules and the paralleling cabinet.

1.5Considerations in Moving the NX

Ensure that the UPS weight is within the designated surface weight loading (lb./ft2 or kg/cm2) of any handling equipment. See Table 9 for weights of various units.

To move the UPS and optional battery cabinets:

•The NX may be rolled on its casters when moving the unit a short distance. For longer distances, move the UPS with a forklift or similar equipment to ease the relocation and to reduce vibration.

The optional battery cabinets should be moved with a forklift or similar equipment.

! WARNING

Ensure that any equipment that will be used to move the NX has sufficient lifting capacity. The NX weight ranges from 850 to 1400 lb. (386 to 635kg). See Table 9 for details. The UPS presents a tipping hazard. Do not tilt the NX further than 15 degrees from vertical.

The UPS is fitted with casters—take care to prevent movement when unbolting the equipment from its shipping pallet. Ensure adequate personnel and lifting equipment are available when taking the NX off its shipping pallet. Do not tilt the unit more than 15 degrees from center.

! WARNING

The casters are strong enough for movement across even surfaces only. Casters may fail if they are subjected to shock loading, such as being dropped or rolled over holes in the floor or obstructions. Such failure may cause the unit to tip over, injuring personnel and damaging the equipment.

Care must be taken when maneuvering units fitted with batteries. Keep such moves to a minimum. For further information, see Battery Cabinet Precautions on page 2.

Final Position

When the equipment has been finally positioned, ensure that the adjustable stops are set so that the UPS will remain stationary and stable (see 7.0 - Installation Drawings).

1.6Mechanical Considerations

The NX 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 termi- nals blocks and power switches.

The UPS comes with an operator control panel, which provides basic operational status and alarm information. The cabinet houses both the power components and the internal batteries. Cooling is provided by internal fans. The unit sits on four casters. Adjustable stops are provided to prevent the UPS from moving once it has been moved to its final position.
