Installation

1.2Internal Inspections

1.Remove any packaging material, then visually examine the UPS and battery equipment for transit damage, both internally and externally. Report any such damage to the shipper and to Liebert immediately.

2.Check the nameplate inside the cabinet door to verify that the model number and rating correspond to the ones specified. Record the model number and serial number in the front of this installation manual. This information is necessary should service be required.

3.Check for loose connections or unsecured components in the cabinet.

4.Check for shipping damage to internal components.

1.2.1Storing for Delayed Installation

If the equipment will not be installed immediately, it must be stored indoors where the humidity is no higher than 90% and the temperature is no higher than 104°F (40°C). The storage area must protect the Liebert NX from excessive moisture (see 5.2 - UPS Environmental).

! CAUTION

If the battery cabinet must remain disconnected from power for more than six (6) months, the battery must be recharged before use. To charge the batteries, the battery cabinet must be connected to the Liebert NX UPS and the UPS must be connected to utility power and started up because the charger operates only while the Liebert NX UPS is operating.

! CAUTION

When batteries are installed in a cabinet adjacent to the UPS unit, the battery—not the UPS—dictates the designed maximum ambient operating temperature.

1.3Preliminary Checks

1.3.1Identification

The equipment supplied has an identification tag on the back of the main door listing the type and size of the UPS.

1.4UPS Location

1.4.1Positioning the UPS

Choose a location for the UPS that offers:

•Easy connection to inputs, outputs and auxiliary equipment

•Enough space to service the UPS

•Air circulation sufficient to expel heat produced by UPS

•Protection against moisture and excessive humidity

•Protection against dust and other particulate matter

•Compliance with fire prevention regulations and practices

•Operating environment temperature of 74-80°F (23-27°C) for maximum battery efficiency

1.4.2Environmental Considerations

Before installing the Liebert NX, verify that the UPS room satisfies the environmental conditions stipulated in 5.2 - 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).

For optimal UPS and battery system performance and service life, maintain the operating tempera- ture within the range of 74-80°F, (23-27°C).

The Liebert NX UPS cooled by internal fans. Cooling air enters the unit through the front of the unit and is exhausted out the top. To permit proper air flow and prevent overheating, do NOT block or cover the ventilation openings or blow air down onto the unit. Ventilation clearance above the unit must be a minimum of 8 in. (203mm).

See Table 7 for details on heat dissipation.
