Installation
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 NX from excessive moisture (see 6.2 - UPS Environmental).
! CAUTION
If the UPS must remain disconnected from power for more than six (6) months, the battery must be recharged before use. To charge the batteries, the unit must be connected to utility power and started
! CAUTION
When batteries are installed in the UPS or are
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
1.4.2Environmental Considerations
Before installing the NX, verify that the UPS room satisfies the environmental conditions stipulated in 6.2 - UPS Environmental, paying particular attention to the ambient temperature and air exchange system.
The UPS unit should be installed in a cool, dry,
For optimal UPS and battery system performance and service life, maintain the operating tempera- ture within the range of
The 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 24 in. (610mm).
See Table 9 for details on heat dissipation.
Battery Location
Temperature is a major factor in determining battery life and capacity. Battery manufacturers recom- mend an operating temperature of 77°F (25°C). Ambient temperatures warmer than this reduce bat- tery life; temperatures below this reduces battery capacity. In a typical installation, battery temperature should be maintained between 74°F and 80°F
