2-4. Setting up the UPS

1. UPS should be mounted in a rack or on a flat, clean surface area away from vibration, dust, humidity, high temperatures, liquids, gases, or corrosive and conductive contaminants. Avoid high-traffic areas, near windows and doors. Maintain a minimum clearance of 100mm from the bottom of the UPS to avoid dust and high temperature.

1. Maintain an ambient temperature range of 0^ to 45^ for optimal operation. Every 5^ above 45^ , will reduce 12% of the UPS' nominal capacity at full load. The highest acceptable working temperature for UPS operation is 50^ .

2. An altitude of 1000m is the maximum allowable in order to keep the UPS at normal operation under full load. Use at high altitudes requires a reduced power load. Altitude de-rating power with connected loads for UPS normal operation is listed as below:

Altitude m	Derating factor \( {}^{1)} \)
1000	1.0
1500	0.95
2000	0.91
2500	0.86
3 000	0.82
3500	0.78
4 000	0.74
4 500	0.7
5 000	0.67
NOTE - Note to table 1
Based on density of dry air \( = {1.225}\mathrm{\;{kg}}/{\mathrm{m}}^{3} \) at sea-level, +15 °C.
1) Since fans lose efficiency with altitude, forced air-cooled equipment will have a smaller derating

1. The UPS is equipped with an internal fan for cooling. For proper heat dissipation and accessibility, place the UPS in a well-ventilated area with a minimum clearance of 100mm to the front of the UPS and 300mm to the back and sides.
