3.2. Site Preparations
For the UPS system to operate at peak efciency, the installation site shall meet the environmental
parameters outlined in this manual. The operating environment must meet weight, cleanliness and specic
environmental requirements.
3.2.1. Environmental and Installation precautions
The air duct inlet environment must meet the following conditions:
• A difference of at least 1 Celsius degree (1.8 degrees Fahrenheit) shall be kept between the
dry bulb temperature and wet bulb temperature of the hygroscope to avoid condensation.
• According to ASHRAE90.1-2013, the maximum ambient temperature variation rate shall be
less than 3 degrees Fahrenheit/5 min (36 degrees Fahrenheit/h).
Precautions for environmental conditions for UPS operation:
The cooling methods used by some data centers may cause the UPS equipment room and/or the
data center’s internal temperature and relative humidity to be uneven. This cooling mode may
cause two problems:
• Firstly, it causes microclimate in the machine room. The microclimate can lead to persistent
variations of temperature and/or relative humidity within the room. For example, one side of
the room is always cooler than the other, regardless of the actual temperature.
• Second, it may induce variation in the temperature and/or relative humidity. This problem
occurs during the cooling system’s operating transitions.
Either of the above problems may lead to an unfavorable microclimate in the place where
the UPS is located. If the conditions in this microclimate exceed our company’s operating
specications, the UPS system’s stability may deteriorate over time. At the same time, these
extreme environments may also affect the stability of servers exposed therein.
The following guidance applies when installing the UPS system:
• The system shall be installed on a at oor suitable for computers and electronic devices.
• The UPS shall be installed in a clean, stable environment free of vibration, dust, high
humidity, ammable gases, ammable liquids, or corrosive substances.
• The ambient temperature of the UPS shall be controlled within 0–40
℃.
• It is advised that the battery pack shall be used in an ambient temperature within +20–+25
℃.
• Maximum relative humidity: 95%, non-condensing.
• This system must be installed in an indoor area with suitable temperature and humidity, free
of contaminants.
• The UPS shall normally operate at an altitude lower than 1,000m (3,300ft.). If it is to be used
at an altitude over 2,000m (6,600ft.), please call at Eaton’s hotline for more information.
• The warranty shall be invalid for failure to follow this guideline.
