Vertiv Liebert APM Plus - 3.6 Environmental Requirement

3.6 Environmental Requirement
3.6.1 UPS Location Selection
The UPS should be located in a cool, dry, clean-air indoor environment with adequate ventilation, and should be located on
concrete or other non-flammable and flat surfaces. The ambient environment should be free of conductive powder (such as
metallic powder, sulfide, sulfur dioxide, graphite, carbon fiber, conductive fiber, etc.), acid mist or other conductive media
(strongly ionized substances). The environment specifications should comply with relevant international standard &
specifications and the operating range (see Table 12.2 on page172) specified in this manual.
The UPS uses forced cooling by internal fans. Cooling air enters the UPS through the ventilation grills at the front of the
cabinet and exhaust through the ventilation grills at the back of the cabinet. Do not obstruct the ventilation holes (ventilation
grills). The rear of the UPS should be kept a distance at least 500 mm from the wall to avoid blocking the UPS heat dissipation,
thus reducing the UPS internal temperature and improving the UPS life.
If necessary, install indoor extractor fans to aid cooling-air flow to avoid room temperature buildup. Air filters (optional) should
be used when the UPS is to operate in a dirty environment.
N O T E: W hen the battery cab inet is installed near the U PS, the maxim um allow ab le am bient
tem perature is dep endent on the battery rather than the UPS.
N O T E: If the UP S is w orking in EC O m ode, the pow er consum p tion will be less than that in Norm al
m ode. Proper air cond itioning system shall be selected according to the norm al operating m od e.
3.6.2 Battery Location Selection
Batteries generate some amount of hydrogen and oxygen at the end of charge, so the fresh air volume of the battery
installation environment must meet the EN50272-2001 requirements.
The ambient temperature is the main factor that affects the battery capacity and life. The normal operating temperature of
the battery is 20 °C. If the ambient temperature is higher than 20 °C, the battery life will be reduced. If it is lower than 20 °C, the
battery capacity will be reduced. In normal situation, the allowable ambient temperature for the battery is 15 °C to 25 °C. The
ambient temperature of the battery shall be maintained constant, and the battery shall be kept away from heat source and air
outlet.
Battery can be installed inside the specialized battery cabinet which shall be close to the UPS. If the battery is placed on the
raised floor, bracket shall be installed under the floor, just as for the UPS. If the battery adopts rack mounting or is mounted far
from the UPS with other installation mode, the battery circuit breaker shall be installed near the battery, and the cabling
distance shall be minimized.
3.6.3 Storage
If the UPS is not installed immediately, it must be stored with the original packaging in a room for protection against excessive
humidity and heat source (see Table 12.2 on page172). The battery needs to be stored in a dry and cool place with good
ventilation. The most suitable storage temperature ranges from 20 °C to 25 °C.
W ARN ING ! D urin g battery storage, periodically charge the battery according to the battery
m anufacturer instructions. In the charge process, tem porarily connect the U P S to the mains
and activate the b attery by rechargin g the battery.
