The ambient temperature is the main factor that affects the battery capacity and life. The normal operating temperature of
the battery is 68 °F (20 °C). If the ambient temperature is higher than 68 °F (20 °C), the battery life will be reduced. If it is lower
than 68 °F (20 °C), the battery capacity will be reduced. In normal situation, the allowable ambient temperature for the battery
is 59 °F (15 °C) to 77 °F (15 °C). The ambient temperature of the battery must be maintained constant, and the battery must be
kept away from heat source and air outlet.
Battery can be installed inside the specialized battery cabinet that must be close to the UPS. If the battery is placed on the
raised floor, a bracket must 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 must be installed near the battery, and the cabling
distance must be minimized.
3.6.3 Storage
If the UPS will not be installed immediately, it must be stored with the original packaging indoors in a clean, dry, and cool
location which should be protected from excessive humidity and heat sources (see Table 12.2 on page171). The battery
needs to be stored in a dry and cool place with good ventilation. The most suitable storage temperature ranges from 68 °F (25
°C) to 77 °F (25 °C).
WARNING! During battery storage, periodically charge the battery according to the battery manufacturer
instructions. In the charging process, temporarily connect the UPS to the mains and activate the battery by
recharging the battery.
3.7 Mechanical Requirement
3.7.1 Composition
The UPS no switch is a 600 mm wide cabinet with no switch option. The UPS single switch contains the cabinet of 600 mm
width, which provides the maintenance bypass switch Q3. The UPS four switches contains the cabinet of 600 mm width,
which provides the rectifier input switch Q1, bypass input switch Q2, maintenance switch Q3 and output switch Q5.
3.7.2 Moving the cabinet
WARNING! The lifting equipment for moving the UPS cabinet must have enough lift capacity.
WARNING! The center of gravity of the UPS cabinet is high, avoid falling over during the cabinet movement.
WARNING! Vertical hanging of cabinet is prohibited.
The UPS cabinet presents a tipping hazard. Do not tilt the cabinet more than 15 degrees from vertical while transportation.
Ensure that the UPS weight is within the designated surface weight loading of any lifting equipment. See Table 12.3 on
page172 for weight of the UPS.
The Vertiv™ Liebert® APM2 UPS cabinet can be moved by forklift or other similar lifting equipment.
