Handling
The individual eTower modules require no special handling considerations since the weight
is such that two people can easily carry it in the box. The 12 module crates require a pallet
trolley to move and a forklift for loading and offloading.
The installation of the eTower is easily performed manually by two people.
4.1.4
Mounting
The first eTower module can be placed on the floor or a stand or shelf on its supplied
pedestal, with units stacked on top of it, each sitting on their own pedestal, see Figure 2.3
for an example of a system stacked with four modules. The eTower must be placed on a firm
level surface to ensure that the tower remains stable. The pedestal is designed to
comfortably withstand the weight of six eTower modules. Stacking more in a tower is not
recommended as the tower may become unstable.
Installation into 19” racks is made possible by ordering the angle brackets required from
Freedom Won. The eTower is exactly five standard rack units high (5U). Two brackets are
required per module.
If floor mounting on the pedestal is not suitable for a given application the eTower may also
be installed with the terminals facing upwards, preferably not directly on the floor, but on a
stand or shelf or wall mount bracket. Wall mount brackets are available from Freedom Won
on request, which must be ordered along with the 19” rack mount brackets, because they
are incorporated into the wall mounting system.
Ensure that the eTower is mounted at least 0.5m away from any heat source, and away
from direct sunlight in a dry cool area free of moisture.
5.
Environmental Requirements
No specific venting is required since the eTower emits no hazardous gases, however air
circulation may be required to ensure room temperature is maintained at reasonable levels,
preferably below 30
˚
C (see eTower warranty for information regarding upper temperature
limits for hot environments).
Room heating may be required in cold climates to keep the room above 0
˚
C, since charging
of the eTower is not permitted below 0
˚
C. Ambient environments that regularly exceed 35
˚
C
should employ room cooling if practicable to ensure optimal eTower service life.
Temporary storage or transport of the battery is permitted in the range -20
˚
C to 45
˚
C,
however extended storage longer than 60 days should be between 0
˚
C and 30
˚
C.
The eTower IP rating is IP20.
