3.3 System Working Environment Checking
3.3.1 Cleaning
Before installing and switching system power on, the dust and iron scurf must be removed to keep
a clean environment.
The system cannot be installed in a desert area without an enclosure to protect it from sand.
Danger:
Each Battery module has active DC power at its terminal all the time, be careful when
handling the modules.
3.3.2 Ventilation
AXIstorage Li SV1 system
’
s working temperature range: 0
℃
～
50
℃
; Optimum temperature: 18
℃
～
28
℃
.
There are no mandatory ventilation requirements for the battery modules, but please avoid
installations in confined area. The aeration shall avoid high salinity, humidity or temperature.
Caution:
The AXIstorage Li SV1 system has IP55 protection. But please avoid frost or direct sunlight.
Conditions out of the working temperature range will cause the battery systems over / low
temperature alarm or protection trigger which further leads to cycle life reduction. If it is necessary
due to the environment, a cooling system or heating system should be installed.
3.3.3 Fire-extinguisher System
It must be equipped with fire-extinguisher system for safety purpose.
The fire-extinguisher system needs to be regularly checked to be in normal condition. Refer to the
using and maintenance requirements and please follow the local fire equipment guidance.
3.3.4 Grounding System
Before installing the battery make sure the grounding point of the basement is stable and reliable.
If the battery system is installed in an independent equipment cabin (e.g. container), make sure
the grounding of the
cabin is stable and reliable.
The resistance of the grounding system must be
≤100mΩ
3.3.5 Clearance
Minimum distance to heat sources is more than 2 meters. The minimum distance to another
battery module(rack) is more than 0.5 meters.
3.4 Handling and placement
Warning:
The battery pile’s power terminals are
under high voltage DC. It must be installed in a
restricted access area;
Warning:
AXIstorage Li SV1 is a high voltage DC system, operated by qualified and authorized
personnel only.
3.4.1 Handling and placement of the battery modules
A single battery module weights 36kg. Without handling tools, it must be handled by at least 2
persons.
