4. INSTALLATION
4.1. Installation Location Environment
The location of the battery should be in accordance with the operating temperature range and IP rating
specied in the Specication section of this manual. Although the batteries run at a low temperature, proper
airow around the batteries is recommended.
When installing the set, the following conditions should be met:
Please DO NOT install the product in a completely closed area with no air-conditioning. It can overheat
and cause a re.
DO NOT place in direct sunlight or near a source of heat. This can cause deformation, a breakdown, or a
re. Pay extra attention when you place the system near windows.
The battery should not be set where excessive oil smoke, steam, moisture or dust is contained in the air.
Ensure that the batteries are installed in a clean environment with minimal dust.
Avoid installing the set near the ocean. If unavoidable, appropriate air ltration should be used to
prevent salt air in contact with the batteries.
For proper air circulation to dissipate heat, allow a clearance of approximately 30 cm to the sides of the
battery.
DO NOT install the set near heat sources.
If the batteries are being installed in areas of extreme humidity levels, take the following precautions:
A humidity control agent must be placed inside the enclosure, with controlled airow to expel moist air,
and/or the system can be installed in a proper room with humidity control.
The SSLB1 battery is well-designed to be installed in a 19-inch cabinet. A suitable IP54 or above enclosure
must be used if the battery is installed outdoors.
