4.3 Installation Considerations
Although the eFlex is IP65 rated, if it is to be installed outdoors it is recommended that the
installation location meet the following conditions:
✓ At minimum, the eFlex should be protected from inclement weather with a cover/enclosure.
✓ The area is completely waterproof.
✓ The floor is flat and level (Inclination < 15°).
✓ There are no flammable or explosive materials.
✓ The optimal ambient temperature is within the range from 59 ℉ to 95 ℉.
✓ The temperature and humidity are maintained at a constant level.
✓ There is minimal dust and dirt in the area.
IMPORTANT NOTE: If the ambient temperature is outside the operating range, the battery
pack may stop operating to protect itself. Frequent exposure to harsh temperatures may
deteriorate the performance and life of the battery pack.
✓ All battery cables and their connections should be tight, intact, and NOT broken or frayed
✓ Check torque on terminal bolts
✓ Replace any damaged batteries and cables
