3.4 Installation

3.4.1 Inventory of items

Thoroughly inspect the packaging upon receipt of goods. If there is any item that is missing or if there is any damage to the external packaging or to the unit itself upon unpacking, please contact the supplier immediately.

3.4.2 Installation Location

Make sure that the installation location meets the following conditions:

• The installation site must be suitable for the size and weight of the battery.
• Must be installed on a firm surface to sustain the weight of battery.
• The area is water proof.
• There are no flammable or explosive materials in proximity.
• The ambient temperature is within the range from 0°C to 45°C.
• The temperature and humidity is maintained at a constant level.
• There is minimal dust and dirt in the area.
• Installation must be vertical or tilted backwards by maximum 15° – avoid forward or sideways tilt.

3.4.3 Wall-mounted

  measures may replace batteries and supervise operations. Unauthorized persons must be kept well away from the batteries.

• Verify that no voltage between the battery terminals and the ground is present before
  maintenance or repair. In this product, the battery circuit is not isolated from the input voltage.

• Hazardous voltages may occur between the battery terminals and the ground.

• Batteries may cause electric shock and have a high short-circuit current. Please remove all
  wristwatches, rings and other metal personal objects before maintenance or repair, and only use tools with insulated grips and handles for maintaining or repairing.

• When replace the batteries, install the same number and same type of batteries.

• When replace the parallel batteries, make sure the new battery is full charged

• Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes.
  It may be toxic.

• Please replace the fuse only with the same type and amperage in order to avoid fire hazards.

• Do not disassemble the battery system.
