4. Installation
4.1. Site & Environmental Conditions
The designed function of the ELI is to provide a safe, clean and independent electrical
supply free from random variations, disturbances or interruptions of the utility mains. The
ELI will provide a constant power source, which is regulated in both voltage and
frequency. When the utility mains are not available, the ELI will provide optimal back-up
time depending on the capacity connected battery bank.
Usually the life expectancy of the ELI is 8 to 10 years. The optimal life expectancy of the
ELI can be achieved by careful consideration of the site and environment.
The following precautions and recommendations should be checked when considering
the site and environment for the ELI:
a. The ELI should be located in a place with adequate ventilation (refer to the
specification of the heat dissipation of the ELI). Should the ELI be installed in a sealed
room, care must be taken to ensure adequate heat evacuation is provided.

b. Void space is not required on all sides of the ELI system, but adequate space, a
minimum of 1m (3’), should be allowed for the door to open. Adequate space, a
minimum of 60cm (2’) [recommended 1m (3’)], should also be allowed at the top of the
ELI system to allow for proper heat dissipation and ventilated through the top openings
(optional ventilation booth is available upon request). Leave a minimum of 2 feet on
right hand side of ELI.
c. The battery banks require access to front only.
d. Do not place any objects on the top of the ELI that might obscure the ventilation. Do
not place the ELI near any heat source, or machinery, which may produce metallic
particles, dust or powder. Do not place the ELI near equipment that will produce
corrosive substances or vapor.
e. Do not place the ELI below the shower of a fire extinguishing system (optional drip
shield available). Abnormal conditions of the ELI should be protected by a cutoff from the
power supply.
f. The user is required to guarantee the temperature and humidity values of the site
into which the ELI will be installed meet the required and published manufacturer
specifications. The ELI should be installed within the range allowed by these
specifications. The ELI is capable of continuous normal operation within a temperature
range of 0°C (32°F) to 40°C (104°F). For optimal performance and reliability the
recommended environment temperature is best at 25°C, with humidity 0 to 95% non-
condensing.
g. The floor loading capacity should be sufficient to endure the weight of the ELI. Four
right-angled steel feet attached restrainers are included with the ELI system, which
should be inserted into the floor for securing the ELI system, when the location has the
potential to experience vibrations. (e.g.: earthquake, moving vehicles, or tanker.) The
locations and layout of the restrainers are shown below.
h. Walls, ceilings, floors or anything near to the ELI should be constructed of non-
