3. INSTALLATION
3.1 Site & Environment Considerations
The main function of the ELI is to provide a safe, clean independent
electrical supply to the sensitive load so that it is free from any random variations,
disturbances or interruptions of the utility mains. The ELI also provides a
constant power which is perfectly regulated in both voltage and frequency. When
the mains are not available, the ELI provides optimal back-up time depending on
the battery bank capacity connected to it.
The life expectancy of the ELI is 10 years and greater. Batteries are not included,
because life expectancy of the batteries depend on the type of battery, the
temperature and humidity of the environment in which it is installed, and the type of
charger that is applied to the battery. Therefore 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 in considering
the site and environment of 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). If the ELI is installed indoors,
care must be taken to insure the evacuation of heat from a closed room will be
exhausted.
(b) Adequate space (at least 1M) should be allowed to open the door, and
unobstructed by other objects for operation or maintenance. Adequate space
(at least 1M) should be allowed at the top of the ELI, to assure heat dissipation
is ventilated through the openings.
(c) Do not put any objects on the top of the ELI that may obstruct ventilation. Do
not locate the ELI near any heat source, machinery which produce metallic
dust or powder, or any facility that will produce corrosive substances or
vapor.
(d) Protect the ELI from accidental damage from fire extinguishing (sprinkler)
systems. Protect the ELI from abnormal conditions with a dedicated cutoff
from the incoming power.
