3.0 Installation
3.1
Location
NEC article 700 EMERGENCY CIRCUITS should be referenced for proper installation of a
Central Inverter System. Article 700 dictates that unit must be mounted in a permanent
location. Choose a cool dry place with normal ventilation and one which will allow easy access
for testing and maintenance. Avoid a location which could allow vandalism and tampering with.
Avoid areas that would prohibit visual contact with the heads up LED status displays.
3.2
Operating Environment
Choose a location that is controlled between 20 and 30 degrees C. for optimum battery life
and performance. Lite-Minder is UL listed between 20°C to 30°C (68°F to 86°F) because of
battery discharge performance results. Do not install in a wet or damp location. Do not install
in environments that will expose the unit to excessive temperatures like boiler rooms as this
will significantly depreciate battery life.
Heat is the determining factor of battery life. Every means should be made to keep the
batteries in an environment that keeps the batteries around 25 degrees C for rated battery life.
3.3
Ventilation
Choose a mounting location that is clean and dust free. Do not install in areas where there is
particulate from heavy industrial machinery, corrosive chemicals or welding and plasma
cutting environments, etc.
WARNING – Batteries for Light-Minder can weigh up to 60 pounds
each. Total system weight can be up to 160 pounds. Ensure that the
mechanical mounting means can support this weight.

Mounting Guidelines
3.4.1
Clearance
Lite-Minder is convection cooled and air ventilation is through the sides and up the top. Leave
at least 4 inches of clearance on the sides and top for proper air circulation.
WARNING - Never leave any objects lying on the top of the unit which
would prevent proper air flow. This blocking of air circulation may
result in an over-temperature fault during Battery Charging or Battery
Power mode depending upon ambient conditions.
