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. 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 °C for optimum
battery life. LM/LMOPT Series is UL924 listed between 20 and 30 °C due to
the battery discharge performance results. Colder temperatures decrease
the batteries discharge duration (90 Minutes is required per UL924 and NEC
Article 700) and warmer temperatures will adversely affect battery life. The
optimal temperature of the LM/LMOPT Series system will be 25°C / 77°F and
all measures should be made to keep the batteries in this temperature zone.
Temperature -vs- Life expectancy is shown below.
