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.
E3-MAC 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 E3-MAC 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.
