2-5 ELECTRICAL CONNECTIONS

NOTE

Electrical connnections must be made in compliance with National Electrical Code (ANSI/NFPA 70) and/or any applicable na- tional or electical codes.

Two electrical connections are required on the Analyzer Module: POWER and NETWORK (See Figure 2-4 above). On the Analyzer Mod- ule, two NETWORK connectors are available,

either of which is appropriate for: 1) intercon- nection with the Backplane of the Platform or 2) "daisy-chaining" with other NGA2000 compo- nents (A star connection is acceptable for LON lengths under about 10 meters.)

Connect a source of 24 V 5A DC power to the power inlet. Make sure that the ground connec- tion is made, and that this is separate from the power return lead. Failure to ensure a good ground may result in random noise and distur- bance in the analyzer readings.
