WARNING: ELECTRICAL SHOCK HAZARD
Operate this equipment only when covers are secured. Servicing requires
access to live parts which can cause death or serious injury. Refer servicing to
qualified personnel. For safety and proper performance, this module must be
connected to a properly grounded three-wire source of electrical power.
Electrical connections must be made in compliance with National Electrical
Code (ANSI/NFPA 70) and/or any applicable national or electrical codes.
Two electrical connections are required on the Analyzer Module: POWER and NETWORK
(See Figure 2-4). On the Analyzer Module, two NETWORK connectors are available, either
of which is appropriate for: 1) interconnection with the Backplane of the Platform or 2)
"daisy-chaining" with other NGA 2000 components (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
connection is made, and that this is separate from the power return lead. Failure to ensure
a good ground may result in random noise and disturbance in the analyzer readings.
