Rack Mount Frame Assembly and Installation

User Line Connector

The user-line is a 6-position wire clamp connector adjacent to the DC input connector. Table 2-1 lists user functions and associated terminal numbers.

User Line Wiring

Use twisted pairs of 22-24 AWG for connections. Before making any connections, ensure power to the rack has been disconnected. Carefully route the wires away from high power load cables to minimize noise effects on signal integrity.

User Line Connection

Use this table to wire appropriate signals.
