Electrical Connections
The following electrical connections are required in the field:
• Controls (user interface, Network Management Card)
• Communication (A-Link, Building Management System)
• Power
NOTE: All electrical connections must be in accordance with local and national codes and regulations.
See the equipment nameplate for voltage and current requirements.
All low-voltage connections, including data and control connections, must be made with properly insulated
wires. Low-voltage wiring must be insulated based on the wiring with which it is routed. Wiring does not require
300-V insulation if it is separated from line voltage wiring. However, it will need 600-V insulation if it is wired in
the same cable tray as 480-VAC wiring.
