Electrical Connections
The following electrical connections are required in the field:
• Controls (user interface, Network Management Card)
• Communication (A-Link, Building Management System)
• Power
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.
WARNING
ELECTRICAL HAZARD
Potentially dangerous and lethal voltages exist within this unit. More than one disconnect
switch may be required to energize or de-energize this equipment. Observe all cautions
and warnings. Failure to do so could result in serious injury or death. Only qualified
service and maintenance personnel may work on this equipment.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
CAUTION
ELECTRICAL HAZARD
• Three-phase (plus ground) electrical service is required. Electrical service must conform
to local and national electrical codes and regulations. The equipment must be grounded.
Check the nameplate for correct Full Load Current and Minimum Disconnect Size.
• Before making any electrical connections, make sure that the unit is turned off and
locked-out. Lockout/tagout represents safety procedures that remove access to a device
and physically labels the device as intentionally out of service.
Failure to follow these instructions can result in equipment damage.
