A.1 Line Reactor Installation Instructions
These instructions apply to the installation of the line reactor kit in a main supply panel. See the Spare
Parts Selection Guide for product specifications.
A.1.1 AC Line Cable Connection (From External Disconnect)
1. "Figure A-1 Line Reactor Connections" shows a schematic of the main input circuit and
connections to the line reactor. Use this schematic as a guide for choosing the location of the
line reactor.
2. Feed the AC line cable through the opening in the side of the main supply panel.
3. Attach the AC line wires to the line reactor terminals as shown in "Figure A-1 Line Reactor
Connections".
4. Attach the ground cable to the mounting block on the panel wall. Ensure there is good
electrical/mechanical contact between the ground cable and the panel wall.
5. Secure the AC line cable to the main supply panel using approved methods (e.g., cable gland).
A.1.2 AC Line Cable Connection (to Compressor Terminal)
1. Feed the AC line cable through the opening in the side of the main supply panel.
2. Attach the AC line wires to the line reactor output terminals as shown in "Figure A-1 Line
Reactor Connections".
3. If a harmonic filter is being installed, attach its AC line wires to the line reactor output
terminals.
4. Attach the ground wire to the mounting block on the panel wall. Ensure there is good
electrical/mechanical contact between the ground wire and the panel wall.
5. Secure the AC line cable to the main supply panel using approved methods (i.e., cable gland).
6. Refer to Section "20.7 Power Wiring" on page 105” for instructions on completing the AC
input connection to the compressor.
