1027144–0001 Revision D 3–2 Installing indoor RT equipment
RT installation
If the RT IDU will be mounted in a rack, the rack must be
grounded, as shown in figure 3-1:
1. Run a ground wire from the rack location to the master
ground bar in the equipment room. This wire must be No. 2
AWG, green, stranded, and shielded.
2. Ground the rack by connecting a No. 6 AWG wire from the
rack to the No. 2 AWG ground wire.
Use a 2–hole lug to connect the No. 6 AWG wire to the
rack. Remove paint and apply anti–oxidant as shown in the
illustration.
