Grounding
WARNING: Electrical Shock Hazard
Each cabinet must be connected to the Common Bonding Network (CBN) separately – do not daisy-chain. Do not use the
cabinet without an earth ground connection.
1. There are four 16mm cable entry holes in the bottom of the cabinet frame
(one in each corner)
. Select the location
that is most appropriate for your installation, remove the plastic plug, and route the ground wire
(not included)
up
through the hole from below the cabinet.
NOTE: Select the ground wire conductor size based on guidance from national and local electrical codes and install
according to those codes.
2. Attach the ground wire to the cabinet frame as shown below using the included M6 copper screw. Be sure to
install the included paint piercing washer between the ground terminal and the cabinet frame, or alternatively
remove the paint on the frame under the ground terminal, as per NEC NFPA 70 Article 250.12.
3. Torque the screw to 8 N-m (70 lb-in).
4. Place the included yellow ground symbol label on the cabinet frame next to the ground location.
