17 NetShelter SX 24U Cabinet - Installation and Customization Manual

Ground the Cabinet

The doors, side panels, and roof of the cabinet are grounded to the cabinet frame. The doors are grounded with

quick-disconnect cables. The roof and side panels are inherently grounded through spring fingers.

Each cabinet should be bonded directly to a common ground using one of the designated grounding locations

(two M6 threaded inserts) at the top or bottom of the cabinet.

• Use a Common Bonding Network Jumper kit (for example, Listed [KDER] Panduit® RGCBNJ660PY or

equivalent).

• Use paint-piercing washers between the ground terminal and the cabinet frame, or remove the paint on

the frame under the ground terminals, per NEC NFPA 70 Article 250.12.

• Torque the screws to 6.9 N•m (60 lb-in).

• Do not ground one cabinet to another cabinet in a cascading style. Ground each cabinet directly to the

building ground.

DANGER

HAZARD OF ELECTRIC SHOCK

Connection of the cabinet to building Common Bonding Network (CBN) is required.

Failure to follow these instructions will result in death or serious injury.
