DANGER
An enclosure that is not properly grounded can present an electrical hazard.
A proper grounding system that meets or exceeds the specifications of the equipment must be designed
and installed prior to or in conjunction with the construction of the mounting scenario. The ground system
must be bonded to the enclosure to ensure a “Common” or “Single-Point” Ground; some examples are:
New builds – Buried ground ring with bare solid conductor to ground rods.
Rooftop – Connection to building steel, water pipes, etc.
Refer to local codes and practices from the local power company. Size to suit.
Only a licensed electrician should connect any AC power and grounding to the enclosure. A dedicated
ground rod is required for the grounding the AC panel.
CAUTION
AC and DC wiring are not to be routed in the same conduit.
5.1 Master Ground Bus (MGB)
The master (main) ground bus is located at the bottom front left of the equipment rack inside the
equipment compartment section of the enclosure.
Terminate to the MGB with a 2-hole lug and to the external ground ring with either a compression or
exothermic connection.
5.2 Enclosure Chassis Ground (Factory Installed)
The chassis ground is connected to the enclosure frame and equipment racks and is terminated to the
MGB within the enclosure.
5.3 Site Ground Connection
Located on the outside of the enclosure, is an entry/exit point for making the site external ground wire
connection.
