7 Wiring and Connections
This section is provided for qualified personnel to install and interconnect the power components within the
Te25xh. Regarding battery installation, refer primarily to the manufacturer’s guidelines for more specific
information.
7.1 Grounding
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
Do not route AC and DC wiring in the same conduit.
7.1.1 Site Ground Wire Entry
Knockouts are provided on the bottom and rear of the enclosure for making the site external ground wire
connection.
7.1.2 Master Ground Bar (MGB)
The master (main) ground bar is located on the bottom right side of the enclosure. Terminate to the MGB and to
the external ground ring with either a compression or exothermic connection. Argus recommends a minimum #2
AWG wire size.
7.1.3 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.
