Installing the Enclosure
Pole-Mounting the Full-Size and Compact 7-Pin Enclosures
Figure 3.1 SEL-734B Required System Grounding
In cabinets with a ground lug, the ground lug is bonded to the chassis ground
of the SEL-734B and all metal parts in the cabinet. The ground lug is not
bonded to system neutral (see note). It is vital that the cabinet ground be
connected to the local ground conductor through use of local utility practices.
Pole-Mounting the Full-Size and Compact 7-Pin
Enclosures
The Full-Size Enclosure may be ordered with a factory-installed pole-
mounting bracket. The pole-mounting bracket for the Compact 7-Pin
Enclosure is available as an accessory. Figure 3.2 and Figure 3.3 show the
front view of the enclosure with the optional pole-mounting bracket attached.

NOTE: In some full-sized enclosures
and some older compact connectorized
enclosures, the ground lug is bonded

cabinet provides the correct ground-
to-neutral connection, or separation,
as required by your systems design.
