Figure 101. External control wiring plate.
m) For bottom entry of external low voltage conductors, there
are two removable cover plates on the floor of the front of a
vertical section . For any foundation method it is the respon-
sibility of the customer to provide a suitable means to seal to
prevent escape of arc products or accommodate the escape
of arc products through the cutouts made in the cover plates.
Sub-paragraphs a and b following are suggestions for two
commonly encountered foundations .
1. For switchgear installed on a concrete slab foundation,
conduits are typically installed prior to the switchgear being
set in place . For this situation, it is recommended the
cover plates be cut to clear each conduit, reinstalled and
sealed with caulk around the perimeter of the conduit, and
around the wires or multiple conductor cables entering
each conduit.
2. For switchgear installed on a steel floor, conduits may
be installed prior to installation of the switchgear or after
switchgear is installed. In this case, it is recommended the
same procedure be followed as described in paragraph l)
for conduits, jacketed multiple conductor cables, or bundled
unjacketed conductors.
5.12 Installing cable adapters
Cables are connected to the tank bushings using medium-voltage
separable connectors, connected to the cables.
The cables must be restrained to prevent movement in the event of
short circuit conditions. Cable cleats and cable compartment cable
bracing are used to fix the cables in place.
Eaton DTS1242 and DTB1242 cable adapters can be used on XGIS
switchgear. Other cable adapters are also applicable, and can be
applied once their suitability has been determined.
DTS1242 are used for one cable per phase. If more than one cable
per phase is required, a combination of DTS1242 and DTB1242 cable
adapters are used.
Surge arresters can also be applied to cable bushings. When surge
arresters are required, the cable bushing will accommodate a
maximum of two output cable adapters and the surge arrester.
Detailed installation instructions for Eaton cable connectors type
DTS1242 and DTB1242 can be found in installation manuals
MN650023EN and MN650024EN, respectively.

5.12.1 Cable T connectors
Cable T connectors couple the tank output bushings to output
cables. Their design permits further coupling of additional connectors
(companion connectors) to the T connectors when parallel cables are
needed.
