Installation Of Traveling Crane; Extension Of Existing Switchgear; Extending Indoor Switchgear; Extending Outdoor Switchgear - Siemens WL Series Instruction & Installation Manual

Type WL Low Voltage Metal-Enclosed Switchgear
Installation
If the lineup consists of more than one shipping section, each
successive shipping section should be installed in the similar
manner. Move the second section into place, being certain
that the front panels are aligned with those of the first section.
Check for plumb as was done for the first section. Insert hard-
ware for bolting the two sections together, but do not tighten.
Repeat the leveling, shimming and tightening of anchoring
hardware as on the first section. After this is complete, tighten
the hardware holding the two shipping sections together.
Repeat this procedure for each shipping section in the lineup.
Check the supports to be sure that no shipping split (junction
between two shipping sections) is unsupported. If proper
support is not present, correct as needed.
Install roof channels as shown in Figure 13.

Installation of Traveling Crane

Heavy weight.
Can cause death, serious personal injury or
property damage.
Install traveling crane per the following instructions
and tighten all hardware.
The traveling crane is furnished as standard equipment on
walk-in outdoor switchgear, and is shipped installed.
For indoor switchgear installations, the traveling crane is an
optional accessory. When this option has been ordered, the
crane is shipped loose with the accessories. To mount the
crane, it is necessary to remove the stop angles from one
end of the track, roll the crane onto the track, and reinstall
the stop angles. See Figure 14.
Important: Be sure that the crane is properly lubricated before
use, as outlined in the "Maintenance" section of the manual.

lineups. The main bus has been terminated with tin-plated
aluminum of silver-plated copper pads with the necessary
holes to splice to the new installation.

Extending Indoor Switchgear

To extend indoor switchgear, remove the end plate, line up
and anchor the new equipment, as covered in the first part
of this instruction book, make up the primary and secondary
connections, and mount the end plate at its new location.

Extending Outdoor Switchgear

Before extending the length of outdoor switchgear a new
section of foundation should be installed and ready, with
anchoring studs and the required conduits in place.
To expand outdoor switchgear, remove the existing end roof
channel and the end plate from both aisle and vertical section.
It also will be necessary to relocate the aisle door panel (mounted
in the aisle wall) and replace it with a new aisle wall panel which
will be shipped with the new equipment. Align the new switch-
gear with the existing lineup, using the same procedure as
discussed earlier in this section.
Tighten the anchoring hardware. Make up primary and second-
ary connections. Relocate the aisle wall door panel to the end
of aisle and install the new aisle panel. Install the roof channels
at the split between the existing and new sections. Remount
the end plates and reinstall the end channel.
