Pre-installation preparation
The permanent location of Recombiners must be on a smooth,
solid, and level foundation . Alignment is verified in the factory prior
to shipment .
An uneven foundation can cause misalignment of sections, units,
doors, and other parts .
If a housekeeping pad is used, check factory drawings and verify
handle height rules relative to the National Electrical Code (NEC
where applicable .
When embedded anchors or channel sills are used, materials
and attachments must be adequate to support the structure(s) .
Recombiner sections must be aligned and level over the length
of the installation .
From manufacturer's drawings, determine the layout of the
Recombiner equipment for each location . Verify and confirm
that the available equipment space and equipment location(s)
are in compliance with the minimum working space clearances
per the NEC .
Refer to the manufacturer's Recombiner drawings for available
conduit area in each section before installing the finished grade
flooring (see Figure 6) . Conduits must be installed in conduit
area shown to ensure compliance with NEC wire bending
space requirements .

Conduit areas may vary in each section of a multi-section
Recombiner lineup .

N
otee:
The preferred method of anchoring the Recombiner is by fastening
the Recombiner to steel channels that are properly and permanently
embedded in a concrete floor or by using anchors designed for
this purpose .
Conduits, floor, and/or wall openings or other penetrations, should be
located relative to the space shown on the manufacturer's drawings .
Refer to the National Electrical Code for installations in damp
locations for additional requirements .
The entire area around the Recombiner should be thoroughly
cleaned of all debris .

Considerations for
seismic qualified installations
Recombiners are "seismic qualified" and in seismically active areas
require additional considerations . Because electrical equipment is
installed as part of a system, pre-engineering layouts are critical in
seismic applications .
Eaton Recombiners are marked as "seismic qualified, " and anchoring
the Recombiner is critical in seismically active areas . Experienced
engineers in seismic requirements should select methods and
techniques of attachment and tested anchoring systems . Embedded
concrete anchors or steel attachments must be adequate to resist
the forces established by the local building code . Bolts of the proper
grade of steel must be correctly sized and torqued . The embedded
anchors must be correctly installed in accordance with the method
specified by the anchor manufacturer . Refer to seismic instructions
in TD01508002E provided by Eaton for more information .
Conduit layout in concrete for loads entering and/or exiting the
bottom must be designed and installed to prevent damage from
an earthquake . If top entry is necessary, seismic fittings or flexible
conduit is needed .
Consult applicable local building codes and regulatory agencies for
other specific requirements for seismic installations . Contact Eaton
for additional information .
Installation
Use caution and appropriate equipment and practices when moving
Recombiner into its final position .
WARNING
RECOMBINER IS TOP-HEAVY. USE CARE IN HANDLING.
Determine the Recombiner orientation with the use of
manufacturer's drawings and markings on the Recombiner sections .
Recombiners may be shipped either in individual sections or in
two or more sections joined by the manufacturer (see Figure 7
and Figure 8) .
