5. PAD MOUNTING
5.0.1 Perform the following procedure to pad mount the MESA® SOLE cabinet.
Step 1: Refer to Section 5.1 , "Concrete Foundation Pad Construction," Page 14
for recommended concrete pad construction.
Step 2: Clean all litter from the foundation pad surface.
Step 3: Dress the cable/conduit so that it will easily enter the cabinet splice
chamber as it is being lowered onto the foundation pad.
Step 4: Remove the anchor bolts and washers from the foundation pad. Set the
hardware aside to attach the cabinet to the pad.
Note: The conduit has a turning locking nut and bushing already
in place. The turning locking nut and bushing aid in aligning
and securing the conduit to the junction box.
ALERT
During lifting, the cabinet must be lowered so that the cabinet is level and parallel to
the pad surface. Place the cabinet so that it lines up with the anchor bolts. Make sure
the cabinet is clear of the conduits in the foundation pad.
Step 5: Place the cabinet on the pad. Loosen the slings so that the full weight of
the cabinet is on the pad. Check to be sure the cabinet is properly lined
up on the pad.
Step 6: To secure the cabinet to the pad, install 0.5-13 (1/2-13) bolts with washers
and lock washers into the bottom flange. Tighten all bolts securely.
Step 7: When the cabinet is secured, remove the slings, the tagline, and the
lifting eyebolts. Replace the eyebolts with the nylon hex-head bolts
included in the cabinet loose parts package.
ALERT
If the cabinet will not be powered up for an extended period, place a heat source,
such as two 150W light bulbs wired in parallel inside the cabinet to prevent condensation.
5.1 Concrete Foundation Pad Construction

45.72 cm).
5.1.5 Use a minimum of six inches (15.24 cm) of sand or gravel as a base for the
foundation pad. This will level the location to accept the pad.
Refer to Fig. 10 for the arrangement and size of the reinforcing mesh and the
template in the form prior to pouring concrete.
Use a high-early strength concrete mix so the cabinet may be placed three days
following concrete pouring. Coarse aggregate used in the concrete shall be graded
from 3/4-inch (19 mm) to No. 4 only.
The compression strength of the concrete must be a minimum of 4000 psi as
determined by ASTM C39 test of compression strength of concrete cylinders.
The slump of the concrete shall be 2 (50.8 mm) to 4 inches (101.6 mm) as
determined using ASTM test method C143.
The arrangement of the reinforcing mesh and the template in the form prior to
pouring concrete is shown in Fig. 10.

8. HEAT EXCHANGER
8.0.1 The MESA® SOLE cabinet includes a door mounted heat exchanger which is
capable of removing 650 Watts of heat at 65o.
Fig. 13 : Door Mounted Heat Exchanger
8.1 Heat Exchanger Fans
8.1.1 The heat exchanger is a dual air chamber, vertical air flow device that keeps the
temperature within the equipment manufacturer’s recommendations. The
exterior cooling air is never mixed with the air in the electronics chamber.
8.1.2 The heat exchanger is equipped with an internal and external fan that can run
independently of each other. If one fan fails, the other will keep operating.
The external fan draws exterior air through the bottom of the cabinet and
exhausts it out into the air chamber in the cabinet top.
The internal fan draws interior air in from the top of the electronics chamber and
exhausts it out the bottom of the chamber.
8.2 Heat Exchanger Control
8.2.1 The MESA® SOLE heat exchanger system is managed by an Environmental
Control Card (ECC).
