Cooling System / Heat Exchanger
2.2.4.1
The Boxer‐30 cabinet features an active heat‐ex
change system that compensates for the effects of internal
equipment heat and external solar and temperature loading in
side the cabinet. At the core of the heat exchange system are
numerous aluminum fins on each “side” of a sealed divider wall
within the heat exchanger. The dual air‐path exchanger uses
one fan to blow cool outside air past the “exterior air side” fins
of the heat exchanger and to direct the heated air out the
screened holes on the sides of the fan cover. Conversely, a

second fan circulates warm inside air down past the “interior
air side” fins of the heat exchanger and blows cooled air back
through the main cabinet compartment.
2.2.4.2
The internal and external fans of the heat exchanger
are thermostat controlled. The internal heat exchanger fan will

AC Duplex & GFI Outlets for Installed Equipment
In the bottom‐right rear corner of the cabinet are two AC du
plex outlets (with a 1/2” fitting below one on the cabinet
exterior surface), for powering any customer‐supplied AC‐
powered equipment mounted in the cabinet. When an external
AC power source is connected to these outlets, AC power also
can be provided to the GFI convenience outlet in the lower‐left
front corner of the cabinet (to facilitate the installer's test
equipment powering), by installing the provided AC 3‐wire
cable.
2.2.6
Grounding and Bonding Center
Boxer‐30's grounding and bonding center is located on the bot
tom interior surface of the cabinet (Figure 13), close to the
front door. A ground plate is provided that contains eight sets
of ground posts and one copper ground lug, for cable and chas
sis/earth ground. Bond equipment/cables to the ground posts
per company practice, and connect a #6 AWG chassis or earth
ground wire to the ground lug. An Electro‐Static Discharge
(ESD) wrist‐strap jack is also located on the ground plate.
