drawer. (The connector bus must be reconfigured for use with 6V batteries.) The drawer is equipped with a set of
eight connectorized battery cables.
A battery heater tray is factory installed in the floor of the battery drawer. It is turned on automatically when the
drawer temperature decreases to 40°F (4°C), and remains on until the temperature increases to 60°F (16°C).
The battery drawers slide out for access to all batteries. The drawer has heavy gauge steel in load-bearing areas,
and is equipped with heavy-duty slides.
The SPX-CABFIN cabinet may be equipped with a Lorain Battery Thermal Management (BTRM) System. This
system is made up of an Alarm and Control Unit (ACU) mounted in the main equipment chamber, and Thermal
Sensing Units (TSUs) attached to each battery negative terminal and wired to the ACU. The TSUs open at the
temperature marked on the unit, typically 140°F (60°C); if this occurs, the ACU reduces the rectifier output to
-48 Vdc and generates a latched alarm.

ELECTION
Consider the following when deciding on the SPX-CABFIN cabinet location:
Right-of-Way
It should be the practice of any installing company to acquire, in advance of construction, rights-of-way from
landowners, and permits or other approvals from public authorities. It is recommended that SPX-CABFIN
cabinets be placed in servitudes, on dedicated (recorded) easements, or on property owned by the company; avoid
unrecorded easements.
Public safety road and street rights-of-way should be used only when there is adequate space to place the closure
and provide safe working conditions. The cabinet should be easily accessible with adequate parking to ensure
safety for personnel and vehicles. Also, place the cabinet where it will not create a visual or physical obstruction
to vehicular or pedestrian traffic.
Vulnerability
Select locations that will minimize accidental damage or vandalism. Consider the use of protective posts when the
cabinet is located where vehicles may run into it. Do not place the cabinet in a ditch or an area subject to flooding.
The cabinet should always be located on a site above the 100-year floodplain, and should not be subject to water
run-off or flash flooding during heavy rains. Do not place the cabinet in an area where the pad is subject to vehicle
loads. In regions subject to frost, the site chosen must be free of heaving.
