Operations And Maintenance Manual
DC Power Connection
Before installing the power connection to the unit, the installer must first insure that the DC power source
is in the range of 10-30VDC and is capable of providing 8 watts of power to the unit. Although the
StrataBox Sensor unit is reverse polarity and over-voltage protected, it is always required that the power
mains be turned off during system wiring for both personal and equipment safety.
The Power Cable supplied with the system is 10 feet long, and includes 3 conductors. The wires in the
power cable must be connected as follows:
RED
– Positive DC Voltage (Fused Lead), DC IN+
BLACK
– DC Return, DC IN-
WHITE
– Earth Ground, SHLD
The Positive DC Voltage lead includes a 3 Amp in-line Fuse. In the unlikely event that the fuse is blown
it should be replaced with a fuse of the same amperage. Installing an incorrect fuse can result in damage
or fire to the unit if it is not operating properly.
The Power Connector on the Sensor Unit is shown below in Figure 2-6.
Figure 2-6 StrataBox Sensor Power Connector
Electrical wiring standards require that the StrataBox Sensor Unit be properly attached to a solid chassis
ground via the ground stud on the bottom of the unit, or the Earth Ground wire (WHITE) in the power
cable. When connecting to the ground stud, a tinned copper braided wire (0.190 gauge or greater) is
recommended.
NOTE: Connecting the Earth Ground is required for optimum system performance and
safe operation. The white wire in the power cable OR (BUT NOT BOTH) a ground
wire to the unit ground stud is needed. Connecting both the white wire and the
ground stud to earth ground may degrade performance due to induced ground
loops.
