: Angles are marked on the bracket of the solar panel (0° - 90° tilt).
Connecting the Power Supply / Charge Controller
Power supply/solar panel wires enter the enclosure through the side or bottom conduit entry (Figures 2.5
and 2.6). Refer to
for size and location of the conduit entry. The charge
controller is integral to the main board.
See Figures 2.7 through 2.9 for reference to various installation types.
for information about installation in a hazardous location.
Integral Charge Controller
For installation in Class I, Division 2 hazardous locations, the charge controller/power input are integral
to the Scanner 1141 main board.
CAUTION
This caution is only applicable when a battery is connected to terminals 2 & 3 (BATT
+
&
BATT
-
)
The power supply must be current limited to 10 Amps maximum and also be short circuit
protected.
All solar panels are short circuit capable and can therefore be used with the 1141, provided they do not
exceed 10 Amps.
In normal operation the 1141’s charging module will allow electrical current to flow to the battery
unrestricted. The amount of current flow will vary depending on size of the battery and present charge
level (voltage) of the battery and the voltage of the power supply.
