Electrical Installation

This section explains how to hook-up your Calc-An-Acre II to a 12VDC power connection.
The Calc-An-Acre II must be connected to a 12VDC negative ground electrical system.
ROUTING HARNESS AND CABLING
Avoid ar eas where the ca ble may be sub ject ed to abra sion or exces sive heat.
WIRING HARNESS ORIENTATION
Wiring with multiple branches must be installed so that the individual wires point downward, as shown. This will protect the
internal connections from exposure to liquid chemicals.
WRONG
POWER CONNECTION
Locate the power cable lead on the Calc-An-Acre II harness and route to a switched +12VDC source. At tach the BLACK wire
to ground. Connect the RED wire to positive terminal. If using an unprotected circuit as +12VDC source, add a 2A inline fuse
(not included in kit.)
Alternately, the Calc-An-Acre II can be powered directly from the battery along with a power switch (not included in kit.)
Note: Ensure clean metal-to-metal con tact from wiring to terminals.
Calc-An-Acre II is equipped with a non-volatile memory which does not re quire a con stant supply of power to retain daily
totals or calibration val ues.
