4.5 POWER TERMINAL BLOCK WIRING DIAGRAM
Power connections to the LT1 are made using the 4 pin power terminal block. Once all connections
are made, the terminal block will be inserted into the terminal port to complete the cycle.

4.5.1 WIRING DIRECT TO BATTERY
If the LT1 is not being used in conjunction with a solar panel and regulator, follow these steps.
1)
Connect the positive wire to the PW pin and the
negative wire to the G pin.
2)
Connect the Power Ground (G) wire to the negative
pole of the battery (always connect this one first).
3)
Connect the Positive (PW) wire to the positive pole of
the battery.
4) Connect the Chassis Ground wire (CG) to the grounding system
5) Do not insert power terminal block at this time.
4.5.2 WIRING WITH A SOLAR PANEL AND SOLAR REGULATOR
Make power connections in accordance with the manufacturer’s instructions.
Follow the manufacturer’s directions for connecting the solar panel and
regulator to prevent any damage to the system.
4.5.3 GROUNDING THE LT1
An external earth ground wire MUST be attached between the earth grounding system and the CG
(Chassis Ground) pin to provide protection from lightning and other electrostatic discharge. Be
aware that the composition of the substrate directly affects the efficiency of the earth ground; areas
with a low conductive substrate such as rock, sand, ice may require more than one grounding rod.
