Step 3: Mark Holes
Use a pencil or pen to mark the four (4) mounting hole
locations on the mounting surface.
Step 4: Drill Holes
Remove the controller and drill 3/32” (2.5 mm) holes in the
marked locations.
Step 5: Secure Controller
Place the controller on the surface and align the mounting
holes with the drilled holes in step 4. Secure the controller in

3.4 Wiring
NOTE: A recommended connection order has been
provided for maximum safety during installation. When
disconnecting, solar input must be removed rst before
disconnecting battery. See caution below.
NOTE: The SunSaver is a negative ground controller.
Any one negative conductor can be earth grounded as
required. Grounding is recommended, but not required
for correct operation.
NOTE:
To comply with the NEC, the SunSaver must be installed
using wiring methods in accordance with Article 690 of
the latest edition of the National Electric Code, NFPA 70.
NOTE:
The total current draw of all system loads connected
to the SunSaver LOAD terminals cannot exceed the
controller’s load current rating.
NOTE:
For mobile applications, be sure to secure all wiring.
Use cable clamps to prevent cables from swaying when
the vehicle is in motion. Unsecured cables create loose
and resistive connections which may lead to excessive
heating and/or re.
WARNING:
EXPLOSION HAZARD - DO NOT DISCONNECT WHILE
CIRCUIT IS LIVE UNLESS AREA IS
KNOWN TO BE NON-HAZARDOUS.
AVERTISSEMENT:
RISQUE D’EXPLOSION. NE PAS DEBRANCHER TANT
QUE LE CIRCUIT EST SOUS TENSION, A MOINS QU’lL
NE S’AGISSE D’UN EMPLACEMENT NON DANGEREUX.
CAUTION: Unit has no battery removal protection.
Disconnecting battery during charging may cause a brief
spike in load voltage (above the 15V regulation limit)
which may damage sensitive equipment.
