3.4 Wiring
NOTE: A recommended connection order has been pro-
vided for maximum safety during installation.
The controller will not be damaged regardless of the
sequence of connections.
NOTE: The SunSaver is a negative ground controller.
Any combination of negative connections 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 con-
troller’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
