STEP 1: Check Controller Limitations
Verify that the highest temperature compensated solar
array open-circuit voltage (Voc), and load current do
not exceed the ratings of the EcoPulse version being
installed.
STEP 2: Remote Temperature Sensor
WARNING: Risk of Fire.
If no Remote Temperature Sensor (RTS)
is connected, use the EcoPulse within 3m
(10 ft) of the batteries. Internal Temperature
Compensation will be used if the RTS is
not connected. Use of the RTS is strongly
recommended.
Connect the RTS to the 2-position terminal located
(see figure). There is no polarity, so the (+) or (-) can
be connected to either screw terminal.
WARNING: Equipment Damage.
Never place the temperature sensor inside
a battery cell. Both the RTS and the battery
will be damaged.
CAUTION: The EcoPulse will use the local
temperature sensor for compensation if the RTS
is not used.

Installation
STEP 3: Grounding
NOTE: Depending on the country of
installation, conductors identified by the
color green, or a combination of green /
yellow, shall only be used for earthing
conductors.
For safety, and effective lightning protection, it is
recommended, and may be locally required, that
the negative conductor of the charging system be
properly grounded. Use only one system earth
ground. For conductor sizing requirements, refer to
the U.S. National Electrical Code, or applicable local
regulations or code.
