ROTECTION
The SunSaver is generally protected from reversed connec-
tions, but the system operator and other equipment will be at
risk when polarities (+ and – ) are reversed. Carefully check
before making each connection to be certain the polarity is
correct.
5.3 I NSTALLATION P ROCEDURE
N OTES :
• The SunSaver prevents reverse current leakage at night, so
a blocking diode is not required in the system.
• The connector terminals will accept a maximum wire size
of AWG #10 (up to 5.2 mm 2 ). A flathead screwdriver is
required. (Some #10 spade connectors may not fit in this
terminal.)
• Tighten each terminal clamping screw to 20 inch-pounds of
torque.
• The SunSaver is designed to regulate power from a PV
array. Other generators can be connected directly to the
battery, however, with no effect on the SunSaver.
• Do not connect any system wires (Solar, Battery, Load) to
the SEALED OR FLOODED SELECT terminal.
• The installation should follow the requirements of the U.S.
National Electric Code, Section 690.
• The installation should follow the requirements of the
National Electrical Code Article 501-4(b) and/or Canadian
Electrical Code Article 18-156 when installing a SunSaver in
a Hazardous (Classified) Location.
Refer to the connection diagram on page 5 to illustrate each of
the following installation steps.
1. Inspect the controller for shipping damage. If possible,
mount the SunSaver to a vertical surface.
Allow a minimum of 5 cm (2 inches) space above and below
the controller for air flow. Protect the controller from direct
sunlight or other heat sources.
The SunSaver can be mounted outdoors. Avoid mounting in
in direct rain such that water could collect under the cover. If
installed in an enclosure, some ventilation is recommended
to minimize operating temperatures.
