INSTALLATION INSTRUCTIONS
1. Before beginning electrical installation, disconnect all positive and negative AC and DC power sources.
2. For optimal performance, mount the charger vertically, in a well ventilated location.
NOTE: The charger should be located near the batteries to minimize wire length and its associated voltage drop to
maximize charging efficiency. If the batteries are not close together, place the charger near the battery connected to
the Start Battery stud. Never place charger directly above or below battery being charged.
3. Remove the DC termination cover by lifting the tab on the right hand side.
4. Route DC wires from each charger output to battery fuse holder. See Installation Diagrams on pages 7 and 8.
All wiring should be of sufficient length to allow proper routing, support, drip loops, service loops, and termination.
Strain relief for wiring should be installed near the charger to prevent loosening of connections with vibration or
shock. Fuses should be installed at the battery positive connections to prevent battery power from feeding back
into a fault in the wiring, or in the battery charger. See Wire Size And Fuse Rating Table on page 5 for recommended
fuse values. Best practices dictate that every positive wire on the boat, outside the engine starting circuit, must
have circuit protection. Please follow all local and national electrical standards, codes, and regulations for
installation and wiring.
5. Route the AC supply cord from the charger to the AC panel, and terminate at the appropriate AC circuit breaker. Leave the
breaker in the “off” position.
NOTE: Connect AC wiring, but do not energize the circuit until AC wiring is properly covered, DC is connected, and DC fuses
are installed.
6. Recommended Connection [Battery Temperature Sensor]: Attach the battery temperature sensor to the largest
battery using the supplied adhesive pad. If both batteries are the same size, attach to the battery with the most
loads. Attach the sensor in the center of the long side of the battery. If multiple batteries are in a battery bank,
attach the sensor in the center between multiple batteries. When external circumstances could create a significant
difference in temperature on one side of a battery versus another, always attach the sensor on the warmest side.
NEVER pierce the battery casing with a screw or other fastener. Extend sensor wires as necessary to reach the
charger using appropriate fully insulated butt connectors or a terminal block with insulating cover.
7. Optional Installation [Remote LED Bezel]: Drill a 7/16" [11mm] hole through a flat mounting surface in a
visible location. Clean and dry the surface around the drilled hole for best adhesion of the bezel. Remove the
adhesive backing liner from the bezel, thread the LED wires through the hole, and push the bezel securely into place
against the mounting surface. Extend the LED wires as necessary using appropriate fully insulated butt connectors
or a terminal block with insulating cover. Connect the positive (red) wire from the LED to your battery positive
terminal through a 2A fuse at the battery. Place this connection on top of all current carrying conductors. Connect
the negative (yellow) wire from the LED to the charger Remote LED terminal.
8. Optional Connection [Start Isolation-protects sensitive electronics from voltage drops and spikes during
engine start]: Connect the Start Isolation terminal of the charger to the “start” position of your engine’s ignition
switch, or another connection point that has positive voltage applied only when actively cranking your engine. Install
a 2A fuse at the point of connection to positive voltage.
9. Optional Connection [Manual Combine-emergency jump start if start battery is low]: Connect the Manual Combine terminal
of the charger to one contact of a single-pole / single-throw (SPST) switch. Switch not included. Suggested switches are
Blue Sea Systems PN 8292 (momentary) or 8282 (non-momentary). Connect the other contact of the switch to your
battery positive terminal through a 2A fuse at the battery. Place this connection on top of all current carrying conductors.
10. Install appropriate DC fuses (see Wire Size And Fuse Rating Table on page 5).
11. Confirm all connections are correctly installed per Installation Diagrams.
12. Secure the termination cover back over the connected wires.
13. Restore AC power and turn on the AC supply circuit breaker to the battery charger.
