Page 2: Safety Information
Important Safety Instructions Please save these instructions. This manual contains important safety, installation, and operating instructions for the charger. The following symbols are used throughout the manual to indicate potentially dangerous conditions or important notes. Indicates a potentially dangerous condition. Use extreme caution when WARNING performing this task. - Page 3 Ensure secure location where it cannot tip or fall For installation on boats: if the electrical devices are incorrectly connected, this can lead to corrosion damage on the boat. Verify installation with a qualified electrician or installer. Lay cables so they cannot be damaged by doors or be a tripping hazard. Damaged cables can lead to serious injury Use ductwork or cable ducts if necessary, to lay cables through metal plates or other panels Do not lay AC and DC cable in the same conduit and do not pull on the cables.

Page 10: Wiring And Fusing
Wiring and Fusing Battery Ring terminals are recommended for 12V input and output connections. The following is a reference incorporating a critical 0-3% max voltage drop and may not cover all unique applications that may exist. When the battery charger is sending the rated amps, the input side may experience a draw higher current draw by a factor of up to 50%. -

D+IGN Wiring to Ignition Circuit ALTERNATOR ANL FUSE ANL FUSE DC INPUT (STARTER) DC OUTPUT (HOUSE) CHASSIS GROUND CHASSIS GROUND DC Output Wiring (House) Only use 12V batteries. Damages due to connecting higher voltage batteries will not WARNING be covered in warranty. The DC-DC output will connect to the 12V auxiliary or house battery that you are intending to charge. -
Page 12: Dc Input Wiring (Starter)
counterclockwise clockwise DC Input Wiring (Starter) The DC-DC will not power on or operate until the D+ ignition cable is connected. NOTE When connecting the DC input, note that the DC-DC will still be off until the D+ ignition cable voltage senses. The DC-DC input will connect to the 12V starter battery that will be used to charge your auxilia- ry or house battery. -
Page 13: D+ Ignition Wiring
counterclockwise clockwise D+ Ignition Wiring The D+ terminal will be located on the output side but connects to the DC ignition circuit of the input starter battery. This may be in the engine bay fuse block for some vehicles. Refer to your own vehicle’s electrical diagram for D+ wiring placement. May require splicing or cable adjustments to connect correctly to your ignition circuit. - Page 14 The DC-DC will not power on or operate until the D+ ignition cable is connected to the ignition circuit where it will detect a 12V source to operate ON. The purpose is to toggle the DC-DC switch on when the vehicle is running with the alternator to prevent the DC-DC from operating incorrectly with just the starter battery leaving you with a drained starter battery.

Page 17: Setting Lead Acid
DIP Switches The 5 x dip switches can be configured to charge lead acid or lithium batteries. Note that ON is position down and OFF is position up if facing the dip switches directly. Lead acid profiles have an absorption charge and a float charge whereas lithium batteries will only have an absorption charge and no float charge. -
Page 18: Setting Lithium
Setting Lithium To get started, make sure SW5 = OFF to gear the charger for lithium batteries. There will not be a float voltage and instead users will select between Type 1 lithium voltages or switch into Type 2 lithium voltages depending on your lithium battery specifications. You must select a lithium Type to when selecting your charge voltage. -
Page 19: Battery Charging Logic
Battery Charging Logic Bulk Absorption Float 100 % 10 % Bulk (Phase I) (Lead Acid + Lithium) In the beginning, a discharged battery will be charged with maximum current and voltage will be climbing steadily until reaching the absorption voltage setpoint. Absorption (Phase U0) (Lead Acid + Lithium) The battery reaches the absorption voltage setpoint and holds the voltage constant while the current gradually decreases until the battery is becoming full (within 10-20%). -
Page 20: Troubleshooting
Troubleshooting If the DC-DC is not functioning correctly, it may be undergoing an internal electronic protection and stop normal operation. This is not indicative of a defective unit but may require some troubleshooting to resume normal operation. Electronic Protection Behavior Protection Troubleshoot Steps 1.Use a multi-meter to measure the DC input and DC output... - Page 21 Behavior Protection Troubleshoot Steps 1.Double check that your wiring is correct with a multi-meter and that the battery levels are suitable within the operating voltage range 2. Observe the ambient temperature. Avoid installations in direct sun. Ambient temperatures above 122°F/50°C will cause the High unit to stop functioning until conditions get cooler.

Page 22: Maintenance
Behavior Cause 1.Inspect your connections for tight, secure, and undamaged wiring to and from the DC-DC Connection 2.Check fuses for any breaks and replace them to continue break normal operation. 3.Use your multi-meter’s (check with manufacturer) continuity test to individually check each line (positive and negative) at the input and output to verify consistent connection. -
