I. INTRODUCTION
The microprocessor-controlled Max
Charge MC-612 is the most advanced
regulator available. Designed to continu-
ally monitor battery voltage and auto-
matically optimize charging, the MC-612
uses up to 12 time and voltage increments
to ensure your batteries receive a full charge quickly and
safely.
The MC-612 lets you choose from a variety of selectable
preset programs to best suit your charging needs. I I t t s s

grams support most popular battery types, including standard and deep-cycle flooded
batteries, AGM, gel, and Optima (spiral wound) technologies. An easy-to-use magnetic reed switch delivers quick, precise regu-
lator adjustment. Should your charging system require individualized adjustment, the MC-612 provides additional user-defined
programming options.
When used with optional alternator and battery temperature sensors, the MC-612 automatically monitors ambient tempera-
tures and compensates for over-temperature conditions by reducing field output.
Alarm outputs connect to audible or visual alarms to warn of dangerous system con-
ditions.
II. SAFETY CONSIDERATIONS
Before installing your MC-612 marine regulator, please take a moment to consider
these guidelines for safe regulator installation. Failure to work safely could result in per-
sonal injury or damage to your electrical system.
1.
Always disconnect your battery banks and ensure that switches are "OFF" prior to
installing your regulator.
2.
Remove loose-fitting clothing or jewelry, which could become entangled in your motor or
other machinery.
3.
Wear ANSI-approved safety glasses.
4.
DO NOT attempt to modify the regulator. Alterations could result in damage to your
charging system, and will void your warranty.
5.
Do not attempt installation if tired or fatigued.
6.
Ensure the engine has cooled before initiating installation.
7.
Do not attempt installation while using alcohol or any medication that could impair your
judgment or reaction time.
8.
Always use the right tool for the job. Improper tool use may damage the regulator or
your boat, and could result in personal injury.
9.
Take time to read the manual. Equipment damage and possible injuries may result from
an incomplete understanding of the installation and operation of the MC-612 regulator.
If you are unfamiliar with marine electrical systems, consult with a licensed marine
electrician.
III. BASIC INSTALLATION
The MC-612 can be purchased with or without a standard 54" harness. When
installing without the harness, or if the wiring needs to be extended beyond the length
of the harness, marine grade 12AWG (American Wire Gauge) wire should be used.
