Max Charge MC-612
Installation And
Operation Manual
I.
Introduction
The microprocessor-controlled Max Charge MC-612 is the most advanced regulator available. The MC-612 lets
you choose from a variety of selectable preset programs to best suit your charging needs. Its Universal Factory
Program allows you to connect the MC-612 to your alternator right out of the box. Six additional preset pro-
grams support most popular battery types, including standard and deep-cycle flooded batteries, AGM, gel, and
Optima (spiral wound) technologies, as well as special settings for systems supplying halogen lighting. An easy-
to-use magnetic reed switch delivers quick, precise regulator adjustment. Should your charging system require
individualized adjustment, the MC-612 provides additional advanced user-defined programming options.
When used with optional alternator and battery temperature sensors, the MC-612 automatically monitors ambi-
ent alternator and battery temperatures and compensates by adjusting field output to match conditions. Alarm
outputs connect to audible or visual alarms to provide warnings of dangerous system conditions.
II. Safety Considerations
Before installing your MC-612 marine regulator, please take a moment to consider these guidelines for safe reg-
ulator installation. Failure to work safely could result in 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 medication that could impair your judgment or reaction time.
8.
Always use the right tool for the job. Improper tool use may damage regulator or your boat, and could result in per-
sonal injury.
9.
Take time to read the manual. Equipment damage and possible injuries may result from an incomplete understand-
ing of the installation and operation of the MC-612 regulator. If you are unfamiliar with marine electrical systems,
consult with a licensed marine electrician.
