I. INTRODUCTION
The microprocessor-controlled Max Charge
MC-624 is the most advanced regulator avail-
able. Designed to continually monitor battery
voltage and automatically optimize charging, the
MC-624 uses up to 12 time and voltage increments to
ensure your batteries receive a full charge quickly and safe-
ly.
The MC-624 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-624 to your alternator right out of the box.
Six additional preset programs sup-
port 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 regulator adjustment. Should your charging system
require individualized adjustment, the MC-624 provides additional user-defined programming options.
When used with optional alternator and battery temperature sensors, the MC-624 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 conditions.
II. SAFETY CONSIDERATIONS
Before installing your MC-624 marine regulator, please take a moment to consider
these guidelines for safe regulator installation. Failure to work safely could result in
personal 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 regu-
lator 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-624 regulator. If you are unfamiliar with marine electrical systems, consult
with a licensed marine electrician.

III. BASIC INSTALLATION
The MC-624 is shipped with either a Port or Starboard harness. If the wiring needs
to be extended beyond the length of the harness, marine grade 12AWG
(American Wire Gauge) wire should be used.
