Balmar 96 Series Installation And Operation Manual

96-SERIES ALTERNATOR
MAX CHARGE MC-620
MULTI-STAGE
VOLTAGE REGULATOR
INTRODUCTION
This manual covers the installation, configuration and use of the
Balmar Max Charge MC-620 regulator and 96-Series alternators.
These two products are designed to be used together to provide up
to 4.8kW of smart, multi-stage charging for 48-volt batteries.
The MC-620 Balmar Max Charge regulator provides precise voltage
control for Balmar's 96-Series high-output 48-volt alternators. The
MC-620 features user selectable programs for all major battery
types. In addition to the user selectable preset programs, the MC-
620 features a wealth of advanced programming modes which
make it possible to tailor charging to a wide variety of environments.
When used in conjunction with the (required, not included) MC-
TS-A alternator and (optional) MC-TS-B battery temperature
sensors, the MC-620 features the ability to monitor and respond to
a range of ambient temperature conditions, including reduction or
discontinuation of charging voltages, should an over-temperature
condition occur at the alternator or the batteries.
The 96-Series alternators charge 48V battery banks with
unprecedented power in a mid-sized J-180 mount case. Both the
60A and 100A versions feature impressively low turn-on speeds
and excellent performance at low rpms.

Safety Considerations
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 prior to
installing regulator and alternator.
3. Wear ANSI-approved safety eye-wear
and protective gear.
4. DO NOT attempt to modify the regulator
or alternator. Modifications could result
in damage to your charging system, and
will void your warranty.
5. DO NOT attempt installation if you are
tired or fatigued.
6. Ensure that the engine has cooled before
initiating installation.
7. DO NOT attempt regulator 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
12
or your vessel, and could result in
11
personal injury.
12
9. Take time to read the manual. Equipment
13
damage and possible injuries may result
15
from an incomplete understanding of the
15
installation and operation of the MC-620
15
regulator and 96-Series alternators. If
16
you are unfamiliar with marine electrical
17
systems, consult with a licensed marine
18
electrician.
