NOTES:
1. Locate the Truecharge2 Series Battery Charger unit away from
batteries in a well ventilated compartment.
2. Always have someone within range of your voice or close enough to
come to your aid when you work near a lead-acid battery.
3. Always have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.
4. If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enters your eye, immediately flood it with running
cold water for at least twenty minutes and get medical attention
immediately.
5. Use extra caution to reduce the risk or dropping a metal tool on the
battery. It could spark or short circuit the battery or other electrical
parts and could cause an explosion.
6. Batteries can produce a short circuit current high enough to weld a ring
or metal bracelet or the like to the battery terminal, causing a severe
burn.
7. When removing a battery, always remove the negative terminal from
the battery first for systems with grounded negative. If it is grounded
positive, remove the positive terminal first. Make sure all loads
connected to the battery and all accessories are off so you don’t cause
an arc.
BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE AND EXPLO-
SION FROM VENTED GASES HAZARDS
• Always wear proper, non-absorbent gloves, complete eye protection,
and clothing protection. Avoid touching your eyes and wiping your
forehead while working near batteries. See note #4.
• Remove all personal metal items, like rings, bracelets, and watches
when working with batteries. See notes #5 and #6.

such as removing or not removing cell caps while charging, whether
equalization is acceptable for your battery, and recommended rates of
charge.
2. For flooded non-sealed batteries, add distilled water in each cell until
battery acid reaches the level specified by the battery manufacturer.
This helps to purge excessive gas from cells. Do not overfill. For a
battery without removable cell caps, carefully follow manufacturer's
instructions.
Precautions When Placing the Battery Charger
NOTE: For North American marine installations, external connections to the
charger shall comply with the United States Coast Guard Electrical
Regulations (33CFR183, Sub Part I).
EXPOSURE TO CHEMICALS AND GASES HAZARD

total output charge current as a percentage of the maximum
rated charge current. For example, unit model TC4012 has a
maximum rated charge current of 40 A so at 60% the
charger’s current output is 24 A. The numbers below the
LEDs represent the percentage values. See “Reading
Onboard Display LEDs” on page 41.
NOTE: When the maximum Charge Output current is
limited via the optional remote panel, the LEDs will still
display the total charge output current as a percentage of the
maximum rated charge current and NOT as a percentage of
the limited charge current.

8 Truecharge2 Series Battery Charger Owner’s Guide
Preparing For Installation
NOTE: The Truecharge2 Battery Charger is designed to be permanently
mounted. Figure 4 shows a typical installation with three batteries, a battery
temperature sensor (BTS) and a remote panel (both optional). It also shows
the AC and DC wiring and protection devices required for a typical
installation. Means of over-current protection and disconnection must be
incorporated into the fixed wiring, in accordance with the electrical code
that governs each installation.
IMPROPER INSTALLATION BY AN UNQUALIFIED INSTALLER
The battery charger must be installed by a qualified installer in
accordance with all applicable local or national installation codes.
Examples of such codes are the US National Electrical Code (NFPA 70),
the American Boat & Yacht Council standards E-11 and A-31, and the
US Coast Guard Electrical Regulations (33CFR183).
Failure to follow these instructions can damage the unit and/or
