9. Working in the vicinity of lead-acid batteries is
dangerous. Batteries generate explosive gase s during
normal operation. Therefore, it is of utmost importance
that you read this manual and follow the instructions
exactly each time you use the charger .

10. To reduce the risk of battery explosion, follow these
instructions and those published by the battery
manufacturer and the manufacturer of any equipment you
intend to use in the vicinity of the battery. Review
cautionary markings on these products and on the engine.

Personal Precautions When Working With
Batteries

1. Have someone within range of your voice or close
enough to come to your aid when you work near a lead ­acid battery.

2. Have plenty of fresh water and soap nearby in case
battery acid contacts skin, clothing, or eyes.

3. Wear proper, non-absorbent gloves, complete eye
protection, and clothing protection. Avoid touching your
eyes and wiping your forehead while working near
batteries.

4. If battery acid contacts skin or clothing, wash
immediately with soap and water. If acid enters yo ur eye,
immediately flood it with running cold water for at least
twenty minutes and get medical attention immediately.

5. Never smoke or allow a spark or flame near the engine or
batteries.

6. 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.

7. Remove all personal metal items, like rings, bracelets,
and watches when working with batteries. 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.

8. If you need to remove 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.

9. Never charge a frozen battery.

PREPARING TO CHARGE

10. Make sure the area around the battery is well ventilated.

11. Make sure the voltage of the batteries matches the output
voltage of the battery charger.

12. Clean battery terminals. Be careful to keep corrosion
from coming into contact with your eyes and skin.

13. Study and follow all of the battery manufacturer's
specific precautions, such as removing or not removing
cell caps while charging, whether equalization is
acceptable for your battery, and recommended rates of
charge.

14. 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.

BATTERY CHARGER LOCATION

15. Locate the Truecharge™ 2 Battery Charger unit away
from batteries in a well ventilated compartment.

16. Never place the Truecharge™ 2 Battery Charger unit
directly above batteries; gases from a battery will corrode
and damage the charger

17. Never allow battery acid to drip on the charger when
reading gravity, or filling battery.

18. Do not operate the charger in a closed in area, or restrict
the ventilation in any way.

19. Do not place a battery on top of the charger.

20. For North American marine installations, external
connections to the charger shall comply with the United
States Coast Guard Electrical Regulations (33CFR183,

Location

Install the Truecharge™ 2 Battery Charger in a location that
meets the following requirements:

Condition Requirement

Dry The Truecharge™ 2 Battery Charger must be installed in a dry

location not subject to moisture especially rain, spray, or
splashing bilge water.

Clean The Truecharge™ 2 Battery Charger should not be exposed to

metal filings or any other form of contamination.

Cool The ambient air temperature should be between 0 °C - 50 °C

(32 °F - 122 °F) for best performance.

Ventilated There must be at least 10 cm (4 in.) of clearance on the top and

bottom ends of the Truecharge™ 2 Batter y Charger for air flow
and at least 6 cm (2.5 in.) of clearance on either side (see Figure
2-3). Ventilation openings on the charger must not be obst ruct e d.
If the charger is mounted in a tight fitting compartment, the
compartment must be ventilated with cut-outs to prevent the
charger overheating.

Safe This battery charger is ignition protected, so it can be installed in

areas containing gasoline tanks or fittings which require ignition
protected equipment. Xantrex recommends, however, that it is
safest not to install electrical equipment in these areas.

Close to
batteries

The Truecharge™ 2 Battery Charger should be installed as close
as possible to the batteries, but not in the same compartment to
prevent corrosion. Avoid excessive cable lengths and use the
recommended wire sizes. Xantrex recommends installing with
cables sized to achieve less than 3% voltage drop on battery
cables under full load. This will maximize the performance of the
charger.

When planning to install the Truechar ge™ 2 Battery Charger,
be sure that you consider the location and orientation
carefully. The Truecharge™ 2 Battery Charger is considered
to have an IP rating of IP-32, if installed in either of two
specific orientations [shown in Figure 2-2 a) and b)]. This
rating means that it meets standards to prevent dripping water
from entering the enclosure, and causing shock hazard and
damage to equipment.

The other possible mounting orientations will not prevent the
entry of dripping water, and are not suitable for marine or
other moist environments without the installation of
additional drip protection. They are only acceptable for use in
locations that are always dry [shown in Figure 2-2 c) and d)].

The environment, therefore, will determine the mounting
orientations that are suitable for each installation. Is the
installation environment one that will always be dry or will
moisture or condensation sometimes enter the area?

WARNING: Shock hazard

In marine environments, there is a likelihood that condensation will
be present, and may drip on to the charger. Use the appropriate
mounting orientations as shown in Figure 2-2.

Over-current protection disconnect

Electrical codes require the DC circuit from each battery to
the charger to be equipped with a disconnect and an over­current protection device, usually within 7 inches (17.8 cm)
of each battery

1

. The devices are usually DC-rated circuit
breakers, fused disconnects, or a separate fuse and disconnect
for each circuit. These devices must be rated for DC voltage
and current and be rated to withstand the short circuit current
available from the connected battery bank. Do not substitute
devices rated only for AC voltage; they may not operate
properly.

The current rating of the DC fuses must be correctly matched
to the size of the DC wiring used, in accordance with the
applicable codes. This helps to protect the installation against
fire in case of any overcurrent or short circuit fault.

a minimum of 75C, and sized based on the AC input current
to the charger (see Appendix A) and on the value of
overcurrent protection provided.
For example, in US NEC, you may use a 14 AWG wire with
a 15 A breaker for up to 12 A continuous current (or 12 A WG
for a 20 A breaker for up to 16 A continuous current) or for
230 Vac application, you may be able to use either a 2.5mm

2

wire with a 16 A breaker or use 1.5 mm

2

wire with a 10 A
breaker. Note that every jurisdiction will have different
requirements as will each application, so research the
regulations for your local jurisdiction to determine which
wire size and type is correct based on the maximum AC input
current marked on the chargers and given in Appendix A.
Wire Types:

• for marine applications, the United States American

Yachting and Boating Council (ABYC) requires stranded
wire, which is more robust than solid wire when exposed
to vibration

• for RV applications, the United States National Electrical

Code (NEC) allows solid wire in multi-conductor cable,
however, stranded wire is also acceptable which will

withstand vibration better.
The AC wiring supplying the Truecharge™ 2 Battery
Charger must be protected by the correct size and type of
branch-circuit rated fuse or breaker to meet the applicable
installation codes. If a fuse is used instead of a breaker, a
correctly rated disconnect switch is required ahead of the fuse
so that power can be turned off, allowing fuse replacement
and safe maintenance of other equipment on the mains
circuit.

Connecting the DC Chassis Ground (Earth)

The Truecharge™ 2 Battery Charger Battery Charger must be
connected to a ground ed, metal, permanent wiring system, or
an equipment-grounding conductor should be run with the
circuit conductors and connected to the equipment-grounding
lead on the charger. Connections to the battery charger must
comply with all local and application-specific codes and
ordinances.

Xantrex recommends that you install a DC chassis ground
(earth) wire from the ground stud on the Truecharge™ 2
Battery Charger to the engine bus or DC ground bus. The DC
chassis ground (earth) wire should be sized correctly with the
power conductors, and both must be sized for the battery
fuses that are used to protect the DC wiring. Refer to your
local electrical codes to verify the requirements in your
jurisdiction for your application.

To connect the DC chassis ground (earth):

1. Locate the ground stud on the Truecharge™ 2 Battery

Charger.

2. Connect the DC chassis ground (earth) from the ground

stud to the ground bus. See Figure 2-1, “Typical

Truecharge™ 2 Battery Charger System Installation” on

page 2–3.

Use a flat washer, a lock washer and a nut (included in

the installation kit) to secure the connection.

3. Tighten the nuts to 2.3 N-m (20 lb-in.) torque and test

that the wire is secure. Do not over-tighten as this may

result in damage to the charger.

Installing DC Wiring

The procedure for installing the DC wiring applies to a single
battery, as well as multiple batteries or battery banks.

1. Plan the route that the DC wires will follow , keeping it as

short as possible. Measure and cut the required wire

length, after allowing some extra length for connections

and to provide slack in the wires for strain relief.

2. Identify the positive wires, by using color-coded wire, or

by marking both ends of the wire with colored tape, or

similar kind of marking. Repeat with a different color for

the negative. Most installation codes recommend

coloring the positive red and the negative black.

3. Install a DC circuit breaker or fused disconnect in each

positive cable that is as close to the battery positive

terminal as possible.

Consult your local electrical codes regarding the distance

allowed between the battery and the fuse or breaker. For

example, for most situations ABYC standard E-11

requires no more than 7 inches (17.8 cm). Be sure the

breaker or fused disconnect is open.

4. Route the wiring to the batteries and to the Truecharge™

2 Battery Charger. Avoid routing wiring through an

electrical distribution panel, battery isolator, or other

device that will add voltage drops.

WARNING: Energy and explosion hazard

To help prevent accidental shorts or sparks, leave the DC
disconnects or breakers in the Off position or DC fuses removed
from their fuse holders until installation is complete.

Important:

You may find it helpful to label each cable,
associating it with the battery bank it is connected to. For
example, bank 1 (–), bank 1 (+), bank 2 (–), and so on.

1. Switch off all devices operating from the battery.

2. Connect the ring terminal on the sensor directly on to the
negative battery stud, or affix the double-sided adhesive
backing to the sensor back and attach the sensor to the
side of the battery to be monitored.

3. Route the sensor cable to the charger and plug it to the
BTS port on the rear panel.

Note: If there are multiple batteries, attach the BTS to the

battery that is located in the warmest ambient temperature.

Important:

To minimize noise interference, the remote and
BTS cables should be routed away from the AC mains line and
DC battery cables.
Also, if the BTS is unplugged after a battery over temperature
fault, the charger will stop charging. Use the onboard display to
set the appropriate temperature setting to restart charging.

Mounting the Optional Remote Panel

To mount the remote panel:

1. Choose a location for the remote panel that is within

15 m (50 ft.) from the charger. Use only the
six-conductor communications cable (RJ-12) that came
with the remote panel.

2. Use the mounting template provided with the Remote

Panel to predrill mounting holes.
Take care that there is nothing behind the surface for you
to damage such as other cables or pipes.

3. Connect the RJ-12 connector to the remote panel and

route it to the charger. Be careful not to damage the
connector locking tab when routing the cable. You can
use some tape to protect the locking tab from catching on
something and breaking off when routing the cable.

4. Once the Truecharge™ 2 Battery Charger is mounted,

plug the other RJ-12 connector into the Remote port on
the rear panel of the Truecharge™ 2 Battery Charger.

Note: The RJ-12 communications cable used for the remote

panel uses six conductors. The sensor cable for the BTS on the
other hand, uses four conductors – an RJ-11 cable.

Configuring the Truecharge™ 2 Battery
Charger

Once the charger is connected to a battery on bank 1 or to
AC, it is live and it may be configured. The indicator LEDs
on the onboard display will illuminate for a second (power on
test) before reporting charging and battery status information.

When the remote panel is connected, there will be a short
delay of about 15 seconds before reporting charging and
battery status information. The remote panel will use this
time to query the charger for the current operating conditions.

Configuring the Maximum Output Current
Percentage

Advantages of Current Limiting Feature:

• Gives the user flexibility to custom charge according
to the battery manufacturer’s instructions.

• Allows batteries with a lower current rating to be
charged safely without the need of a new charger.

• Allows drawing less current from an AC source such
as a generator which can prevent an overload of the
generator.

To configure the maximum output current using the
Remote Panel:
NOTE: By default, the Max. Output % is set to 100.

◆ Press the Set Max Output button to select the appropriate
maximum output setting.

The LEDs will indicate which of the five values is being
selected: 100, 80, 60, 40, or 20.

Note: The maximum rated charge current is the only output

current rating affected as a result of pressing the Set Max Output
button. All other output current ratings, such as the absorption
exit current, will not be affected. However, if a setting of 40 or 20
is selected, the equalization charge current will be reduced to a
default of 50% capacity.

Installing Batteries

Replacing old or defective batteries (even installing new
batteries) requires that you disconnect all AC and DC sources
prior to installation.

To replace an old battery:

1. Turn off the AC source by disconnecting the AC line
and/or opening the AC source disconnect.

2. Switch off all devices operating from currently installed
batteries.

3. Disconnect the battery cables from the old battery.
NOTE: For Negative chassis systems, disconnect the
negative cable first, then the positive cable.
For Positive chassis systems, disconnect the positive
cable first, then the negative cable.
Inspect all AC and DC cables for damage and repair, if
necessary.

4. Replace the old battery with the new battery.

5. Reconnect the battery cables to the new battery.
NOTE: For Negative chassis systems, reconnect the
positive cable first, then the negative cable.
For Positive chassis systems, reconnect the negative
cable first, then the positive cable.

WARNING

Battery installation should always be treated like a brand new
installation. This means, that all safety and precautionary
guidelines that were followed prior and during the installation of
the charger, must again be followed in order to avoid risks of
electrical shock, injury, or death.

Important:

If the new battery is different from the old one in
chemistry, temperature, or size, remember to re-configure the
battery settings accordingly.
