2 Installation
2.1 Mounting the TPSD2
When mounting the TPSD2 in any onfiguration, onsider the size and weight of the harger. The wall, ra k,
and/or floor must be able to support the weight of the harger as well as an additional safety fa tor. Verify the
method of mounting and the weight of the TPSD2, using Tables 1, 2, and 3. The lo ation hosen for the harger
should be within an ambient temperature range of 32 to 122˚F (0 to 50˚C) with a non- ondensing relative
humidity no higher than 95%. The TPSD2 should be mounted in an area free of explosive materials and away
from drips and splatter. The TPSD2 utilizes onve tion ooling, so a learan e of at least 6in (152mm) of free air
must be maintained on the top, bottom, and both sides for ooling air. Maintain 36in (914mm) or more of
learan e at the front of the harger in order to allow for operation and maintenan e. The bolts or s rews used
to se ure the harger should be suffi ient length to assure a vibration-free mounting. The preferred fastener is a
ma hine bolt ba ked with a flat washer, lo k washer, and nut. All hardware should be orrosion-resistant.

DC Connection Procedure
To prevent the DC ir uit breaker from tripping when onne ting the battery, onne tions should be done in the
following order.
1. Make sure that the in oming voltage to the harger is turned off.
2. Turn off/open the harger’s AC and DC ir uit breakers.
3. Conne t the battery ables to the harger’s DC output terminals. OBSERVE PROPER POLARITY.
4. Energize the harger by supplying AC voltage and turning on/ losing the harger’s AC breaker. This will harge
the apa itors inside the harger.
5. After 30 se onds, turn on/ lose the DC breaker.

2.4 Alarm Connections
Eight alarm relays (and 10 alarm LEDs) are in luded as a standard feature of the TPSD2. The in luded alarms are
Low DC Current, Low DC Voltage, High DC Voltage, High Voltage Shutdown, AC Failure, Negative Ground
Dete tion, Positive Ground Dete tion, and Summary alarm. Ea h alarm in ludes two sets of form ‘C’ onta ts,
enabling the user to onne t multiple remote annun iators. Refer to Figure 8 for alarm onta t onne tions.
Alarm LEDs are provided for the following alarms: AC Fail, Low DC Voltage, End of Dis harge, High DC Voltage,
High Voltage Shutdown, Low DC Current, Overload/Current Limit, Positive Ground, Negative Ground, and
Summary. Refer to Figure 9 below.
If an alarm ondition o urs for a default time of longer than 5 se onds, the Summary alarm relay will a tivate if
the orresponding alarm is in luded in the Summary alarm. The HVSD alarm is default set to trigger after 20
se onds. When an alarm a tivates, the spe ifi indi ator on the front panel will light, any onne ted remote
annun iators will a tivate, and the display will y le through all a tive alarms.
All alarm onta ts for the S2A-198 relay board are designed to be fail-safe. In other words, if both the AC and DC
power are removed, ea h alarm will be indi ating the harger’s urrent state. To a omplish this, ertain alarm
relays are de-energized on failure (su h as Low DC Current), and ertain alarm relays are energized on failure
(su h as High DC Voltage). Refer to Table 7 for the logi of ea h alarm and refer to Table 8 for alarm onta t
spe ifi ations.

2.4.1 Alarm Connection Procedure
Before making any onne tions to the TPSD2, ensure that the AC power is off at the main breaker box and the
harger’s breakers are off. Verify that no voltage is present by using a voltmeter at all input and output terminals.
For relays mentioned as ENERGIZED on alarm ondition:
If it is desired that the annun iator be a tive until the alarm triggers, onne t the annun iator leads to the
NC and C onta ts of the desired alarm (lo ated on the relay alarm onta ts on S2A-198 board). If it is
desired that the annun iator be dea tivated until the alarm triggers, onne t the annun iator leads to the NO
and C onta ts of the desired alarm.
For relays mentioned as DE-ENERGIZED on alarm ondition:
If it is desired that the annun iator be a tive until the alarm triggers, onne t the annun iator leads to the
NO and C onta ts of the desired alarm (lo ated on the relay alarm onta ts on S2A-198 board). If it is
desired that the annun iator be dea tivated until the alarm triggers, onne t the annun iator leads to the NC
and C onta ts of the desired alarm.
EXAMPLE A ustomer wants a green lamp to be illuminated
at all times and wants a red lamp to illuminate and a speaker
to sound when the Summary alarm triggers. The ustomer
would make the onne tions to the NC and C onta ts on one
set of the Summary relay onta ts between the speaker and a
power supply. On the other set of Summary relay onta ts,
the ustomer would onne t the NO and C onta ts between
the green lamp and power supply, and would onne t the NC
and C onta ts between the red lamp and power supply. Refer
to Figure 10.

2.4.2 Understanding the Alarms
HIGH DCV SHUTDOWN ALARM will trigger and the red “HIGH VOLTAGE SHUT DOWN” LED will turn on if the
output DC voltage of the harger rises above the alarm threshold for longer than 20 se onds and there is load on
the harger. This an be aused by maladjustments of the output voltage settings, or in rare ases, by a failure
of an internal harger omponent. If the High DC Voltage Shut Down alarm a tivates, the DC output of the harger
is shut off by tripping the AC breaker to prevent irreversible damage to the battery. To reset, press the ALARM
RESET button on the front panel, then lose the AC breaker.
NOTE The High Voltage Shutdown alarm will not trigger if there is a Low Current alarm present.
HIGH DCV ALARM will trigger and the red “HIGH DC VOLTAGE” LED will turn on if the output DC voltage rises
above the spe ified voltage threshold of the alarm for longer than 5 se onds. This an be aused by
maladjustments of the output voltage settings, or in rare ases, by a failure of an internal harger omponent.
LOW DCV ALARM will trigger and the red “LOW DC VOLTAGE” LED will turn on if the DC voltage falls below the
spe ified voltage threshold of the alarm for longer than 5 se onds. This an be due to an AC Failure or the harger
is overloaded into deep- urrent limit. It ould also be aused by maladjustments of the output voltage settings,
or in rare ases, by a failure of an internal harger omponent.
NEGATIVE GROUND ALARM will trigger and the red “NEGATIVE GROUND FAULT” LED will turn on if 1.2mA or
greater urrent is measured between the negative terminal of the battery and earth ground. The alarm will lear
on e the negative ground ondition is no longer present. If the harger has Ground Dete tion disabled, this alarm
will not fun tion.
POSITIVE GROUND ALARM will trigger and the red “POSITIVE GROUND FAULT” LED will turn on if 1.2mA or
greater urrent is measured between the positive terminal of the battery and earth ground. The alarm will lear
on e the positive ground ondition is no longer present. If the harger has Ground Dete tion disabled, this alarm
will not fun tion.
AC POWER FAIL ALARM will trigger, the green “AC ON” LED will turn off, and the red “AC FAILURE” LED will
turn on when the AC power to the harger is lost. The alarm will automati ally reset when AC power is restored
to the harger. When AC power is lost, the front panel display and indi ators will remain powered by the onne ted
batteries.
SUMMARY ALARM is triggered and the “SUMMARY” LED will turn on when any of the following alarms are
a tivated:
 Low DC Voltage  Positive Ground*  AC Failure*
 High DC Voltage  Negative Ground*  S2A-407S Failure**
 Low DC Current*
* Optional to in lude in Summary Alarm
** If appli able
LOW DC CURRENT ALARM will trigger and the amber “LOW DC CURRENT” LED will turn on if the output DC
urrent of the harger falls below the alarm threshold for longer than 5 se onds. This an be aused by the load
(if appli able) being dis onne ted or if the battery (if appli able) has rea hed a full harge. This ould also be the
result of maladjustments of the output voltage settings. In rare ases, this ould be the result of ertain parallel
setups in whi h the other harger is set up to arry all the load. This alarm an be disabled if onsidered a nuisan e
alarm.
Most alarms have adjustable time delays to energize; ranging from 0 through 255 se onds. Refer to Table 9 for
the fa tory setting of ea h alarm.
NOTE All alarms automati ally reset when the alarm ondition is orre ted, ex ept the High Voltage Shutdown
alarm. Refer to the orresponding alarm des ription above for reset instru tions.

2.5 External Temperature Compensation (Option 11W/11Y)
The natural voltage of a battery hanges as a fun tion of temperature hange. As the battery temperature rises,
the effe tive voltage of the battery de reases. Without Temperature Compensation, the battery harger will
always produ e a set onstant output voltage. As the battery temperature in reases, this onstant voltage will
then indu e a higher output urrent from the harger. This higher urrent an result in over harging the battery,
whi h in turn an result in damage to the batteries.
Temperature Compensation ombats this over harging by adjusting the harger’s output voltage based on the
temperature read by the temperature probe. An internal temperature probe is standard and will ompensate for
overall ambient temperature hanges if the batteries and harger are in the same room. The a ura y of
temperature ompensated harging an be greatly enhan ed by using an optional remote temperature probe
dire tly on the battery (Option 11W/11Y).
Option 11W in ludes a 24-foot long temperature probe and Option 11Y in ludes a 100-foot long temperature
probe. With either option, approximately two feet of the probe is taken inside the harger en losure.
External Probe Connection Procedure
Before making any onne tions to the TPSD2, ensure that the AC Power is off at the main breaker box and the
harger’s breakers are off. Verify that no voltage is present by using a voltmeter at all input and output terminals.
Procedure for Standard Chargers
1. Lo ate the TS-6 terminal strip inside the harger.
2. Conne t wire marked F to terminal 1 and wire marked G
to terminal 2. Refer to Figure 11.
3. Conne t the bla k lead of the external probe to the other
end of terminal 1, and the red lead to the other end of
terminal 2.
4. Pla e the external probe in a desired lo ation.
(It is re ommended that the battery manufa turer be
onsulted for pla ement of the probe)
Procedure for Chargers with S2A-406 Board
1. Lo ate the J4 terminal strip on the S2A-406 board.
2. Toggle the SW1 swit h on the S2A-406 board to the
External position. Refer to Figure 12.
3. Conne t the bla k lead of the external probe to
terminal 2 of J4, and the red lead to terminal 1 of J4.
4. Pla e the external probe in a desired lo ation.

2.6 Load Sharing
All TPSD2 hargers in lude the Load Sharing feature. Load sharing allows the user to parallel with any identi al
TPSD2 to share a DC load and therefore redu e the strain on ea h harger. When onne ted, identi al TPSD2
hargers are for ed to share the load within ±5% for individual unit outputs greater than 10% of the rated output.
Chargers to be paralleled MUST be the same output (voltage and urrent).
NOTE Ground Dete tion should only be enabled on one harger when load sharing. See Se tion 2.9 to disable.
If load sharing is to be used with a battery that requires periodi Equalize y les, the hargers should also operate
in Remote Equalize mode (See Se tion 2.7 for instru tions).
Load Sharing Procedure
Before making any onne tions to the TPSD2, ensure that the AC power is off at the main breaker box and that
all of the hargers’ breakers are off. Verify no voltage is present by using a voltmeter at all input and output
terminals.
Procedure for Standard Chargers
1. Conne t the DC output of all hargers in parallel to the same DC load/battery.
2. Lo ate terminal strip TS-5 inside the hargers.
3. Conne t the LS terminal of one harger to the LS terminal of the next harger. This onne tion an be made
with a 16 AWG wire. Refer to Figure 13.
4. On e batteries are fully harged and/or loads are stabilized, turn OFF all hargers ex ept for one.
5. Take a voltage reading of the Float voltage on the output of the harger.
6. Turn on the next harger, turn off the first harger.
7. Set the output voltage of the next harger to mat h the first by adjusting the Float voltage using the Settings
Menu (refer to Se tion 3.4.1.1).
8. After all hargers have been adjusted, turn ON all hargers.
9. Repeat steps 4 through 8 for Equalize.
Procedure for Chargers with S2A-406 Board
1. Conne t the DC output of all hargers in parallel to the same DC
load/battery.
2. Lo ate terminal strip J4 on S2A-406 board inside the hargers.
3. Conne t terminal 6 of J4 of one harger to terminal 6 of J4 of the next
harger. This onne tion an be made with a 16 AWG wire. Refer to
Figure 14.
4. On e batteries are fully harged and/or loads are stabilized, turn OFF all
hargers ex ept for one.
5. Take a voltage reading of the Float voltage on the output of the harger.
6. Turn on the next harger, turn off the first harger.
7. Set the output voltage of the next harger to mat h the first by adjusting
the Float voltage using the Settings Menu (refer to Se tion 3.4.1.1).
8. After all hargers have been adjusted, turn ON all hargers.
9. Repeat steps 4 through 8 for Equalize.
Figure 13 – TS-5 Terminal Connections (Schematic Wiring)

2.7 Remote Equalize
A terminal is provided on harger for a Remote Equalize fun tion. For standard hargers, the Remote Equalize
terminal is labeled “RE” and is lo ated on the TS-5 terminal as shown on Figure 13. For hargers with the S2A-
406 board, the Remote Equalize terminal is on terminal 5 of J4 as shown on Figure 14. Conne tions an be made
by using a 16 AWG wire. The harger may be remotely for ed into Equalize by onne ting the Remote Equalize
terminal to negative.
When hargers are onne ted for Load Sharing, they must also be set up to swit h into Equalize at the same
time. This an be a omplished by using the Remote Equalize fun tion of the harger. In addition to wiring the
Load Share wire, the hargers’ Remote Equalize terminals must be onne ted together for Remote Equalize.
In a system, all harger Remote Equalize terminals are onne ted together and when any one master harger is
put into Equalize, all hargers will go into Equalize and the display will read “in Remote Equalize.” To return to
Float Mode, the master harger must be returned to the Float Mode.
CAUTION Damage to the unit will result if the Remote Equalize terminals are shorted to any other AC or DC
voltage sour e or ground on positive grounded hargers.
NOTE Remote Equalize an only be used with other TPSD2 hargers of the same output voltage and urrent.
2.8 Remote Voltage Sensing
Provisions for remote DC voltage sensing are provided. The sensing ir uit is a tivated when wires from the
battery or load are brought ba k to the Remote Sensing terminals of the harger. For standard hargers, the
Remote Sensing terminals are labeled “RS+” and “RS-” and are lo ated on the TS-5 terminal as shown on Figure
13. For hargers with the S2A-406 board, the Remote Sensing terminals are on terminals 1 & 2 of J5 as shown
on Figure 14. Conne tions an be made by using a 16 AWG wire.
The positive remote sensing lead should ontain an external 1 Amp fuse for negative ground system. The negative
remote sensing lead should be fused for positive ground system. When remote sensing is wired, the unit output
may have to be readjusted to ompensate for the prote tion diodes on the ir uit board.
CAUTION The polarity of the Remote Sensing terminals is riti al. Che k and verify the polarity arefully.
2.9 Ground Detection
Ground Dete tion is available on TPSD2 hargers. The purpose of Ground Dete tion is to determine if the battery
or loads have be ome grounded. If the battery or loads are set up as floating, it is re ommended that Ground
Dete tion be enabled. When Ground Dete tion is enabled, a positive or negative ground fault indi ator will
energize upon dete tion of the spe ified ground. The Ground Dete tion ir uitry monitors amount of ground
urrent, whether it is positive of negative, and will alarm when the threshold of 1.5mA is rea hed (or ex eeded).
TPSD2 hargers are shipped from the fa tory with Ground Dete tion enabled by default. It is re ommended that
Ground Dete tion be disabled if the battery or loads are either positively or negatively grounded. The harger will
indi ate a ground fault at all times if the system is known to be grounded and the Ground Dete tion is enabled.
For TPSD2 hargers whi h are set up to load share, only one harger should have Ground Dete tion enabled. All
other hargers must have Ground Dete tion disabled (see below for steps). If an external Ground Dete tion
system is used, the TPSD2 Ground Dete tion must be disabled.
NOTE La Mar he Mfg. Co. is primarily a manufa turer of battery hargers and not ground dete tion systems. If
a more pre ise system is required, many systems that are designed spe ifi ally for ground dete tion are
ompatible with La Mar he battery hargers.
