1.6. CHANGING TRANSFORMER TAPS
Before you wire ac power to the AT10.1, check the wiring of the main
transformer (T1), to be sure it is connected for your ac input voltage. The
AT10.1 accepts standard input voltages of 120, 208 or 240 Vac by
changing jumpers on T1. No other changes are required. The AT10.1 is
wired at the factory for 240 Vac, except on special order. Models for 220,
380 or 416 Vac at 50/60 Hz are available on special order.
EXCEPTION: An AT10.1 battery charger rated for 480 Vac input uses a
special transformer that has no taps or jumpers. The 480 Vac
transformer cannot be used for any other input voltage.
Before changing the T1 taps, be sure that ac and dc supplies to the AT10.1
are turned off and locked out. Verify that no voltage is present by using a
voltmeter at terminals TB1-L1 and TB1-L2 (ac), TB1(+) and TB1(-) (dc)
and remote sense terminals (dc). Note that turning off the ac and dc circuit
breakers on the AT10.1 does not eliminate live voltages inside the
enclosure. Also de-energize any external wiring to the alarm relay
contacts.
Verify that all voltages within the enclosure are de-energized and locked
out. See Section 3.5 for necessary steps to follow when accessing internal
components within the AT10.1. Change the jumpers on T1 as shown in
the table on the next page. All transformers have (2) jumpers; always use
both as specified in the table. The transformers used in the small enclosure
(586) use piggyback quick-connect terminals. The transformers in the
larger enclosure (594) use 10-32 stud terminals.
Models designed for 220 Vac, 50/60 Hz have no jumpers, and can be used
only for that voltage. Models designed for 380 or 416 Vac also have no
jumpers, and can be operated on either voltage.
NOTE: This procedure refers only to Group I AT10.1 battery chargers
(rated 6-25 Adc). A different procedure exists for Group II AT10.1
battery chargers (rated 30-100 Adc). Please refer to the Operating and
Service Instructions specific to the Group II AT10.1 battery charger for
changing the transformer taps on these larger units. Otherwise, damage
to your charger and equipment may occur.

1.7. MAKING THE AC INPUT CONNECTIONS
Follow these steps to connect ac power to the AT10.1:
1. Be sure the AT10.1 main transformer (T1) is properly connected for your ac
input voltage. See Section 1.6 for details.
2. Use a branch circuit breaker or fused disconnect switch, properly sized for
the maximum input current of the AT10.1, as shown in the table below. This
device should have lockout capability so that the ac input can be de-
energized and locked out for maintenance. A time delay circuit breaker or
slow-blow fuse is recommended.
3. Size the ac input wiring per the National Electric Code (NEC) and local
codes for the rating of the branch circuit breaker or fused disconnect switch.
4. Do not run external ac and dc power wiring, feeding the battery charger,
through the same conduit.
5. All specific requirements of your facility take precedence over these
instructions.
PROCEDURE
1. Remove the safety cover.
2. Run the ac wiring to terminals TB1-L1, TB1-L2 and TB1-GND on the I/O
panel in the enclosure. Compression lugs accepting wire sizes #14-6 AWG
wire are supplied for your convenience. To make these connections, strip the
insulation .50in / 13mm on the incoming wires and connect the wires to the
appropriate lugs as shown on the next page.
3. Using a flat-head screwdriver, securely tighten the compression screws on
the lugs to 35-45 in-lb / 4.0-5.1 Nm.
4. Reinstall the safety cover after you have made and checked all connections.

Follow these steps to connect the battery to the AT10.1:
1. Size the dc wiring to minimize voltage drop. The acceptable wire size
depends on your installation. As a guideline, the voltage drop should not
exceed 1% of nominal output voltage at full current. Refer to the table below
to determine the voltage drops for various wire sizes, currents and distances.

WIRE SIZE
(AWG) 612 16 20 25
#16 2.5V 5.0V 6.7V 8.2V 10.5V
#14 1.6V 3.2V 4.2V 5.3V 6.6V
#12 1.0V 2.0V 2.6V 3.3V 4.2V
#10 0.63V 1.3V 1.7V 2.1V 2.6V
#8 0.40V 0.80V 1.1V 1.3V 1.7V
#6 0.25V 0.50V 0.66V 0.83V 1.1V
#4 0.16V 0.32V 0.42V 0.52V 0.65V
EXAMPLE: 100ft / 30.5m of #8 AWG wire at 16A has a 1.1V drop.
2. The AT10.1 is factory wired to regulate output voltage at the output
terminals. If the total voltage drop is greater than 1% (e.g., 1.3V for a 130
Vdc system), remote sense wiring is recommended, see Section 1.9.
3. Do not run external ac and dc power wiring, feeding the battery charger,
through the same conduit.
4. All specific requirements of your facility take precedence over these
instructions.
PROCEDURE
1. Use a dc disconnect switch or circuit breaker between the AT10.1 and dc
bus. This device should have lockout capability to allow the AT10.1 to be
disconnected from the dc bus for maintenance.
2. Remove the safety cover.
3. Run the dc wiring to terminals TB1(+) and TB1(-) on the I/O panel in the
enclosure. Compression lugs, accepting wire sizes #14-6 AWG, are supplied
for your convenience. To make these connections, strip the insulation .50in /
12.7mm on the incoming wires. Connect the wires to the appropriate lugs as
shown on the next page.
4. Using a flat-head screwdriver, securely tighten the compression screws on
the lugs to 35-45 in-lb / 4.0-5.1 Nm.
5. Reinstall the safety cover after you have made and checked all connections.

1.9. WIRING THE AT10.1 FOR REMOTE SENSING
You can wire the AT10.1 to regulate the output voltage at the battery
terminals, instead of at the charger output terminals. Remote sensing does
the following:
1. Compensates for voltage drop in the dc wiring between the AT10.1 and the
battery.
2. Directly monitors the battery or dc bus voltage. The front panel meter
displays the actual voltage on the battery or dc bus.
You wire the AT10.1 for remote sensing by installing twisted pair cabling
from the AT10.1 remote sense terminals to the battery terminals. The
AT10.1 control circuitry then measures the dc voltage at the battery
terminals, and controls the output of the charger to maintain the battery
voltage at the desired float or equalize voltage.
NOTE: If the remote sense wiring fails, the AT10.1 detects the fault,
and displays E 06 on the front panel meter. See Section 3.2 for details.
CAUTION: The AT10.1 cannot protect against short circuits in the
remote sense wiring. You should install a 1.0A fuse at the battery or dc
bus end of the remote sense cable.
SCHEMATIC
PROCEDURE
1. De-energize and lock out all ac and dc voltages within the AT10.1 enclosure.
Check with a voltmeter.
2. Remove safety shield.
3. Remove the two (2) dc output CU-AL compression lugs.
4. Move lugged end of R14 (with wire # 20) from TB1(-) to REM SENSE(-).
5. Move wire # 21 from TB1(+) to REM SENSE (+).
