breaker (and/or fuses), and the input surge suppressors. In
addition, you must replace (or rewire) the ac input power isolation
transformer (T1) as described below.
Failure to use properly rated components may damage the AT10.1.
If your AT10.1 was supplied with the 480 Vac 60Hz ac input feature, the
transformer will only accept the listed voltage.
NOTICE
Do not attempt to rewire the 480Vac transformer. If a different ac
input voltage for the AT10.1 is desired, please contact your sales
representative for ordering replacement parts (T1, CB1, VR2-VR5).
If your AT10.1 was supplied with one of the following ac input voltage
features, the transformer is re-tappable:
• 120 or 208 or 240Vac 60Hz
• 120 or 220 or 240Vac 50/60Hz
• 380 or 416Vac 50/60Hz
• 550 or 600Vac 50/60Hz
Before you connect ac power to the AT10.1, inspect the primary wiring of
the ac input transformer (T1). Make sure it is "tapped" for the desired ac
input supply voltage.
NOTICE
Before starting work, disconnect and lock out all external ac and
dc power sources to the AT10.1. Merely turning off (opening)
the front panel ac and dc circuit breakers (CB1/CB2) is not
sufficient to eliminate live voltages inside the enclosure. Verify
that no voltages are present inside the AT10.1, using a
voltmeter at the ac terminals TB1-L1 & TB1-L2, the dc terminals
TB1(+) & TB1(-), the dc remote sense terminals, and any
external wiring to alarm relay contacts.

1.7. MAKING THE AC INPUT CONNECTIONS
!WARNING
The AT10.1 is a commercial product, and not intended for use in a
residential environment, or to be powered by low-voltage public mains.
It is the responsibility of the installer of the AT10.1 to provide suitable ac
supply wiring. Wiring must be approved for use in the country in which
the AT10.1 is installed. When selecting wire sizes, consult the data
nameplate decal affixed to the front panel of the AT10.1 for maximum
voltage and current requirements. The AT10.1 must also be grounded in
accordance with the electrical rules of the country where installed.
Follow these steps to supply proper ac power to the AT10.1:
1. Confirm that the AT10.1 main power transformer (T1) is properly jumpered
for your ac input supply voltage. See Section 1.6 for details.
2. Use a branch circuit breaker or fused disconnect switch upstream from the
AT10.1. This device should have lockout capability so that the ac input
supply to the AT10.1 can be de-energized for unit maintenance. A time
delay circuit breaker or slow-blow fuse is recommended.
3. Size the branch circuit breaker or fused disconnect switch for the maximum
ac input current of the AT10.1. This rating is listed on the left-hand side of
the AT10.1 data nameplate. For a comprehensive list of these maximum ac
input values, access standard (DC5016-00).
NOTICE
If your AT10.1 is wired for 480 Vac input, and is equipped with the standard
AIC ac circuit breaker (no ac fuses), you need a feeder breaker or fuse
rated to interrupt the short-circuit current of your ac supply.
4. Size ac input wiring per the National Electric Code (NEC) and local codes
for the trip rating of the branch circuit breaker or fused disconnect switch.
5. Do not run external ac input power wiring through the same conduit of the
AT10.1 enclosure as external dc output power wiring.
6. All site requirements of your facility take precedence over these instructions.
PROCEDURE
1. Remove the Plexiglas safety shield.
2. Run the ac input supply wiring into the AT10.1, ending at terminals TB1-L1,
TB1-L2, and TB1-GND on the I/O panel board.
3. The AT10.1 features three (3) CU-AL compression lugs on the ac input
terminals, which accept #14 - 1/0 AWG wire. Strip 0.50in / 13mm from the
insulation of the incoming ac input supply wiring.
4. Connect the wires to the appropriate ac lugs as shown on the next page.
5. Using a flat-head screwdriver, securely tighten the compression screws on
the ac lugs to 35-50 in-lb / 4.0-5.7 Nm.
6. Check all connections and reinstall the Plexiglas safety shield.

1.8. MAKING THE DC OUTPUT CONNECTIONS
It is the responsibility of the installer of the AT10.1 to provide suitable dc
output, battery, and dc load wiring. 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.

EXAMPLE: 100ft / 30.5m of #8 AWG wire at 50A has a 3.1 Volt drop.
2. The AT10.1 is factory wired to regulate the 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 AT10.1, 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 Plexiglas safety shield.
3. Run the dc wiring to terminals TB1(+) and TB1(-) on the I/O panel board in
the enclosure. Compression lugs, accepting wire sizes #14-1/0 AWG, are
supplied for your convenience.
4. Strip the insulation 0.5in / 12.7mm on the incoming wires. Connect the
wires to the appropriate dc lugs as shown on the next page.
5. Using a flat-head screwdriver, securely tighten the compression screws on
the lugs to 35-50 in-lb / 4.0-5.7 Nm.
6. Reinstall the safety cover after you have made and checked all connections.
