INSTALLING THE AT10.1
12
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.
