1.7. MAKING THE AC INPUT CONNECTIONS
Follow these steps to connect 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 charger 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 stan
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 cover.
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 - 6 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 35-45 in-lb / 4.0-5.1 Nm.
6. Check all connections and reinstall the plexiglas safety cover.
