SERVICING THE AT10.1
60
Rotate the rectifier assembly into position in the enclosure. Line up the
metal tab with the mounting hole on the back panel of the AT10.1 and
slide the assembly into position. Replace the shroud as described in the
previous section. Tighten all screws and restart the AT10.1.
Replacing the optional dc filter assembly (A7)
The dc filter assembly consists of a diode heat sink, inductor L2, and one
or two capacitors installed on a single bracket.
Turn off and remove all power to the AT10.1. Remove the plexiglas
safety shield. Disconnect the battery from the output terminals TB1(+/-).
Find the flying lead from the inductor L2 (wire # 50) and disconnect the
other end from the center terminal of inductor L1 (at the upper right
corner of the rear panel). Disconnect wire # 15 from the quick-connect
terminal at the top center of the diode heat sink, and remove wire # 54
from terminal E7 on the front circuit board on the rectifier assembly.
Carefully note which terminal the wire is connected to. Remove the four
screws at the top of the dc filter bracket. The bracket and the inductor will
both fall forward, away from the rear panel.
Lift the filter bracket up about .25in / 6.4mm to release it from the clips at
the bottom of the bracket. Swing the filter assembly outward to the left,
rotating it so that the heat sink comes out first and the capacitor(s) last.
Install the replacement filter assembly by inserting the capacitor end first,
and rotating the assembly inward so that the heat sink is last to go in.
Push the bottom edge of the bracket into the clips in the rear panel, and
install the four screws at the top of the bracket.
Connect wire # 15 to the quick-connect terminal at the top center of the
diode heat sink. Route the flying lead from the inductor L2 (wire # 50)
and connect it to the center terminal ("2") of the inductor L1. Reconnect
wire # 54 to terminal E7 of the front circuit board on the rectifier
assembly. Replace the shroud and the safety shield.
Replacing the ac input or dc output circuit breaker (CB1, CB2)
Turn off and remove all power to the AT10.1. Remove the plexiglas
safety shield. Disconnect the battery from the output terminals TB1(+/-).
Check with a voltmeter before proceeding. This includes remote sense
wires if they were installed. Remove the two circuit breaker mounting
screws on the front panel, and carefully rotate the circuit breaker upward
and pull it out of the enclosure. Remove the wires from the terminals, one
at a time, and transfer the wires to the terminals of the replacement
breaker. Be sure the terminal screws are tight. Install the replacement
breaker into the front panel, rotating it downward into place. Install the
two mounting screws.
