SERVICING THE AT10.1
60
Replacing the ac surge suppressors (VR2, VR4 or VR5)
Shut down and lock out all power to the AT10.1. Open the door and
remove the safety shield. Disconnect the battery from the output
terminals.
For
VR2
, remove the hardware from the input terminal L1, and remove
the lead of the ac surge suppressor. Install one lead of the replacement
surge suppressor onto the L1 terminal. Replace the other wires and the
hardware. Repeat procedure for the L2 terminal. Tighten all hardware.
For
VR4
, remove the hardware from the input terminal L1, and remove
the lead of the ac surge suppressor. Install one lead of the replacement
surge suppressor onto the L1 terminal. Replace the other wires and the
hardware. Repeat procedure for the
left
ground stud. Tighten all
hardware.
For
VR5
, repeat procedure for the ac surge suppressor connected to the L2
terminal and the
right
ground terminal. Tighten all hardware.
NOTICE
The ac surge suppressors are not polarized.
Replacing the dc surge suppressor (VR1)
Shut down and lock out all power to the AT10.1. Open the door and
remove the safety shield. Disconnect the battery from the output
terminals.
Remove the hardware from the output terminal TB1(+), and remove the
lead of the dc surge suppressor. Install one lead of the replacement surge
suppressor. Replace the other wires and the hardware. Repeat for the
output terminal TB1(-). Tighten all hardware.
NOTICE
The dc surge suppressor is not polarized.
Replacing the dc EMI filter networks (VR6/C4, VR7/C5)
Replace these networks as assemblies. Do not replace individual parts.
Shut down and lock out all power to the AT10.1. Open the door and
remove the safety shield. Disconnect the battery from the output
terminals.
To replace the network VR6/C4, remove the hardware from the output
terminal TB1(-), and remove the lead of the network. Cut the plastic wire
ties holding the assembly tight against the I/O panel. Install one lead of
the replacement network. Replace the other wires and the hardware.
Repeat for the other lead of the network on the ground terminal. For the
network VR7/C5, use the above procedure, but start with the lead on
TB1(+). Tighten all hardware. Replace cut wire ties if possible.
NOTICE
The dc EMI filter networks are not polarized.
