7UM62 Manual
C53000-G1176-C149-3
Caution!
Jumper-setting changes that affect nominal values of the device render the ordering
number and the corresponding nominal values on the nameplate sticker invalid. If
such changes are necessary, the changes should be clearly and fully noted on the
device. Self adhesive stickers are available that can be used as replacement
nameplates.
The following equipment is needed:
− Grounded mat for protecting components subject to damage from electrostatic
discharges (ESD).
− Screwdriver with a 6 mm wide tip,
− #1 Philips screwdriver,
− 4.5 mm socket or nut driver.
Unfasten the screw-posts of the D-subminiature connector on the back panel at
location "A" and "C". This activity does not apply if the device is for surface mounting.
If the device has more communication interfaces at locations "B" and/or "D" on the
rear, the screws located diagonally to the interfaces must be removed. This activity
does not apply if the device is for surface mounting.
Remove the four corner caps on the front cover and loosen the screws that become
accessible.
Carefully pull off the front cover. The front cover is connected to the CPU board with
a short ribbon-cable.
Caution!
Electrostatic discharges through the connections of the components, wiring, plugs,
and jumpers must be avoided. Wearing a grounded wrist strap is preferred. Otherwise,
first touch a grounded metal part. Do not insert or remove the port plugs under live
conditions!
At one end, disconnect the ribbon-cable between the front cover and the CPU board
(Œ). To disconnect the cable, push up the top latch of the plug connector and push
down the bottom latch of the plug connector. Carefully pull off the front cover.
Disconnect the ribbon-cables between the C-CPU-2 board (Œ) and the I/O boards (
to , depending on the variant ordered).
Remove the boards and set them on the grounded mat to protect them from ESD
damage. A greater effort is required to withdraw the CPU board, especially in versions
of the device for surface-mounting, because of the communication connectors.
Check the jumpers according to Figures 3-7 to 3-11, and Tables 3-1 to 3-8. Change
or remove the jumpers as necessary.
The locations of the printed circuit boards are shown in Figures 3-5 (for
) and 3-6 (for Full
Housing
).
