o The following equipment is needed:
- Grounded mat for protecting components subject to damage from electro-
static discharges (ESD).
- Screwdriver with a 6 mm wide tip,
- #1 Phillips screwdriver,
- 4.5 mm socket or nut driver,
o Unfasten the screw-posts of the D-subminiature connector on the back panel at loca-
tion “A”. This activity does not apply if the device is for surface mounting.
o If the device has more communication interfaces at locations “B” and/or “C” on the
rear, the screws located diagonally to the interfaces must be removed. This activity is
not necessary if the device is for surface-mounting.
o Remove the four corner caps on the front cover and loosen the screws that become
accessible.
o Carefully pull off the front cover. The front cover is connected to the CPU board with
a short ribbon-cable.
For a device with a detached operator panel, the front part can be directly removed
after the screws are loosened.
o At one end, disconnect the ribbon-cable between the front cover and the CPU board
(å). To disconnect the cable, push up the top latch of the plug connector and push
down the bottom latch of the plug connector. Carefully set aside the front cover.
For a device with a detached operator panel, this step is different. The 7-pin plug X16
must be removed from the CPU (å) board behind the D-subminiature plug and the flat
ribbon connector, which is connected to the 68-pin connector on the device side.
The locations of the printed circuit boards are shown in Figures 8-6 and 8-7.
o Disconnect the ribbon-cables between the CPU board (å) and the I/O boards (ê).
o Remove the boards and place 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, due to the communication connectors.
o Check the jumpers according to Figures 8-8 to 8-12, and Tables 8-2 to 8-9. Change
or remove the jumpers as necessary.
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.
