•
Prepare area of work: Preparing a surface appropriate to electrostatic sensitive devices (EGB). In addition
to this, the following tools are required:
– screwdriver with a 5 mm to 6 mm wide tip,
– a Philips screwdriver size 1,
– 5 mm socket or nut driver.
•
Unfasten the screw-posts of the D-subminiature connectors 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 additional communication interfaces at locations “A”, “C” and/or “B” “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 caps on the front cover and loosen the screws that become accessible.
•
Remove the front panel and tilt it to the side.
Work on the Plug Connectors
CAUTION
Mind electrostatic discharges
Non–observance can result in minor personal injury or material damage.
²
Electrostatic discharges over connections of components, conductor paths or pins are to be avoided by
prior touching of grounded metal parts at any circumstances.
²
Do not plug or withdraw interface connections under power!
The following must be observed:
•
Disconnect the ribbon cable between the front cover and the C-CPU-2 board (No. 1 in Figures Figure 3-2
and Figure 3-3) at the front cover side. 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.
•
Disconnect the ribbon cables between the C-CPU-2 board (1) and the I/O boards ((2) and (3), (depending
on the variant ordered).
•
Remove the boards and set them on the grounded mat to protect them from ESD damage. In the case of
the device variant for panel surface mounting, please be aware of the fact that a certain amount of force
is required in order to remove the C-CPU-2 module due to the existing plug connectors.
•
Check the jumpers according to Figure 3-4 to Figure 3-7 and the following information, and as the case
may be change or remove them.
