Handling PC boards
KION workstations delivered before
July 1998 are not equipped with the
protective plate covering the PC
boards inside the pneumatic section.
Avoid contact with these PC boards
when performing maintenance inside
the pneumatic section.
The PC boards contain components that are highly
sensitive to static electricity.
Those who come into contact with circuit boards
containing sensitive components must take certain
precautions to avoid damaging the components (ESD
protection).
When working with ESD sensitive components,
always use a grounded wrist band and grounded
work surface. Adequate service tools must also be
used.
PC boards (spare parts) must always be kept in
protective packaging for sensitive electronic devices.
PC boards must not be inserted or removed while
mains power or battery power is applied to the PC
boards.
Remove and insert the PC boards very carefully to
avoid damage to the connectors.
