SIMOVERT MASTER DRIVES Operating Instructions
CAUTION
Components which can be destroyed by electrostatic discharge (ESD)
The converters contain components which can be destroyed by electrostatic discharge. These components can
be easily destroyed if not carefully handled. If you have to handle electronic boards please observe the
following:
♦
Electronic boards should only be touched when absolutely necessary.
♦
The human body must be electrically discharged before touching an electronic board
♦
Boards must not come into contact with highly insulating materials - e.g. plastic foils, insulated desktops,
articles of clothing manufactured from man-made fibers
♦
Boards must only be placed on conductive surfaces
♦
When soldering, the soldering iron tip must be grounded
♦
Boards and components should only be stored and transported in conductive packaging (e.g. metalized
plastic boxes, metal containers)
♦
If the packing material is not conductive, the boards must be wrapped with a conductive packaging material,
e.g. conductive foam rubber or household aluminum foil.
