Handling the modules

Therefore, please pay attention to the following guidelines:
• Electronics modules must not be touched unless it is absolutely vital for work to
be done.
• Before touching a module, any static in the body must be discharged. The
easiest way to do this is by touching a conductive, earthed part of the structure
(e.g. bare metal parts of the cubicle, socket earth contact).
• Modules should not be brought into contact with materials that are good
insulators (e.g. plastic foil, insulated desk tops, clothing made from synthetic
fibres).
• Modules should only be laid on conductive surfaces.
• Modules should only be removed or replaced with the power off.
