Service Manual HS-60 2 Operational safety

03/2003 US Issue 2.9 ESD guidelines

Always place the modules on a conductive surface (table with an ESD coating, conductive ESD

foam, ESD bag or container). 2

Do not bring modules near visual display units, monitors or televisions. Keep them at least 10 cm

away from the screen. 2

2.9.4 Measurements and modifications to ESD modules

Do not take measurements on such modules unless 2

– the measuring device is earthed (e.g. via PE conductors) or

– you discharge the measuring head just before taking measurements with a potential-free mea-

suring device (e.g. by touching an unpainted metal part of the controller casing).

Æ Always use an earthed soldering iron if you carry out any soldering work.

2.9.5 Dispatching ESD modules

Æ Always store modules and components in conductive packaging (e.g. metallized plastic bags

or metal sleeves) and dispatch them in conductive packaging.

If the packaging is not conductive, place the modules in a conductive envelope before packag-

ing. (Use ESD bags, domestic aluminum foil or paper, for example. NEVER use plastic bags

or film). 2

Æ If the module has integral batteries, ensure that the conductive packaging does not touch or

short-circuit the battery terminals and, if necessary, first cover the terminals with insulating tape

or material.
