Do not allow modules with chargeable and highly insulating materials to touch one another, e.g.
plastic films, insulating table surfaces or items of clothing made from synthetic fibers. 2
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
2.8.4 Measurements and modifications to ESD modules
Do not take measurements on such modules unless
È the measuring device is earthed (e.g. via PE conductors) or
È 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).
È Always use an earthed soldering iron if you carry out any soldering work.
2.8.5 Dispatching ESD modules
È 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 pack-
aging. (Use ESD bags, domestic aluminum foil or paper, for example. NEVER use plastic bags
or film). 2
È 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.

1.15.1 Structure of the PCB conveyor
The placement system is supplied with a single conveyor as standard. A dual conveyor is avail-
able as an option. 1
The left or the right side of the PCB conveyor can be used as the stationary side, as required. 1

The conveyor belts are driven by DC motors. The lifting table near the center conveyor clamps the
PCBs in position. The width of the PCB conveyor can be adjusted either 1
– via the menu or
– using the line computer.
