ESD Protection

ESD (Electrostatic Sensitive Devices)
For every electronic device, ESD protection is important.
This also applies to the MiniCoders. Do not touch electronic
devices unless servicing is required. This is particularly im-
portant for connector pins and loose wires. Which precau-
tions are required in the particular case is dependant on to
local situation. EN 100015-1 (CECC 00015-1) gives a com-
prehensive overview on possible solutions.

Notes on electromagnetic compatibility (EMC)

EMC (ElectroMagnetic Compatibility)
To improve the electromagnetic environment please observe the following installation
advice:
 Only use connectors with metal housing or a housing made of metallised plastic
and screened cables; make sure to set up a contact between the screening and the
connector housing.
 The screenings must have large-surface contact.
 Keep all unscreened lines as short as possible.
 Provide for earth connections being as short as possible and having a large cross-
section (e.g. low-inductance metal-alloy tape, flat-band conductor).
 Keep the earth connection cable of the MiniCoder as short as possible.
 If there are potential differences between machine and electronic ground straps:
Make sure that equalizing currents can flow via the cable shielding. For this purpose,
lay a large diameter voltage equalizing cable or use cables with separate two-ply
shielding, although the shielding should only be applied on one side.
The machine manufacturer has to develop an overall screening concept regarding
all the components used.

ESD Protection
In most situations, a grounded working surface together with
ESD wrist straps will give sufficient protection.
We do recommend to check the ESD equipment regularly.
