1.2.3.2 Regulations for proper ESD handling
Electrical assemblies with housing
•
Do not touch the connector contacts on the device (bus data contacts).
•
Do not touch the connector contacts of connected cables.
•
Do not touch the contact tips on circuit boards.
Electrical assemblies without housing
The following applies in addition to "Electrical assemblies with housing":
•
All persons handling electrical assemblies and devices in which electrical assemblies are installed must
be grounded.
•
Assemblies are only permitted to be touched on the narrow sides or front plate.
•
Always place assemblies on suitable surfaces (ESD packaging, conductive foam, etc.).
Information: Metallic surfaces are not suitable surfaces!
•
Assemblies must not be subjected to electrostatic discharges (e.g. due to charged plastics).
•
A minimum distance of 10 cm from monitors or television sets must be maintained.
•
Measuring instruments and devices must be grounded.
•
Test probes of floating potential measuring instruments must be discharged briefly on suitable grounded
surfaces before measurement.
Individual components
•
ESD protective measures for individual components are implemented throughout B&R (conductive floors,
shoes, wrist straps, etc.).
•
The increased ESD protective measures for individual components are not required for handling B&R
products at customer locations.
1.2.4 Transport and storage
During transport and storage, devices must be protected against undue stress (mechanical stress, temperature,
humidity, aggressive atmosphere).
Devices contain components sensitive to electrostatic charges that can be damaged by improper handling. It is
therefore necessary to provide the required protective measures against electrostatic discharge when installing or
removing these devices (see
"Protection against electrostatic discharge" on page 6
).
1.2.5 Installation
•
Installation must be performed according to this documentation using suitable equipment and tools.
•
Devices are only permitted to be installed by qualified personnel when the power is switched off.
•
General safety regulations and national accident prevention regulations must be observed.
•
The electrical installation must be carried out in accordance with relevant regulations (e.g. wire cross sec-
tion, fuse protection, protective ground connection).
•
Take the necessary protective measures against electrostatic discharge (see
"Protection against electro-
static discharge" on page 6
).
