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 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 Regulations and measures
Electronic devices are generally not failsafe. If the programmable logic controller, operating or control device or
uninterruptible power supply fails, the user is responsible for ensuring that connected devices (such as motors)
are brought to a safe state.
When using programmable logic controllers as well as when using operating and monitoring devices as control
systems in conjunction with a Soft PLC (e.g. B&R Automation Runtime or similar product) or Slot PLC (e.g. B&R
LS251 or similar product), the safety measures that apply to industrial controllers (protection by protective equip-
ment such as emergency stops, etc.) must be observed in accordance with applicable national and international
regulations. This also applies to all other connected devices, such as drives.
All work such as installation, commissioning and servicing are only permitted to be carried out by qualified person-
nel. Qualified personnel are persons who are familiar with the transport, installation, assembly, commissioning and
operation of the product and have the appropriate qualifications for their job (e.g. IEC 60364). National accident
prevention regulations must be observed.
The safety guidelines, information about connection conditions (nameplate and documentation) and limit values
specified in the technical data must be read carefully before installation and commissioning and must be strictly
observed.
1.2.5 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
"Protection against electrostatic discharge" on page 6
).
1.2.6 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
