Transport And Storage; Installation; Operation; Protection Against Touching Electrical Parts - B&R Panel PC 2100 User Manual

General information
When using programmable logic controllers or operating/monitoring devices as control systems in connection with
a Soft PLC (e.g. B&R Automation Runtime or comparable product) or Slot PLC (e.g. B&R LS251 or comparable
product), safety precautions relevant to industrial control systems (e.g. the provision of safety devices such as
emergency stop, etc.) must be observed in accordance with applicable national and international regulations. This
also applies to all other devices connected to the system, such as drives.
All tasks such as the installation, commissioning and servicing of devices are only permitted to be carried out by
qualified personnel. Qualified personnel are those familiar with the transport, mounting, installation, commissioning
and operation of devices who also have the appropriate qualifications to perform these tasks (e.g. IEC 60364).
National accident prevention regulations must be observed.
The safety notices, information about connection conditions (nameplate and documentation) and limit values spec-
ified in the technical data must be read carefully before installation and commissioning and are to be observed
in all cases.

1.2.4 Transport and storage

During transport and storage, devices must be protected against undue stress (mechanical loads, temperature,
moisture, corrosive atmospheres, etc.).

1.2.5 Installation

• Devices are not ready for use immediately upon delivery. They must be installed and wired according to
the requirements of this documentation in order for EMC limit values to be observed.
• Installation must be performed according to this documentation using suitable equipment and tools.
• Devices are only permitted to be installed by qualified personnel and when the power is switched off. Before
installation, voltage to the control cabinet must be switched off and prevented from being switched on again.
• General safety guidelines and national accident prevention regulations must be observed.
• Electrical installation must be carried out in accordance with applicable guidelines (e.g. wire cross sections,
fuses, protective ground connections).

1.2.6 Operation

1.2.6.1 Protection against touching electrical parts

To operate programmable logic controllers, operating/monitoring devices and uninterruptible power supplies, cer-
tain components must carry dangerous voltage levels over 42 VDC. Touching one of these components can result
in a life-threatening electric shock. This could lead to death, severe injury or damage to property.
Before switching on programmable logic controllers, operating/monitoring devices or the uninterruptible power
supply, it must be ensured that the housing is properly connected to ground (PE rail). Ground connections must
also be established when the operating/monitoring device or uninterruptible power supply is connected for test
purposes or only being operated for a short period of time!
Before switching on the device, all voltage-carrying components must be securely covered. During operation, all
covers must remain closed.

1.2.6.2 Environmental conditions - Dust, moisture, corrosive gases

The use of operating/monitoring devices (e.g. industrial PCs, Power Panels, Mobile Panels) and uninterruptible
power supplies in very dusty environments must be avoided. The collection of dust on devices can affect function-
ality and may prevent sufficient cooling, especially in systems with active cooling (fans).
The presence of corrosive gases can also result in impaired functionality. When combined with high temperature
and humidity, corrosive gases – e.g. with sulfur, nitrogen and chlorine components – can induce chemical reactions
that can damage electronic components very quickly. The presence of corrosive gases is indicated by blackened
copper surfaces and cable ends on existing installations.
When operated in dusty or moist environments that could potentially impair functionality, operating/monitoring
devices such as the Automation Panel and Power Panel are protected on the front against the ingress of dust
or moisture when installed properly (e.g. cutout installation). The back of all devices must be protected from the
ingress of dust and moisture, however; any collected dust must be removed at suitable intervals.
