Transport And Storage; Installation; Operation; Protection Against Contact With Electrical Parts - B&R Automation PC 3100 User Manual

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) must be observed in accordance with applicable national and international regu-
lations. 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.

2.4 Transport and storage

During transport and storage, devices must be protected against undue stress (mechanical stress, temperature,
humidity, aggressive atmosphere).

2.5 Installation

• The devices are not ready for use and must be installed and wired according to the requirements of this
documentation in order to comply with EMC limit values.
• Installation must be carried out according to the documentation using suitable equipment and tools.
• Devices are only permitted to be installed in a voltage-free state and by qualified personnel. The control
cabinet must first be disconnected from the power supply and secured against being switched on again.
• 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).

2.6 Operation

2.6.1 Protection against contact with electrical parts

In order to operate programmable logic controllers, operating and monitoring devices and uninterruptible power
supplies, it is necessary for certain components to carry dangerous voltages over 42 VDC. Touching one of these
components can result in a life-threatening electric shock. There is a risk of death, serious injury or damage to
property.
Before switching on programmable logic controllers, operating and monitoring devices and uninterruptible power
supplies, it must be ensured that the housing is properly connected to ground potential (PE rail). The ground
connection must also be made if the operating and monitoring device and uninterruptible power supply are only
connected for testing purposes or only operated for a short time!
Before switching on, live parts must be securely covered. All covers must be kept closed during operation.

2.6.2 Ambient conditions - Dust, moisture, aggressive gases

The use of operating and monitoring devices (e.g. industrial PCs, Power Panels, Mobile Panels) and uninterruptible
power supplies in dusty environments must be avoided. This can otherwise result in dust deposits that affect the
functionality of the device, especially in systems with active cooling (fans), which may no longer ensure sufficient
cooling.
The presence of aggressive gases in the environment can also result in malfunctions. In combination with high
temperature and relative humidity, aggressive gases – for example with sulfur, nitrogen and chlorine components
– trigger chemical processes that can very quickly impair or damage electronic components. Blackened copper
surfaces and cable ends in existing installations are indicators of aggressive gases.
When operated in rooms with dust and condensation that can endanger functionality, operating and monitoring
devices such as Automation Panels or Power Panels are protected on the front against the ingress of dust and
moisture when installed correctly (e.g. cutout installation). The back of all devices must be protected against the
ingress of dust and moisture, however, or the dust deposits must be removed at suitable intervals.
