4.5 Connection of Protective Earth Conductor/Grounding
ATTENTION!
In order to ensure that the device can be operated safely and to meet the requirements of
IEC 62368-1, the device must be correctly connected to the protective earth conductor via
the protective earth connection terminal.
If an external earth terminal is provided on the housing, it must be connected to your
bonding busbar (grounding busbar). The parts required to attach the device to a
grounding busbar are not included with the shipped product.
Note:
Please use a grounding cable with a core cross-section of
≥
1.5 mm
2
Always ensure that the connection is properly crimped!
4.6 Safety during Operation
WARNING!
Avoiding Short-Circuits
Protect the device against all ingress of solid objects or liquids. Ingress presents a risk of
electric shock or short-circuiting!
Ventilation Slots
Ensure that the ventilation slots are clean and uncovered at all times. Blocked ventilation slots
may cause heat to be trapped in the system, resulting in overheating. This may cause your device to
malfunction or fail.
Appropriate Usage
The device is only deemed to be appropriately used and EMC limits (electriomagnetic compatibility)
are only deemed to be observed if the chassis cover is properly fitted (thus ensuring that the device
is properly cooled, fire-safe, and shielded against electrical, magnetic and electromagnetic fields).
Switching the Device Off in the Event of a Malfunction or when Repairs are Required
It is not sufficient to simply switch off the device itself in order to disconnect the power supply.
If the device is malfunctioning, or if repairs become necessary, the device must be isolated from all
power supplies immediately.
To do so, follow the procedure below:
- Switch off the device from the unit itself.
- Pull out all power supply plugs.
- Inform the person or department responsible for your electrical installation.
- If your device is connected to an Uninterruptible Power Supply (UPS), it will remain
operational even after pulling the UPS power cable from the mains socket. In this case, you
will need to shut down your UPS in accordance with the user documentation of your UPS
system.
