General Requirements For Operating The Devices; Pictograms - Festo MPS Serie Manual

1 General requirements for operating the devices

The laboratory or the classroom must be equipped with the following devices:
•
An emergency-off device must be provided.
– At least one emergency-off device must be located within, and one outside the laboratory or
the classroom.
•
The laboratory or classroom must be secured so that the operating voltage and compressed air supply
cannot be activated by any unauthorised persons, for example by means of:
– A key switch
– A lockable on-off valve
•
The laboratory or classroom must be protected by residual current devices (RCDs).
– Type B residual current circuit breakers with a residual current rating of ≤ 30 mA
•
The laboratory or classroom must be protected by overcurrent protection devices.
– Fuses or circuit breakers
•
The laboratory or classroom must be overseen by a supervisor.
– A supervisor is a qualified electrician or a person who has received appropriate instruction,
has knowledge of the respective safety requirements and safety regulations and
whose training has been documented accordingly.
•
No damaged or defective devices may be used.
– Damaged devices must be barred from further use and removed from the laboratory or classroom.
General requirements for safe operation of the devices:
•
Do not lay cables over hot surfaces.
– Hot surfaces are identified with a corresponding warning symbol.
•
Maximum permissible current loads for cables and devices must not be exceeded.
– Always compare the current ratings of the device, the cable and the fuse.
– In the event that these are not the same, use a separate upstream fuse in order to
provide appropriate overcurrent protection.
•
Devices with an earth terminal must always be grounded.
– If an earth connection (green-yellow laboratory socket) is available, it must always be
connected to protective earth. Protective earth must always be connected first (before voltage),
and must always be disconnected last (after voltage).
•
If not otherwise specified in the technical data, the device is not equipped with an integrated fuse.
