General Prerequisites For Operating The Devices - Festo MPS 8046325 Manual

1 General prerequisites 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 of the laboratory or
the classroom.

The laboratory or classroom must be secured so that operating voltage and compressed air supply
cannot be activated by any unauthorized persons, for example with:
– Key switches
– Lockable on-off valves

The laboratory or classroom must be protected by residual current devices (RCDs).
– Type B residual current circuit breakers with a residual current 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 been trained in electrical engineering,
knows 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).

The device is not equipped with an integrated fuse unless specified otherwise in the technical data.
