General prerequisites for operating the devices

General requirements for safe operation of the devices:
• National regulations for operating electrical systems and equipment must be observed in commercial
facilities.
•
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.
•
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.
– If 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 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 banned from further use and removed from the laboratory or classroom.
– Damaged connecting cables, pneumatic tubing and hydraulic hoses represent a safety
risk and must be removed from the laboratory or classroom.
