1 General requirements for operating the devices

The laboratory or the classroom must be equipped in accordance with EN 50191:

An emergency off device must be provided.
– At least one emergency off device must be located within, and one outside of the test area.

The test area must be secured against unauthorised start-up.
– For example with a key switch

The test area must be protected by residual current devices (RCDs).
– Type B residual current circuit breaker with a residual current rating of ≤ 30 mA

The test area must be protected by overcurrent protection devices.
– Fuses or circuit breakers

The test area 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 accordingly documented.

No damaged or defective devices may be used.
– Damaged devices must be barred from further use and removed from the test area.
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.
