2.2 Safety in the individual operating phases

When installing the control unit and during operation, the following safety instructions must be

observed.

Danger of Electrocution!

Before working on the device, switch off all power supplies used. The

electrical cables must be laid according to the respective national

regulations (in Germany VDE 0100). The measuring lines must be laid

separately from the mains leads. The connection between the connection

for the functional earth (in the respective device carrier) and a protective

conductor must be established.

Danger of Electrocution!

Any interruption of the protective conductor in the device carrier can lead

to the device becoming dangerous. Intentional interruptions are not

permitted. If it is suspected that safe operation is no longer possible, the

device is to be decommissioned and secured against unintentional

operation.

Danger of Electrocution!

Do not open the device while it is live! When opening the devices or

removing covers and parts, live parts may be exposed. Connecting points

can also be live!

WARNING!

The device must never be put into operation despite any visible damage.

WARNING!

During installation, commissioning, maintenance and troubleshooting,

observe the accident prevention regulations applicable to your system,

e.g. DGUV Regulation 3 "Electrical installations and equipment".

WARNING!

Clean dirty contacts with oil-free compressed air or with spirit and a lint-

free cloth.

Warning of material damage caused by electrostatic charge!

Observe the safety measures according to BS EN 61340-51/-3 to avoid

electrostatic discharge!

Explosion Prevention!

The HE 5712 Compact (Fig. 1)is suitable for use in explosion zone 22.

Before opening the device, it is essential to ensure that no explosive

environmental conditions, such as dust generation, exist

Troubleshooting!

At the beginning of troubleshooting, all possible sources of faults on

additional devices or supply lines (measuring lines, wiring, downstream

devices) should be taken into consideration. If the fault was not found

after checking these points, we recommend sending the device to the

supplier.

Decommissioning!

Switch off the power supply on all poles if the device is to be

decommissioned. Secure the device against unintentional operation!

If the device is connected to other devices and / or equipment, the effects

must be considered and appropriate precautions taken before switching

off.

The following special regulations must be observed:

Connect cables professionally in glands.

Close not needed housing bores with locking bolts.

Cleaning of the housing is only permitted with moist cleaning agents to avoid static

charging.

Cleaning is necessary to prevent increased dust generation on the device.

Operation under voltage, in zone 22, only in closed state.

Before closing, ensure that the device housing is free of dust
