2.3 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 cables must be laid
separately from the power lines. The connection between the connector
for the functional earth (in the respective equipment carrier) and a
protective earth must be established.
Danger of Electrocution!
Any interruption of the protective earth in the equipment carrier can result
in the device becoming a hazard. Intentional interruptions are not
permitted. If there is a suspicion that it is no longer possible to operate
the device safely, it must be shut off and secured against being
unintentionally switched on.
Danger of Electrocution!
Do not open the device when it is connected to the voltage! When
opening the devices or removing covers and parts, live parts may be
exposed. Connection points can also be live!
Attention!
The device must never be put into operation even if damage is
recognisable.
Attention!
During installation, commissioning, maintenance and troubleshooting,
observe accident prevention regulations for your system, e.g. DGUV
Regulation 3 "Electrical installations and equipment".
Attention!
Clean dirty contacts with oil-free compressed air or ethyl alcohol 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!
Electrical connection!
The cable shielding belongs to the measurement earth.
The effects of interference fields can be prevented through use of twisted
and screened measuring lines.
The respective connection diagrams / connection designs for the devices
apply

HE 5710 / 5711 Operating Instructions
# 371814 | Version 1.4
Explosion Prevention! (for ATEX approved devices only!)
This device (the version with the Makrolon housing) is suitable for
operation in explosion Zone 22 with the lid closed (where an explosive
atmosphere may arise due to electrically conductive dusts).
Prior to opening the device, one must ensure that there are no explosive
ambient conditions, such as dust formation. The special regulations
governing operation in an Ex-area must be observed.
Fuse failure!
First determine the causes for the failure and remove them.
Only use fuses which have the same specification as the original type as a
replacement.
Repaired fuses or short circuiting are not permissible.
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 is 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 being unintentionally
switched on!
If the device is linked to other devices and/or equipment, consider the
impacts and take appropriate precautions before switching it off.

With ATEX:
Without ATEX:
The following special regulations must be observed:
Connect the cable firmly to the glands.
Housing bores not required must be closed professionally with sealing bolts.
The ATEX certification only maintains its validity if the installation is carried out correctly by a
professional under the safeguarding of the protection class specified on the marking.
Cleaning of the housing is only permitted with moist cleaning materials to avoid static charging.
The device must be cleaned regularly to prevent increased dust generation on the device.
Operation under voltage in EX zone 22 only in closed state.
Before closing, ensure that the device housing is free of dust.
