2.2 Signal words
DANGER!
Indicates an imminently hazardous high risk situation, which, if not avoided, will result in death
or serious injury.
WARNING!
Indicates a potentially hazardous medium risk situation, which, if not avoided, could result in
death or serious injury.
CAUTION!
Indicates a hazardous low risk situation, which, if not avoided, could result in minor or
moderate injury.
2.3 Safety in the individual operating phases
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 laid
separately from the power lines. Connect the protective earth connector
(in the respective equipment carrier) to the protective earth conductor.
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 the accident prevention regulations applicable to 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!

Power Connection!
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.
Troubleshooting!
At the beginning of troubleshooting, all possible sources of faults on
additional devices or supply lines (measuring lines, wiring and
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.
2.4 Special Regulations
Note!
Lock cable screw connections that are not needed with a locking bolt,
casing bores with dummy plugs.
Warning of material damage caused by electrostatic charge!
The device must be cleaned regularly to prevent increased dust
generation on the device.
Cleaning of the housing only permitted with moist cleaning materials to
avoid static charging!

5.2 Opening the device
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! Disconnect the device
from the power supply!
The opening and closing works without screws by means of hinge technology. A flat-tip
screwdriver is needed to open the device. Apply the screwdriver to the respective position on
the housing lid, in order to lift up the hinge (see Figure 4).
Note!
Make sure to move the screw driver to the right to open the hinge (see
Figure 4). If the screwdriver is moved to the left, the housing cover can
be damaged.
Open the housing cover to the left up to an angle of 105°.
Optionally, the housing cover can be closed with 4 screws to prevent the device from
unauthorised access (for further information, please contact the HESCH service, see chapter
8 Maintenance and disposal).
The screwless hinge closure is recommended for quick service access.
Open the housing cover to the left ( figure shows a device with identical housing)
