WARNING
Missing PE/ground connection
Danger of electric shock.
Depending on the device version, connect the power supply as follows:
● Connecting terminals: Connect the terminals according to the terminal connection diagram. First connect the PE/ground
conductor.
CAUTION
Ambient temperature too high
Damage to cable sheath.
● At an ambient temperature ≥ 60 °C (140 °F), use heat-resistant cables suitable for an ambient temperature at least 20
°C (68 °F) higher.
WARNING
Improper power supply
Danger of explosion in hazardous areas as result of incorrect power supply, e.g. using direct current instead of alternating
current.
● Connect the device in accordance with the specified power supply and signal circuits. The relevant specifications can
be found in the certificates found in the operating instructions or on the nameplate.
WARNING
Lack of equipotential bonding
Danger of explosion through compensating currents or ignition currents through lack of equipotential bonding.
● Ensure that the device is potentially equalized.
WARNING
Unprotected cable ends
Danger of explosion through unprotected cable ends in hazardous areas.
● Protect unused cable ends in accordance with IEC/EN 60079-14.
WARNING
Improper laying of shielded cables
Danger of explosion through compensating currents between hazardous area and the non-hazardous area.
● Only ground shielded cables that run into the hazardous area at one end.
● If grounding is required at both ends, use an equipotential bonding conductor
WARNING
Insufficient isolation of non-intrinsically safe and intrinsically safe circuits
Danger of explosion in areas subject to explosion hazard.
● When connecting intrinsically safe and non-intrinsically safe circuits ensure that isolation is carried out properly in
accordance with IEC / EN 60079-14.
● Make sure that you observe the test certification applicable in your country.
