WARNING
Missing PE/ground connection
Risk of electric shock.
Depending on the device version, connect the power supply as follows:
● Power plug: Ensure that the used socket has a PE/ground conductor connection. Check
that the PE/ground conductor connection of the socket and power plug match each other.
● Connecting terminals: Connect the terminals according to the terminal connection
diagram. First connect the PE/ground conductor.
NOTICE
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 (36 °F) higher.
WARNING
Improper power supply
Risk 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, in Technical data (Page 215) or on
the nameplate.
WARNING
Unsafe extra-low voltage
Risk of explosion in hazardous areas due to voltage flashover.
● Connect the device to an extra-low voltage with safe isolation (SELV).
WARNING
Lack of equipotential bonding
Risk of explosion through compensating currents or ignition currents through lack of
equipotential bonding.
● Ensure that the device is potentially equalized.
Exception: It may be permissible to omit connection of the equipotential bonding for devices
with type of protection "Intrinsic safety Ex i".
