• Only use certified cable entries that are suitable for the application.
Observe selection criteria according to IEC/EN 60079-14 .
• When the measuring device is connected, attention must be paid to
the type of protection at the transmitter .
• In potentially explosive atmospheres:
– Do not disconnect the electrical connection of the power supply
circuit when energized.
– Do not open the connection compartment cover when energized.
Ex ec type of protection
• In potentially explosive atmospheres: Do not disconnect the electrical
connection of the power supply circuit.
• Seal unused entry glands with approved sealing plugs that correspond
to the type of protection. The plastic transport sealing plug does not
meet this requirement and must therefore be replaced during
installation.
• Only use certified cable entries or sealing plugs. The metal sealing
plugs supplied meet this requirement.
• Equipment in type of protection Ex ec or Ex nA shall be installed
using a transient protection not exceeding 140% of the peak rated
voltage value at the power supply terminals and IO terminals.
• For measuring devices with order code "Housing", option B "Stainless,
hygienic" tighten the connection compartment cover hand-tight and
then tighten it further 45°.
• Transmitter housings of measuring devices with order code "Housing",
option B "Stainless, hygienic" must be installed in a way that they are
not exposed to UV radiation or artificial light.
Intrinsic safety
Observe the guidelines for interconnecting intrinsically safe circuits
(e.g. IEC/EN 60079-14, Proof of Intrinsic Safety).
Potential equalization
• Integrate the device into the local potential equalization .
• If the ground connection has been established via the pipe as
specified, it is also possible to integrate the sensor into the potential
equalization system via the pipe.
