• Use only cable glands/plugs that comply with the requirements for the relevant type of protection.
• Tighten the cable glands in accordance with the torques specified in Transmitter (Page 12).
• Close unused cable inlets for the electrical connections.
• When replacing cable glands use only cable glands of the same type.
• After installation check that the cables are seated firmly.
WARNING
Hazardous contact voltage
Risk of electric shock in case of incorrect connection.
• For the electrical connection specifications, refer to the information in Technical data (Page 21).
• At the mounting location of the device observe the applicable directives and laws for installation of electrical power
installations with rated voltages below 1000 V.
NOTICE
Condensation in the device
Damage to device through formation of condensation if the temperature difference between transportation or storage and
the mounting location exceeds 20 °C (36 °F).
•
Before taking the device into operation let the device adapt for several hours in the new environment.
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 21) or on the nameplate.
