NOTICE
If the O-ring gasket is seated incorrectly or damaged, this
may have an adverse effect on the housing protection
class.
Follow the instructions in Opening and closing the terminal
box on page 22 to open and close the housing safely.
Connection procedure for integral mount design: Carry out steps
A
to
C
.
To this end, comply with the information below:
• Route the power supply cable through the cable entry on
the left-hand side into the terminal box.
• Route the cables for the analog and digital outputs
through the cable entry on the right-hand side into the
terminal box.
• Connect the cables in accordance with the connection
diagrams. Connect the cable shields to the provided
grounding clamp in the terminal box.
• Connect the equipotential bonding system (PA) with the
ground terminal at the terminal box.
• Use ferrules for making the connections.
Note
• Adhere to the limit values of the power supply in accordance
with the information on the name plate.
• Observe the voltage drop for large cable lengths and small
conductor cross-sections. The voltage at the terminals of the
device may not down-scale the minimum value required in
accordance with the information on the name plate.
The power supply is connected to terminal L (phase), N (zero), or
1+, 2
− , and PE.
A circuit breaker with a maximum rated current of 16 A must be
installed in the power supply line.
The wire cross-sectional area of the power supply cable and the
circuit breaker used must comply with VDE 0100 and must be
dimensioned in accordance with the current consumption of the
flowmeter measuring system. The cables must comply with IEC
227 and/or IEC 245.
The circuit breaker must be located near the device and marked
as being associated with the device.
Connect the transmitter and sensor to functional earth.
