3.3 Transport
Signal converter
• Do not lift the signal converter by the cable glands.
Measuring sensor
• Do not lift the measuring sensor by the connection box.
• Use hoisting belts only.
• To transport flange devices, use lifting straps. Wrap these around both process connections.
INSTALLATION 3
Figure 3-1: Transport
3.4 Installation requirements signal converter
• Allow 10…20 cm / 3.9…7.9" of space at the sides and rear of the signal converter to permit
free air circulation.
• Protect signal converter against direct solar radiation, install a sunshield if necessary.
• Signal converters installed in switchgear cabinets require adequate cooling, e.g. by fan or
heat exchanger.
• Do not expose the signal converter to intense vibration.
3.5 Installation requirements sensor
To secure the optimum functioning of the flowmeter, please note the following observations.
The OPTISONIC 7300 is designed for the measurement dry gasflow. Excess of liquids may
disturb the acoustic signals and should thus be avoided.
The following guidelines should be observed in case occasional small amounts of liquids are to
be expected:
• Install the flow sensor in a horizontal position in a slightly descending line.
• Orientate the flow sensor such that the path of the acoustic signal is in the horizontal plane.
For exchanging the transducers, please keep a free space of 1 m / 39" around the transducer.

Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.
4.2 Signal cable (remote versions only)
The flow sensor is connected to the signal converter via the signal cable(s). A flow sensor with
one acoustic path, 1 cable is required. A flow sensor with two acoustic paths, 2 cables are
required.

4.3 Power supply
WARNING!
When this device is intended for permanent connection to the mains.
It is required (for example for service) to mount an external switch or circuit breaker near the
device for disconnection from the mains. It shall be easily reachable by the operator and marked
as the disconnecting the device for this equipment.
The switch or circuit breaker and wiring has to be suitable for the application and shall also be in
accordance with the local (safety) requirements of the (building) installation
(e.g. IEC 60947-1 / -3)
INFORMATION!
The power terminals in the terminal compartments are equipped with additional hinged lids to
prevent accidental contact.

2 24 VAC/DC (AC: -15% / +10%; DC: -25% / +30%), 22 VA or 12 W
DANGER!
The device must be grounded in accordance with regulations in order to protect personnel
against electric shocks.
100…230 VAC
• Connect the protective ground conductor PE of the mains power supply to the separate
terminal in the terminal compartment of the signal converter.
• Connect the live conductor to the L terminal and the neutral conductor to the N terminal.
24 VAC/DC
• Connect a functional ground FE to the separate U-clamp terminal in the terminal
compartment of the signal converter.
• When connecting to functional extra-low voltages, provide a facility for protective separation
(PELV) (VDE 0100 / VDE 0106 and/or IEC 364 / IEC 536 or relevant national regulations).

4.4 Laying electrical cables correctly
Figure 4-4: Protect housing from dust and water
1 Lay the cable in a loop just before the housing.
2 Tighten the screw connection of the cable entry securely.
3 Never mount the housing with the cable entries facing upwards.
4 Seal cable entries that are not needed with a plug.
