Safety
instructions
This product is designed for use in accordance with EN IEC 61010-1 for Installation Category 2 and
Pollution Degree 2. Hazardous voltages are present within this product during normal operation. The
product is designed for Protection Class I and should never be operated without protective earthing.
The product shall also never be operated with covers removed unless equivalent protection of the
operator and its environment from accidental contact with hazardous internal voltages is provided.
Always follow basic and local safety precautions when using this product to reduce risk of injury from
electrical shock, spread of fire or other dangerous situations.
Converter terminal box
•
The converter terminal box is accessible after removing the rear (blind) cover of the electronics
section using the special wrench supplied with the flowmeter.
•
Do not damage the screw thread and the gasket, never allow dirt to accumulate, and make sure
that the screw thread is well greased, using Teflon grease at all times. A damaged gasket must
be replaced immediately!
•
Do not cross or loop the cables in the terminal box of the signal converter. Use separate cable
entries for power supply and signal cables.
•
Special regulations apply to installation in hazardous areas (see installation instructions for
hazardous areas).

This instrument 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
product for disconnection from the mains. It must be easily reachable by the
operator and marked as the disconnecting device for this product.
The switch or circuit breaker has to be suitable for the application and shall also be
in accordance with to local (safety) requirements and of the building installation.
(IEC 60947-1/-3).
•
The protective conductor clamp terminal size M5, press-fitted in the terminal
compartment (near the main connection terminals), shall always to be connected
to the protective earth conductor of the mains supply. Conductors up to 4 mm²
(11 AWG) be connected to this terminal. The diameter of the conductors of the
mains supply, including the protective earth conductor shall be in accordance with
