Transmitter O2 M300 1 Introduction Statement of Intended Use – The M300 O2 transmitter is a single-channel online process instrument for measuring conductivity or resistivity of fluids. It will interface with a variety of different Mettler-Toledo sensors, which connect to the transmitter using cables of varied lengths. A large four line backlit Liquid Crystal Display conveys measuring data and setup information.
Transmitter O2 M300 The following is a list of general safety instructions and warnings. Failure to adhere to these instructions can result in damage to the equipment and/or personal injury to the operator. – The M300 Transmitter should be installed and operated only by personnel familiar with the transmitter and who are qualified for such work. – The M300 Transmitter must only be operated under the specified operating conditions (see section 16).
Transmitter O2 M300 9 3 Unit overview M300 models are available in both a 1/ DIN and 1/2DIN case size. The 1/ DIN is a panelmount only design and the 1/2DIN models provides an integral IP65 housing for wall-, or pipe-mount. 3.

Transmitter O2 M300 4 Installation instruction 4.1 Unpacking and inspection of equipment 14 Inspect the shipping container. If it is damaged, contact the shipper immediately for instructions. Do not discard the box. If there is no apparent damage, unpack the container. Be sure all items shown on the packing list are present. If items are missing, notify Mettler-Toledo immediately 4.1.
Transmitter O2 M300 15 4.1.2 – – – – – – – – Installation procedure – 1/4DIN models Make cutout in panel (see dimensions cutout drawing). Be sure surface surrounding cutout is clean, smooth and free of burrs. Slide face gasket (supplied with transmitter) around transmitter from the back of the unit. Place transmitter into cutout hole. Be sure there are no gaps between the transmitter and panel surface.
Transmitter O2 M300 4.1.3 16 Panel cutout dimensional information – 1/2DIN models 1/2DIN Model transmitters are designed with an integral rear cover for stand-alone wall mount installation. The unit may also be wall mounted using the integral rear cover. See installation instructions in Section 4.1.4. Below are cut-out dimensions required by the 1/2DIN models when mounted within a flat panel or on a flat enclosure door. This surface must be flat and smooth.
Transmitter O2 M300 4.1.4 17 Installation procedure – 1/2DIN models For Wall Mount: – Remove rear cover from front housing. – Start by unscrewing the four screws located on the face of the transmitter, in each corner. This allows the front cover to swing away from the rear housing. – Remove the hinge-pin by squeezing the pin from each end. This allows the front housing to be removed from the rear housing – Drill out wall-mount breakthroughs in the rear housing.
Transmitter O2 M300 18 4.2 Connection of power supply All connections to the transmitter are made on the rear panel of all models. Be sure power to all wires is turned off before proceeding with the installation. High voltage may be present on the input power wires and relay wires. A two-terminal connector on the rear panel of all M300 models is provided for power connection. All M300 models are designed to operate from a 20–30 VDC or a 100 to 2 0 VAC power source.
