Transmitter pH M300 1 V20 7 Introduction Statement of Intended Use - The M300 pH transmitter is a single channel online process instrument for measuring pH 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. The menu structure allows the operator to modify all operational parameters by using keys on the front panel.
Transmitter pH M300 V20 8 WARNINGS: Installation of cable connections and servicing of this product require access to shock hazard voltage levels. Main power and relay contacts wired to separate power source must be disconnected before servicing. Main power must employ a switch or circuit breaker as the disconnecting device for the equipment. Electrical installation must be in accordance with the National Electrical Code and/or any other applicable national or local codes.
Transmitter pH M300 3 V20 9 Unit overview M300 models are available in both a 1/4DIN and 1/2DIN case size. The 1/4DIN is a panel-mount only design and the 1/2DIN models provides an integral NEMA 4X/IP65 housing for wall-, pipe- or panel-mount. 3.

Transmitter pH M300 V20 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 pH M300 4.1.2 - V20 15 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 pH M300 4.1.3 V20 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 pH M300 4.1.4 - V20 17 Installation procedure - 1/2DIN models 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 pH M300 4.2 V20 18 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 240 VAC power source.
