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

4.1.1 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 4.1.2.

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. Textured or rough surfaces are not recommended and may limit the effectiveness of the gasket seal provided.

Optional hardware accessories are available that allow for panel- or pipe-mount. Refer to Section 15 for ordering information.

Transmitter Multiparameter M400 14

4.1.2 Installation procedure

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. – Mount rear housing to wall using appropriate mounting hardware for wall surface. Be sure

it is level and securely fastened and the installation adheres to any and all clearance

dimensions required for transmitter service and maintenance. – Insert two black protective covers (supplied with the M400 transmitter) over the ﬁxing

hardware and into the space on the inside back cover, as shown in the drawing below.

This is necessary to maintain unit integrity. – Replace the front housing to the rear housing. The unit is ready to be wired.

For Pipe Mount: – Use only manufacturer-supplied components for pipe-mounting the M400 transmitter and

install per the supplied instructions. See section 15 for ordering information.

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 M400 models is provided for power connection. All M400 models are designed to operate from a 20–30 VDC or a 100 to 240 VAC power source. Refer to speciﬁcations for power requirements and ratings and size power wiring accordingly (AWG 14, wire cross-section ≤ 2.5 mm2).

The terminal block for power connections is labeled ”Power” on the rear panel of the transmitter. One terminal is labeled – N for the Neutral wire and the other + L for the Line (or Load) wire. The terminals are suitable for single wires and ﬂexible leads up to 2.5 mm2 (AWG 14). There is no earth ground terminal on the transmitter. For this reason the internal power wiring within the transmitter is double insulated and the product label designates this using the h symbol.
