1.1 Product overview

The SIMATIC HMI device "MP 377 15" Touch daylight readable" offers a special display and
touch technology. This technology offers a brighter display that lets operators monitor and
operate even under very bright light conditions. Good readability is ensured even in direct
sunlight due to the transflective properties of the display. You can dim the backlighting of the
display on the display itself as well as externally and centrally via process value (tag), for
example by means of a potentiometer via the PLC. This means you can use the panel in
control cabins for drilling rigs and in control stations onboard ships.

You can operate the HMI device outdoors if it is installed in a suitable control cabinet. The
necessary, extended ambient temperature range during operation can be created with the
help of active heating and cooling in the control cabinet. We recommend that you consult an
experienced control cabinet designer for appropriate sizing. Intelligent control of heating and
cooling is available with the retrofit panel option "TEK - Temperature Extension Kit".

Certifications are in preparation for operation in the Oil&Gas industry as well as applications
in shipbuilding. These include ATEX Zone 2/22, Class I, Div. 2 as well as country-specific
shipbuilding certificates.

The display offers a large viewing angle that makes for fatigue-free operating and
monitoring. Mounted fans make it possible that you can install the HMI device vertically as
well as inclined in a control cabinet.

Operating conditions for Zones 2 and 22

The following operating conditions apply for Zones 2 and 22:

● The HMI device must be installed in a control cabinet. The control cabinet must meet the

following in accordance with EN 60529:
– Protection type IP54 or higher for Zone 2
– Protection type IP5x or higher for Zone 22 in case of non conductive dust
– Protection type IP6x or higher for Zone 22 in case of conductive dust
You must install the HMI device so that you provide at least protection type IP54 or IP5x

to EN 60529 on the front of the device. Consult the operating instructions of control
cabinet and HMI device for this purpose.

Make allowances for the operating and ambient conditions under which you operate the
HMI device. A manufacturer's declaration must be provided for the control cabinet in
accordance with EC Directive 94/9, stating it is fit for purpose.

● The ambient temperature range is 0 °C ≤ T ≤ 50 °C. Under these conditions, the HMI

device will satisfy temperature class Tx for category 3G and support a maximum surface
temperature of xx °C for category 3D. (x ... Temperature value, see design examination
certificate).

Refer to the operating instructions for details of limitations resulting from the ambient
temperature range.

● In situations where the temperature on the cable at the cable inlet of the control cabinet

exceeds a temperature of 70 °C, or where the temperature on the wire branching point
exceeds 80 °C under operating conditions, the temperature specifications of the cables
must match the actually measured temperatures.

● Put measures in place to ensure the rated voltage is not exceeded.

Any transient interference voltages above the rated value must not exceed 40 %.

● Protect the HMI device from mechanical loads > 7 J and the display from mechanical

loads > 4 J.

● Ensure that the atmosphere is not explosive during servicing.

Measures that impair or remove the protection type of the HMI device are not permitted
while the system is in operation.

● If the HMI device was dismantled, check the mounting seal for damage before

reassembling the HMI device. A damaged, porous or used mounting seal no longer
meets the requirements of the protection type. In this case, the mounting seal must be
replaced.

● Turn off the HMI dev

ice and the entire electrical installation in the control cabinet, if the
film on the front of the HMI device or the glass of the display on the HMI device are
damaged by a tear or hole or if the front film starts to peel off.

Exchange the HMI device. Restart the system again after the device has been
exchanged.

3.1 General information

Proper transport and storage, installation and assembly as well as careful operation and
maintenance are required to ensure trouble-free and safe operation of the HMI device.

The warranty for the HMI device will be deemed void if these stipulations are not heeded.

3.2 Mounting positions and type of fixation

Permitted mounting positions

The HMI device is designed for mounting in stationary cabinets, for example for mobile
drilling rigs and ships.

The HMI device is approved for horizontal mounting. The HMI device can be installed as
follows:

● Vertical

● Inclined at an angle between 0° and 90°

● Horizontal

Temperature Extension Kit

The "Temperature Extension Kit" lets you use the HMI device relatively independent of the
actual ambient conditions. You accomplish this feat because the "Temperature Extension
Kit" creates an environment in the cabinet that is within the limits permitted for operation of
the MP 377 15" Touch daylight readable.

If you are going to equip the HMI device with the "Temperature Extension Kit" option, you
need to select a cabinet of the appropriate size. Make allowances for the fact that the
thermal conductivity of control cabinets made of stainless steel is not as good as that of an
aluminum cabinet, for example.

You will find additional information in the "Temperature Extension Kit" operating instructions.

3.3 Preparation for mounting

Selecting the mounting location for the HMI device

Points to observe when selecting the mounting location:

● Position the HMI device so that it is not subjected to direct sunlight.
The display was designed for operation in direct sunlight.

● Position the HMI device such that it is ergonomically accessible for the user.
Choose a suitable mounting height and mounting angle.

● Make sure that you do not cover the fan and the air vents of the HMI device during
installation.

Ensuring degree of protection

The degree of protection according to the information in the chapter "Technical
Specifications (Page 54)" can only be ensured if the HMI dev

ice is installed with the supplied
mounting clamps. Additional fastening bore holes or threaded bolts are not required for the
mounting cutout.

The front material has to consist of sheet steel or material of a strength that corresponds to
at least the stability of sheet steel.

Mounting cutout

The following conditions apply to the mounting cutout:

Mounting cutout Dimensions
Material thickness with IP66 degree of protection 1.5 to 5 mm
Material thickness with enclosure type 4X/type 12 (indoor use only) 3 to 5 mm
Permitted deviation from plane

This condition must be fulfilled for the mounted HMI device.

≤ 0.5 mm

Permitted surface roughness in the area of the mounting seal ≤ 120 µm (Rz 120)

The following table shows the dimensions of the mounting cutout:

Dimensions HMI device
Width 367+1 mm
Height 289+1 mm
Depth 105.5 mm
