Planning application
Permitted mounting positions
The HMI device is designed for mounting in control cabinets:
The HMI device is approved for horizontal mounting.
The following vertical mounting positions are permissible:
● Vertical
● Inclined at an angle between 0° and 90°
● Horizontal
Use in extended temperature range
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 can find additional information in the "Temperature Extension Kit for MP 377 15" Touch daylight readable"" operating
instructions.
Preparation for mounting
Mounting cut-out
The following conditions apply to 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
Material thickness with IP65 degree of protection
Material thickness with enclosure type 4X/type 12 (indoor use only)
Permitted deviation from plane
This condition must be fulfilled for the mounted HMI device.
Permitted surface roughness in the area of the mounting seal
