3.3
Installation locations and type of protection
Installation location
The HMI device is designed for installation in the front panels of cabinets and consoles. The
MP 270B 10" Keys and OP 270 10" are also designed for installation in 19" cabinets and
racks.
Cut an installation cut-out in a front panel. The thickness of the front panel must not exceed
6 mm. Additional holes for securing the HMI device are not necessary because a clamping
mechanism is available.
Degree of protection
Install the HMI device Install the HMI device to meet the minimum requirements for IP54
degree of protection. The IP65 degree of protection for the front panel can only be ensured
when the seal on the front plate of the HMI device is fitted correctly.
Notice
The NEMA 4 or IP65 degrees of protection are only ensured when
- in the case of MP 270B 6", OP 270 6" or TP 270 6", the plate thickness of the installation
support is at least 2 mm
- in the case of MP 270B 10", OP 270 10" or TP 270 10", the plate thickness of the
installation support is at least 2.5 mm
Caution
The systems ability to be waterproof and dustproof as per the section "Approvals" is only
guaranteed when the following is met:
•
Material thickness of installation cut-out: 2 to 6 mm (MP 270B 6", OP 270 6" or TP 270 6") and 2.5
to 6 mm (MP 270B 10", OP 270 10" or TP 270 10")
•
Deviation of the installation cut-out from the horizontal related to the overall dimensions of the HMI
device: = 0.5 mm
•
Permissible surface roughness in the area of the seal: max. 120
