Checking the operating conditions 
Note the following aspects before installing the HMI device: 
1.  Familiarize yourself with the standards, approvals, EMC parameters and technical 
specifications for operation of the HMI device. This information is available in the 
following sections: 
–  Certificates and approvals (Page 183) 
–  Electromagnetic compatibility (Page 188) 
2.  Check the mechanical and climatic ambient conditions for operation of the HMI device: 
Technical information (Page 183). 
3.  Read the notes on the local use of the HMI device: Notes about usage (Page 30). 
4.  Note the permissible rated current: +24 V DC 
 
Permitted mounting positions 
The HMI device is suitable for installation in: 
●  Mounting cabinets 
●  Control cabinets 
●  Switchboards 
●  Consoles 
In the following, all of these mounting options are referred to by the general term "cabinet". 
The device is self-ventilated and approved for inclined mounting at angles up to +/-35° from 
the vertical. 
 
Damage due to overheating 
An inclined installation reduces the convection by the HMI device and therefore the 
maximum permitted ambient temperature for operation. 
If there is sufficient convection from forced ventilation, the HMI device can also be operated 
in the inclined mounting position up to the maximum permitted ambient temperature for 
vertical mounting. The HMI device may otherwise be damaged and its certifications and 
warranty will be void. 
The working temperature ranges listed in this section apply to the rear and the front of the 
HMI device. 
For detailed information regarding the permitted ambient temperatures, refer to section 
"Climatic ambient conditions (Page 190)".
