3.1.2
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 169)
–
Electromagnetic compatibility (Page 172)
2.
Check the mechanical and climatic ambient conditions for operation of the HMI device:
Ambient conditions (Page 196).
3.
Follow the instructions for local use of the HMI device: Notes about usage (Page 27).
4.
Adhere to the permissible rated voltage and the associated tolerance range:
–
Rated voltage: +24 V DC
–
Tolerance range: 19.2 V to 28.8 V
3.1.3
Selecting a mounting position
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 HMI device is self-ventilated and approved for inclined mounting at angles up to +/-35°
in stationary cabinets.
CAUTION
Damage due to overheating
An inclined installation reduces the convection by the HMI device and therefore the
maximum permissible ambient temperature for operation.
If there is sufficient forced ventilation, the HMI device can also be operating in the inclined
mounting position up to the maximum permissible ambient temperature for vertical
installation. The HMI device may otherwise be damaged and its certifications and warranty
will be void.
For information regarding the permissible ambient temperatures, refer to Ambient conditions
(Page 196).
