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 185)
– Electromagnetic compatibility (Page 188)
2. Check the mechanical and climatic ambient conditions for operation of the HMI device:
Technical information (Page 185).
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
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 of up to +/-
35° in stationary cabinets.
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 installation. The HMI device may otherwise be damaged and its certifications and
warranty will be void.
