Mounting position
The HMI device is suitable for installation in:

Mounting position Deviation from the vertical
① Inclined ≤ 35°
② Vertical 0°
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.
Otherwise, the HMI device may be damaged and the approvals and warranty for the
HMI device may become void.
For information regarding the permissible ambient temperatures, refer to Notes about usage
(Page
