Installation
Warnings
The device is designed to be exposed partly to the fan air stream with
maximum medium temperature of 40°C to achieve full power load at all fan
sizes.
Alternatively, a forced cooling can be realized in any other way, for instance by
additional blower. Otherwise, if the operating conditions cause overheating,
the controller would automatically perform self-derating to operate at the
allowed temperature limit, indicating warning "Temperature derating".
Do not cover the device during operation!
