2.2.7 General Information
Ear Protection
The device fans and the power module create significant levels of operating noise. In addition to this,
a fault in the device can lead to very high sound levels.
Burns
Immediately after isolating the device, depending on the operating conditions, certain components
can be very hot (e.g. fuses, transformer core, sinusoidal filter, heat sinks etc.).
Safety gloves should always be worn when working near components that can be expected to be
very hot.
High noise levels in electrical operating rooms
We recommend the use of ear protection when in the vicinity of the Sunny Central
operating room for extended periods.
High temperature on device parts
We recommend that safety gloves be worn during all work on the device.
