The device should, as far as possible, always be switched on using the rotary switch on the front of the device. 

Alternatively this can take place using an external cutout (contactor, circuit breaker) of suitable current capacity. 
After switching on, the display will first show the company logo, followed by manufacturer’s name and address, 

device type, firmware version(s), serial number and item number (approx. 3 s). In setup (see section „3.4.3. Con-

figuration via MENU“ in the second level menu “

General settings” is an option “Input after power ON” in which 

the user can determine the condition of the DC input after power-up. Factory setting here is “

OFF”, meaning that 

the DC input on power-up is always switched off. “

Restore” means that the last condition of the DC input will be 

restored, either on or off. 
All set values are, DC input condition and master-slave operation mode are restored. 

On switch-off, the last input condition and the most recent set values and input status, as well as activated master-

slave operation are saved. Furthermore, a PF alarm (power failure) will be reported, but has to be ignored here.
The DC input is immediately switched off and after a short while fans will shut down and after another few seconds 

the device will be completely powered off.

The MENU serves to configure all operating parameters which 

are not constantly required. These can be set by finger touch on 

the MENU touch area, but only if the DC input is switched OFF. 

See figure to the right.
If the DC input is switched on the settings menu will not be shown, 

only status information.
Menu navigation is by finger touch. Values are set using the rotary 

knobs. The assignments of the rotary knobs, if multiple values can 

be set in a particular menu, are shown on the menu pages in the 

lower middle.

The menu structure is shown schematically on the following pages. 

Some setting parameters are self-explanatory, others are not. The 

latter will be explained on the pages following.
