What is the significance of two arrows on the knob of Tesys GV3P Current Setting Dial.

The first black arrow needs to be set at the rated current of Motor, when Tesys GV3 MPCB is used with contactor separately mounted or not used at all.
 
The second white arrow needs be set at rated current of Motor, when the Tesys GV3 MPCB and contactor are used in combination. This setting gives allowance for the heat dissipation in the thermal characteristics of MPCB due to the combined use of the Tesys GV3P and Tesys LC1D at the rated current.
 
See below diagram for clarity.
