t1: 5,2 s;
time for internal booting until Bb1 contact closes
t2: time can be set by the user
t3: 400 ms;
time for internal test routine before loading the DC bus
t4: time depends on DC bus capacitance (internal, external) and supply
voltage. The approximate time can be calculated:
t4 = 0,7 x U
Mains

DC bus
t5: 500 ms;
delay time until mains contactor closes
t6: max. 200 ms;
depends on device (ON delay of mains contactor)
