1) Set all the switches in off position (18-seconds ramp time), use a current probe able to detect a current
peak
≤≤≤≤≤
10mS between the C or D terminal of the DC-LINK.
2) At this point read the measuring of the maximum peak current present on the DC-LINK during the precharging
phase.
3) If the measured peak current is much lower than twice the value of the CS300 rated current, it is possible to
select the switch for a lower ramp time (SW3.4 - 8- second ramp time). Go back to point 2.
Such operation will be repeated till the measured peak current is equal or lower than twice the value of the
converter rated current.
3.5 USE OF S4 AND S5 DIP SWITCH
The S4 and S5 dip switches are used to select the AC mains frequency.

3.6 USE OF CV JUMPER
(See the ML signal function)
With “CV” jumper mounted (on), the signal available on the terminal 36 will be LOW with AC mains voltage
lower than the undervoltage threshold (see figure 3). It will be HIGH, with AC mains voltage higher than the
undervoltage threshold.
With “CV” jumper open (off), the signal on the terminal 36 will indicate, with an impulse of about 150ms, (low
level signal) that the power supply voltage has had a transition at a level lower than the undervoltage threshold.
