Control description
• OK RELAY
The OK relay has a normally open contact which close at the end of the precharg-
ing phase if no alarm condition is present (overtemperature, power supply on the
regulation card ±15V).
The contact is closed during the normal functioning of the device and also during
an undervoltage situation. The contact opens when a failure occurs (see the alarm
conditions described above) or when the power supply is switched off and the DC-
LINK is completely discharged (C and D terminals).
