Caution:
this procedure must be performed only by qualified persons.
Note:
*
1 A suitable device must ensure that the unit can be electrically isolated from the supply (electromagnetic
circuit breaker or by fuse isolator), this allows the qualified people to work in safety.
*
2 Only for the HB option See par. “Heater break Alarm and SCR short circuit”.
*
3 The heat-sink must be connected to the earth.
*
