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.

Analog Input Connection
-
The analog input is not isolated from Aux Supply. A series connection between analog inputs of the units
is not possible
-
With AC Aux supply it’s not possible
connect the zero terminal “7 (-)” of Analog Input to the earth.
-
With DC Aux supply it’s not possible
to connect the zero of the power supply (terminal 1 and 2) with the
zero “terminal 7(-)” of analog input
-
Never connect
terminals “1” and “2” to earth
