Installation and putting into service

Measurement and supply voltage

The controller Prophi can be delivered in two connec-
tion varieties for the measurement and supply voltage.
In the version measurement L-L, the measurement and
supply voltage must be taken from two outer conduc-
tors. In version measurement L-N, the measurement
and supply voltage must be taken between outer con-
ductor L and neutral N.
Before connection, please ensure, that the local net con-
ditions match the data on type plate. The range of the
measurement and supply voltage is given by the type
plate and is connected via a fuse (2...10A, time lag type)
Attention!
c
The measurement and supply voltage must
come from the low voltage net, which is su-
pervised.
The connected measurement and supply voltage may
not exceed the voltage, mentioned on type plate for
more than 10% or underscore for more than 15%.
To ensure, that the connected measurement and supply
voltage is within the allowed range, please check the
voltage at the terminal with a voltmeter.
Attention!
c
Voltage, which is out of the indicated range
on type plate can destroy the instrument.
If the measurement and supply voltage is within the
allowed range, Prophi indicates the voltage on the ter-
minal.
While measuring via voltage transformers, the voltage
transformer ratio must be programmed.
Attention!
c
The operating voltage for the contactors should
be received from an outer conductor connected
to the controller.
