Section 2 Installation and connection of the controller
The controller is designed to be incorporated into the front panel of a PFC-cabinet. It
requires a switchboard section of 138 x 138 mm to DIN 43700/ IEC 61554. The controller
is inserted from the front and is attached by means of the appended clamps. It may
be inserted only by qualified technicians and must be operated in accordance with the
specified safety regulations.
Before the Prophi-6R is connected up, all leads and cables must be checked to ensure that
no current is flowing through them and the current converter must be short-circuited.
Care should be taken to ensure that the measuring voltage and current are in the correct
phase position. The measuring-current circuit must be wired with copper leads of
2
2.5mm . The connection should be set up as shown in Fig. 3. The specified safety
regulations must be observed.
The measuring voltage may lie in the range from 30 - 525 VAC and can be connected
between L - N ( default ) or between L - L (programming of phase correction needed)
The supply voltage is 110...230 VAC +/- 15% and can be connected between L - N or
L -L (depending of the grid).
The coil voltage for the capacitor contactors and the measuring voltage
must be drawn from the same phase conductor, as only the measuring
voltage is monitored. (Protection against direct reconnection of the
capacitor contactors in the event of momentary single-phase power
failure)
