Section 3 Installation and connection of the controller
The controller is designed to be incorporated into the front panel of a PFC-
cabinet. It requires a panel cutout of 92 x 92. The controller is inserted from
the front and it gets fitted into panel with help of self clicking & if required
swivel screw can be used.The controller should be installed by qualified
technicians and must be operated in accordance with the specified safety
regulations.
Mounting of the controller is featured with easy “Clip- in” mounting. Push the
meter in panel slot, it will click fit into panel with the four integral retention
clips on two sides of meter. If required, additional support is provided with
swivel screws as shown in Fig. 1
Before the controller is connected up, all leads and cables must be checked to
ensure that no current is flowing through them. Care should be taken to
ensure that the measuring voltage and current are in the correct phase
position. The connection should be set up as shown in Fig. 2. The specified
safety regulations must be observed.
The auxilliary supply voltage is 110 to 550 VAC / DC
The measuring voltage may lie in the range from 30-550 VAC and can be
connected as L-N or L-L. after voltage and current connections enter CT
primary and secondary.
Now as per site conditions Phase correction angle,voltage
type,Capacitor bank KVAr ,Number of capacitor banks parameters can
be set OR Auto initialisation can be carried out to detect above parameters.
Auto-initialisation function designed to works in most of practical load
conditions and system networks. Refer Auto initialisation notes for detail.
if any ambiguty found in system values during or after autoinitilisation then
settings for above can be done in basic settings and advanced system
settings.
