CSPF-100 : Power Factor Controller
If the system is not put into service immediately, it must be stored in a dry location at a temperature
0 0
between -10 C to +70 C
Please check the phase & polarity while inserting the CT wire, Wrong polarity or phase can cause the
wrong result (may cause wrong power factor measurement)
On receipt of the device check that it has not been damaged during delivery and the model supplied is
the same as the one ordered
For the safe use of CSPF-100, it is vital that those persons installing or handling it, follow the usual
safety procedures as well as specific warnings contained in the QRG
Installation, maintenance and inspection of the product should be performed by the qualified staff
Verify that voltage range for the device supplied matches the mains voltage where it is to be installed
Do not install CSPF-100 near to source of heat and do not expose to a excessively humid atmosphere
Verify correct terminal connection when wiring. Wrong connection may cause damage to the product
Check that the secondary windings of external CT is short-circuited when they are not terminated to
CT terminals of CSPF-100. An open secondary windings of a loaded CT may cause dangerous over voltage.
Turn off the all power sources connected to the device, before installing or services to prevent
Bear in mind that when the device is in operation, the terminals may be dangerous when touched
electric shocks, injury or damage to persons or property

Connection
To safely use of CSPF-100, it is important that people installing or handling it, follow the usual
safety precautions.
• Care must be taken with the capacitors, which may be charged and may discharge even after
voltage is removed. Ensure that the capacitors have had time to discharge.
• The current transformer (CT) to be installed at a point where all of the load currents to be
corrected plus the capacitor current are passing. The CT must be installed in any one of the
three phases (Refer Connection Scheme).
• The device must be connected to a power supply circuit and capacitor bank connections
protected with fuse of suitable rating.
• Make sure that correct discharge resistors are fitted to capacitor bank terminals for safety
reason. They are required for discharging capacitor voltage.
