Power Factor Correction Systems
Commissioning and Maintenance
General
FRAKO power factor correction systems are prewired and receive
a thorough individual inspection to verify the good working order of
all components before leaving the factory.
Before commissioning the system it is only necessary to connect
the power supply and the cabling to the current transformer. The
current transformer itself, however, is not included in the scope of
supply for power factor correction systems.
The reactive power control relay must be adjusted according to the
separate operating manual supplied with the instrument.
Any questions that may arise concerning the wiring and commissi-
oning of the system are treated in detail in these instructions.
Safety instructions
Caution: Dangerous voltages are exposed inside the cabinet.
Every operation that involves opening the door may therefore only
be made by a qualied electrician.
The installation of the power factor correction system, the verica-
tion of its good working order and any actions taken to rectify faults
may only be carried out by appropriately qualied specialists who
have received instruction on the electrical hazards involved.
All other actions can be carried out by persons who have familia-
rized themselves with these instructions and the operating manual
for the reactive power control relay and follow them at all times.
n
These instructions and the operating manual for the reactive
power control relay must be read through carefully before the
system is installed, connected up and commissioned.
n
The power factor correction system must always be earthed.
n Do not install the system near to any liquids, and do not expo-
se it to an excessively humid atmosphere.
n
If the power factor correction system is visibly damaged, it
must not be installed, connected up or commissioned.
n
Do not cover the ventilation grille.
n Do not expose the system to direct sunlight or install it near to
a source of heat.
n
If the system is not put into service immediately, it must be
stored in a dry location at a temperature between - 20 °C and
+ 60 °C.
n Please observe all current statutory regulations governing the
recycling of the packaging materials.
