CIRCUTOR OPTIM P&P Series - Manual (Page 9)

Do not access the active elements of a capacitor bank with static operation that
has been powered and might have voltages present. Wait at least 5 minutes af-
ter the power supply has been disconnected.
Do not touch the terminals or active parts of the unit until you have verified that
voltage is not present. If you have to handle or touch the terminals or other control
panel components, use adequately insulated personal protection equipment and
tools.
After any maintenance and before re-connecting the power supply to the unit,
check that its enclosure is properly closed and that no items or tools were left
inside that could cause a short-circuit.
Do not disconnect the current transformer secondary without short-circuiting it
first. The operation of a current transformer with an open secondary will cause an
overvoltage that could damage it and electrocute the person handling it.
3.2.- PREPARATION
The CIRCUTOR OPTIM P&P static capacitor banks come ready for easy installation and start-
up.
Remove the packaging of the unit and verify that its electrical features are suitable for connec-
tion to the available mains. To do so, check the features label located inside the cabinet next to
the FP regulator, see Figure 3 .
Key data to be checked:
 Mains frequency and voltage, U
n
/ f
n
.
 Nominal power of the capacitor bank, Qn (kvar) and composition
 Current consumption, I
n
. This current must be considered to select the proper size
of the power supply cable of the unit and ultimately the circuit breakers and protection
elements to be connected in front of it.
 Auxiliary control voltage, U
aux
.( See “3.7.- AUXILIARY CONTROL VOLTAGE” )
 Environmental conditions. (See “6.- TECHNICAL FEATURES”)
