Circutor OPTIM HYB Series, Инструкция по эксплуатации

Страница: 16 / 36

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 HYB 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 regulator, see
Figure 7
.
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
max
. 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.

Environmental conditions. (See “
6.- TECHNICAL FEATURES”
)
Figure 7: Features label.
3.3.- INSTALLATION LOCATION
It is important to maintain a minimum distance around the unit to facilitate cooling.
In self-supporting cabinets, the back and front sides of the cabinet must be kept at least 50 cm
away from walls of other units and other infrastructure to allow for ventilation.
In terms of the side walls, it is recommended that a separation of 10 cm be maintained between
adjacent cabinets.
On wall-mounted cabinets, it is recommended that at least 20 cm of separation be maintained
between the sides of adjacent cabinets.
Note: Hybrid units have aluminium heatsinks to cool the thyristors. Periodically clean these
radiators with a brush or with compressed air and ensure that they have maximum ventilation.
