5 Installation
5.1 Preparation
The CIRCUTOR capacitor banks are prepared for an easy installation and start-up.
Remove the equipment's packaging and verify that the unit's electrical characteristics are
suitable for connection to the available grid. To accomplish this, check the characteristics label
located inside the cabinet, next to the regulator, refer to Fig. 4-1, for an example. Key data to be
checked:
- Grid voltage and mains frequency, U
n
/ f.
- Nominal power of the capacitor bank, Q
n
(kvar) and composition
- Current consumption, I
n
(see label). This current must be taken into account in order to
select the proper size of the equipment's power supply cable and eventually, the circuit
breakers that are to be connected before it.
- Auxiliary control voltage, U
aux
(See section 5.3.3)
- Environmental conditions. (See section 4.3)
5.2 Installation location
It is important to keep a certain distance around the equipment clear of any items in order 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 and other equipment in order to facilitate cooling. Regarding the
sides, it is recommended that a separation of 10 cm be maintained between adjacent equipment.
On wall mounted cabinets, it is recommended that at least 20 cm of separation be maintained
between the sides of adjacent equipment.
Make sure the equipment can be accessed easily.
The environmental conditions of the location where the equipment is installed must not surpass
the limits established in the technical features (See section 4.3)
In order to ensure proper ventilation, the unit must be installed in a vertical position..
in accordance with LVR, once the unit is installed, it must be protected against direct and indirect
contacts; therefore, a circuit-breaker and an earth leakage protection for the capacitor bank's
power supply line should be installed.
5.3 Connection of the capacitor bank to the grid
Check that the nominal voltage of the capacitor bank coincides with the voltage
between phases of the grid where it is being connected. Also check the operating
circuit voltage (contactors). Regarding this issue, refer to section 5.3.3
For feeding cables into the capacitor bank cabinet, always use the entry points
