CIRCUTOR OPTIM HYB Series - Manual (Page 17)

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.
Make sure the unit can be accessed easily.
The environmental conditions of the location where the unit is installed must not exceed the
limits set forth in the technical features (See “ 6.- TECHNICAL FEATURES” )
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 indi-
rect contacts; therefore, a circuit breaker and earth leakage protection for the capacitor bank
power supply line should be installed.
3.4.-CONNECTION OF THE CAPACITOR BANK TO THE MAINS
Check that the rated voltage of the capacitor bank matches the voltage between
phases of the grid to which it is being connected.
For feeding cables into the capacitor bank cabinet, always use the entry point
enabled for this purpose (See Figure 8 showing the cable entry point on OPTIM
HYB 2 models).
If another part of the cabinet is cut out to be used for cable entry, the CIR-
CUTOR manufacturer's guarantee shall be rendered void.
Do not cut holes in other parts of the cabinet for feeding cables through or for
installing support brackets.
It may produce trimmings that can cause short-circuits.
