In accordance with the LVR, once the unit is installed, the installation must be protected against direct and indirect contacts. Therefore, a circuit breaker and earth leakage protection for the capacitor bank power supply line should be installed.
For feeding cables into the capacitor bank cabinet, always use the entry point enabled for this purpose, located on the left side of the cabinet base (relative to the front panel). 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.
The capacitor bank has a manual internal four-pole isolator, but it must be connected to a line that is protected by a circuit breaker as well as earth leakage protection at the header, in ac-cordance with Spanish Low-Voltage Electrotechnical Regulations (LVR) and depending on the earthing system of the installation.
If the unit is supplied with a disconnect, the incoming conductors are connected directly to the disconnect's line lugs. The lugs shall be torqued as indicated on these devices. Fused disconnects should be sized no less than 165% of the rated capacitor current. The circuit breaker should be sized no less than 135% of the rated capacitor current.
