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 mains to which it is being connected.

For more information see section “

3.2.- PREPARATION

and check the label for

the voltage value

Un and the rated frequency fn of the EMS-C capacitor bank.

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.

3.5.-POWER CIRCUIT

Connect input terminals L1, L2 and L3 (power circuit) to the mains using a cable with a suitable

cross-section, in accordance with the LVR, ITC-BT-19.

Generally, the cables of the phases are according to the following colour code: L1 (black), L2

(brown), L3 (grey).

To determine the size of the phase cables, the maximum nominal current I

max

shown on the unit

label, and a transients overload of up to 1.5 times I

max

must be taken into account.
