For connection or disconnection of the

is required.
The UVR of the external breaker must be
connected to terminal XA (see Fig. 4.1.7-1).
The release signal will allow, after the
Rectifier soft-start, the manual closure of
the breaker.
In either case, fuses or breaker, an auxiliary contact must signalize the closure of breaker or fuse
holder to Input channel 1 of the P4 - Customer Interface (see Section 4.1). When multiple strings /
cabinets are used, the auxiliary contacts from the breakers are to be connected in series.
Contact must be open with Battery disconnected (Normally Open).
