For equipments with floating output:
When the physical protection means a single element (circuit breaker),
there will be one auxiliary contact only, so there will be a single group
of terminals only (X42). If the protection is done by fuses, the will be
two auxiliary contacts, one for each pole, so there will be two groups
of terminals (X42A) and (X42B) for the selective identification, as it is
shown in Fig. 23.
For equipments with the positive or negative output earthed:
In this case, as the protection will be single pole, there will be only one
group of terminals for the auxiliary contact (X42), corresponding to the
alive pole (the one not connected to earth).

7.10. Terminal strip, auxiliary contacts
of the protections of the battery
cabinet.
• As an option the battery protection of the DC Power-S battery
cabinet can incorporate auxiliary contacts (C-NC-NO).
This auxiliary contact is supplied connected to a terminal
strip of double or triple tier (see Fig 24) and they have the
function to inform about the tripping or manoeuvring of the
protections. This information can be used to trigger , i.e., an
external alarm owned by the client.

The voltage and current features that can support these con-
tacts are 250 V AC 1 A. Use cables of 1 mm
as minimum, but better to use 2,5 mm
the auxiliary terminals.
• Table 3 shows the correlation of the auxiliary terminals with
the function of the protection. If the equipment does not have
the auxiliary contact ignore that reference.
