Communication Module - Salicru DC POWER-S DC-36-S User Manual

7.7.2. With DC outgoing distribution.
Terminals (X6A.. 6*) and (X9A.. 9*).
7.7.2.1. Floating output.
•
All protections or switches of the system has to be in «Off»
position, and in particular the one belonging to batteries in
the equipment (F/Q3) and its homologous (F/Q8) in the
battery cabinet, in case there were an external battery set.
•
Connect the loads to the two poles protections of the out-
going distribution terminals directly, considering the current
limit of each one of them and the own connected load. As an
option an outgoing terminal strip can be supplied. Both has
the connection points labelled in Fig. 5 to 8 as (X6A.. 6*) and
(X9A.. 9*).
Respect the colour of the cables (red for positive and black
for negative) and the polarity stated in the labelling of the
equipment.
• Connect the earth of load or loads to the earth terminal or
rod (X5).
7.7.2.2. Output with positive earthed.
• All protections or switches of the system has to be in «Off»
position, and in particular the one belonging to batteries in
the equipment (F/Q3) and its homologous (F/Q8) in the
battery cabinet, in case there were an external battery set.
•
Outgoing distribution:
ˆ By default to the protection terminals.
Connect the negative of the loads to the single pole pro-
tections of the outgoing distribution terminals directly
(X9A.. 9*), considering the current limit of each one of
them and the own connected load.
Connect the positive of the loads to the common rod,
which has several bolts as terminals (X6A.. 6*) and at the
same it is connected to earth.
ˆ Terminal strip as an option.
An outgoing terminal strip can be supplied with the cor-
responding negative terminals to each protection (X9A..
9*). Connect the negative of the loads to these ter-
minals.
Connect the positive of the loads to the common rod,
which has several bolts as terminals (X6A.. 6*) and at the
same it is connected to earth.
Respect the colour of the cables (red for positive and black
for negative) and the polarity stated in the labelling of the
equipment.
•
Connect the earth of load or loads to the earth terminal or
rod (X5).
7.7.2.3. Output with negative earthed.
• All protections or switches of the system has to be in «Off»
position, and in particular the one belonging to batteries in
the equipment (F/Q3) and its homologous (F/Q8) in the
battery cabinet, in case there were an external battery set.
•
Outgoing distribution:
ˆ By default to the protection terminals.
Connect the positive of the loads to the single pole pro-
tections of the outgoing distribution terminals directly
(X6A.. 6*), considering the current limit of each one of
them and the own connected load.
Connect the negative of the loads to the common rod,
which has several bolts as terminals (X9A.. 9*) and at the
same it is connected to earth.
34
ˆ Terminal strip as an option.
An outgoing terminal strip can be supplied with the corre-
sponding positive terminals to each protection (X6A.. 6*).
Connect the negative of the loads to these terminals.
Connect the negative of the loads to the common rod,
which has several bolts as terminals (X9A.. 9*) and at the
same it is connected to earth.
Respect the colour of the cables (red for positive and black
for negative) and the polarity stated in the labelling of the
equipment.
• Connect the earth of load or loads to the earth terminal or
rod (X5).
7.8.

Communication module.

•
The system has a communication module described in the
user's manual EN030*. This module has two versions, the
basic on, which is included in all DC Power-S systems as
standard and the extended one.
7.9. Terminal strip, auxiliary contacts of
the protections of the system.
•
As an option the DC Power-S can incorporate auxiliary
contacts (C-NC-NO) in any of the standard protections or
switches of the equipment -Input, Output and Batteries- and/
or in any of the options -Single input protection for each recti-
fier, single output protection for each rectifier, General out-
going distribution and/or outgoing distribution-.
These auxiliary contacts are supplied connected to a ter-
minal strip of double or triple tiers (see Fig 23) and they have
the function to inform about the tripping or manoeuvring of
any protections or switches. 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 2 shows the correlation of the auxiliary terminals with
the function of the protection or switch. If the equipment
does not have auxiliary contacts in any of the protections or
switches, ignore that reference and proceed with the rest of
connections.
