ˆ Confront the rectifier module in any of the slots foreseen
for them in the DC Power-S cabinet and insert it with the
needed force in order to connect it to the «Backplane».
There is not risk of error, because the module is guided
by the natural channel of the own compartment and at its
back part side there is a pivot to centre it, which also con-
fers the needed rigidity to avoid that the connectors suffer
mechanical efforts less the ones for its own function of
the electrical contact.

•
All electrical connections and disconnections of cables from
the equipment, including the control ones, will be done with
no power supply and switches on rest position «O» or «Off».
• Before proceeding to fit the batteries in physically check that
protections or switches of the system are in «Off» position,
and in particular the one belonging to batteries in the equip-
ment (F/Q3) and its homologous (F/Q8) in the battery
cabinet, in case there were an external battery set.
When the protection is done by means of fuses, they are sup-
plied inserted in the fuse holder, because the batteries are
not supplied already fitted in the cabinet. This way misleading
and losses are avoided.
• Batteries are always supplied out from the own equipment
cabinet or battery cabinet. Therefore, it will be needed to fit
and connect them in according to the supplied diagram to-
gether with the documentation, by using the supplied acces-
sories like rods, cables and bolts.
Start the procedure by fitting the batteries in the lowest shelf
in order to settle the cabinet and getting the lowest centre of
gravity and go to the next level as soon as the shelf is com-
pletely filled.
• In systems with removable selves, it is mandatory to intro-
duce them as soon as they are filled, therefore unnecessary
mechanical torques over the frame will be avoided, which
can mean structural twists.
ˆ To remove each battery shelf (BB), is needed to remove
the two screws (BL
which are located at the front and in both sides.
Leave the connection between levels for the end,
ˆ
otherwise there is risk of electrical discharge.
ˆ Complete the battery shelves one by one, interconnect
the batteries among them and introduce the battery shelf
in, as soon as the single works in each one of them is
finished.
Put both screws (BL
and tighten them.
ˆ Next, proceed to connect the batteries between levels,
paying attention to the safety instructions stated in this
document and EK266*08.
•
Once the batteries are interconnected, take caution,
because dangerous voltage between the terminals of
several batteries or between one of them and the earth can
exist, depending on the total voltage of the set.
• In systems with back up time 0/ or 0A/, the battery acquisi-
tion, installation and connection will be borne by the client
and under his responsibility. Battery data relating to quantity,
capacity and voltage are stated in the battery label sticked
beside the nameplate of the equipment, respect these data
strictly, the polarity of the battery connection and the sup-
plied circuit diagram together with the documentation and the
DC Power-S.
