Salicru DC POWER-L Series, Manual

18

When the protection consists of fuses, these are supplied 

already inserted into the fuse holder base, as the batteries 

themselves are not delivered already installed in the cabinet. 

This way, any loss or mislaying is avoided.

• 

The batteries are always supplied in packaging separate to 

the device cabinet or accumulator cabinet or cabinets. Con-

sequently, it will be necessary to install and connect them 

according to the connection diagram supplied with the docu-

mentation, using the accessories provided, such as strips, 

cables and screws.
Start the process by placing the batteries in the lower tray to 

secure the cabinet, ensuring that the centre of gravity is as 

low as possible, and work your way up as the trays are filled.

• 

In systems with removable trays, it is advisable to insert 

them as they fill up, thus avoiding unnecessary mechanical 

stresses on the frame itself, which can lead to structural tor-

sion.

ˆ

To remove each battery tray, it is necessary to remove 

the two screws

 that fix it like a mechanical lock located 

on either side of the front.

ˆ

Wait until the end to connect the end cables be-

tween levels, otherwise there is a risk of electric 

shock.

ˆ

Fill up the trays with the accumulators one by one, inter-

connect the batteries between them and insert each tray 

as individual tasks are completed on each of them.
Fit the two screws

which act as a lock and tighten them.

ˆ

Then connect the batteries between levels, observing 

the safety instructions indicated in this document and in 

EK266*08.

• 

Dangerous voltages stored in batteries

: Precau-

tions must be taken with the batteries once intercon-

nected, as there may be dangerous voltage between the 

terminals of different batteries or between one of them and 

the earth, depending on the total voltage of the bank, in-

cluding when the device is disconnected.

• 

In systems with 0/ or 0A/ backup, the acquisition, installation 

and connection of batteries will always be carried out 

under 

the responsibility

 of the customer. Information concerning 

the batteries in terms of number, capacity and voltage is indi-

cated on the battery label affixed next to the device’s name-

plate. 

Strictly observe

 this information, the connection 

polarity of the batteries and the connection diagram supplied 

with the documentation and the DC Power-L.

• 

Any handling and connection of the batteries should 

only be carried out or supervised by 

suitably quali-

fied personnel

.

Before carrying out any action, disconnect the batteries. 

Check that no current is present and that there is no dan-

gerous voltage at the ends of the terminals of the battery 

bank.
The battery circuit is isolated from the input voltage of devices 

with floating output voltage, but not from devices with output 

voltage referenced to earth. Dangerous voltages can occur 

between the terminals of the battery bank and the earth.
Check that the system does not have input voltage before 

working on the batteries, otherwise the rectifier will supply 

DC voltage to the cables connected to the accumulator bank, 

with the resultant risk.

• 

It should never be forgotten that the DC Power-L with 

batteries is a generator of electrical power, regardless 

of whether the batteries are installed in the same cabinet or in 

the device itself, so the user must take all necessary precau-

tions against direct or indirect contact.

If the batteries are connected to the device and its protec-

tions are set to ‘On,’ it is irrelevant whether or not the DC 

Power-L is connected to the power supply, as is the state or 

position (On or Off) of its protection.
The output terminals will supply voltage while the battery 

bank has power, unless the output disconnector switch 

(Q2)

is ‘Off’ or, if there is output distribution, the general protection 

of the output distribution or each of the individual output dis-

tribution protections is set to ‘Off.’

• 

Dangerous voltages stored in capacitors

:

Precau-

tions must be taken as charged capacitors with dan-

gerous voltages may be installed between the connection 

terminals or between one of them and earth, even when the 

device is switched off. Wait 30 seconds or more to allow 

these to discharge.

7.2.  Considerations to take into 

account.

• 

The location should be spacious, airy and easily accessible. 

The slots of the ventilation should never be obstructed, nor 

should the device be installed outdoors.

• 

The cross sections of the input, output and earth cables must 

be in accordance with the rated current indicated on the 

nameplate, and compliance with the country’s regulations 

and legislation is an essential requirement.

• 

A bad connection or operation can cause faults in the device 

and/or the loads connected to it. Read the instructions in this 

manual carefully and follow the steps indicated in the order 

established.

• 

The base of the cabinet features a number of wall bushings 

(cable glands, Fig. 2), to isolate the routing of the connection 

cables through the metal sheet of the cabinet.
Cut them to the appropriate section to enable the respec-

tive input, output and battery cables to pass through them in 

models with the accumulators in a separate cabinet.
Upon request, some cabinets can have a slot to serve as a 

conduit for cable entry, instead of the wall bushings.

• 

All of the cables will be fixed to the bar by clips in order to im-

mobilise them and prevent possible pulling that could lead to 

false contacts, cable disconnection, etc., and consequently, 

to failures of the device and/or possible accidents due to 

electric shock.

7.3.  Earth connection, terminal or 

strip  .

• 

It is advisable, 

and so required by

 the regulations or legisla-

tion of the country, to 

connect the device to earth

.

Make sure that all of the device’s loads are only connected 

to earth in the form of a terminal or strip. Failure to limit the 

earthing of the loads to this 

single point

 would create earth 

return loops and degrade the quality of the power supplied.
All terminals identified as an earth connection 

( )

 are linked 

together and to the earth of the cabinet.

• 

For models with batteries in a separate cabinet, connect 

the terminal or strip 

of the earth of the rectifier, to the earth 

bonding terminal

( )

 of the accumulator cabinet, using the 

cable provided in the battery connections hose.
