IMPORTANT
Before connecting and using this product, please read this instruction manual carefully
and keep it on hand for future reference.
The manual is to be considered an integral part of this product and must accompany it
when it changes ownership as a reference for correct installation and use as well as for
the safety precautions.
RCF S.p.A. will not assume any responsibility for the incorrect installation and / or use of
this product.
WARNING: To prevent the risk of re or electric shock, never expose this product to rain
or humidity.
SAFETY PRECAUTIONS
1. All the precautions, in particular the safety ones, must be read with special attention,
as they provide important information.
2.1 POWER SUPPLY FROM MAINS
- The mains voltage is sufciently high to involve a risk of electrocution: never install or
connect this product when its power cord is plugged in.
- Before powering up, make sure that all the connections have been made correctly and
the voltage of your mains corresponds to the voltage shown on the rating plate on the
unit, if not, please contact your RCF dealer.
- The metallic parts of the unit are earthed by means of the power cord.
- An apparatus with CLASS I construction shall be connected to a mains socket outlet
with a protective earthing connection.
- Protect the power cord from damage. Make sure it is positioned in a way that it cannot
be stepped on or crushed by objects.
- To prevent the risk of electric shock, never open this product: there are no parts inside
that the user needs to access.
- The mains plug is used as the disconnect device and it shall remain readily operable.
2.2 BATTERIES
- Operating voltage is 48 V dc (therefore, it is necessary to connect in series several
batteries having a lower nominal voltage, example: 4 x 12 V).
- Always use rechargeable batteries, which need to be chosen according to the maximum
possible load.
- Verify the polarity of batteries is correct.
- Do NOT short-circuit batteries (i.e. connecting the 2 opposite poles together with
metallic wires).
- Throw empty batteries away according to your country laws about ecology and
environment protection.
3. Make sure that no objects or liquids can get into this product, as this may cause a
short circuit.
This apparatus shall not be exposed to dripping or splashing.
No objects lled with liquid (such as vases) and no naked sources (such as lighted
candles) shall be placed on this apparatus.

ENGLISH
4. Never attempt to carry out any operations, modifications or repairs that are not
expressly described in this manual.
Contact your authorized service centre or qualified personnel should any of the
following occur:
- The product does not function (or functions in an anomalous way).
- The power cord has been damaged.
- Objects or liquids have got in the unit.
- The product has been subject to a heavy impact.
5. If this product is not used for a long period, disconnect both the power cord and
batteries.
6. If this product begins emitting any strange odours or smoke, switch it off immediately
and disconnect both the power cord and batteries.
7. Do not connect this product to any equipment or accessories not foreseen.
For suspended installation, only use the dedicated anchoring points and do not try to
hang this product by using elements that are unsuitable or not specic for this purpose.
Also check the suitability of the support surface to which the product is anchored (wall,
ceiling, structure, etc.), and the components used for attachment (screw anchors, screws,
brackets not supplied by RCF etc.), which must guarantee the security of the system /
installation over time, also considering, for example, the mechanical vibrations normally
generated by transducers.
To prevent the risk of falling equipment, do not stack multiple units of this product unless
this possibility is specied in the user manual.
8. RCF S.p.A. strongly recommends this product is only installed by professional qualied
installers (or specialised rms) who can ensure correct installation and certify it according
to the regulations in force.
The entire audio system must comply with the current standards and regulations
regarding electrical systems.
9. Supports and trolleys
The equipment should be only used on trolleys or supports, where necessary, that are
recommended by the manufacturer. The equipment / support / trolley assembly must be
moved with extreme caution. Sudden stops, excessive pushing force and uneven oors
may cause the assembly to overturn.
10. Do not obstruct the ventilation grilles of the unit. Situate this product far from any
heat sources and always ensure adequate air circulation around the ventilation grilles.
11. Do not use solvents, alcohol, benzene or other volatile substances for cleaning the
external parts of this product. Use a dry cloth.

RCF S.P.A. THANKS YOU FOR PURCHASING THIS PRODUCT, WHICH HAS BEEN
DESIGNED TO GUARANTEE RELIABILITY AND HIGH PERFORMANCES.
DESCRIPTION
PS 6048 is a backup power supply unit suitable to get continuity power supply for EN 5416 system units (e.g. DXT 9000 and DXT 7000EN systems).
PS 6048 needs to be equipped with lead-acid batteries and includes recharging and
monitoring functions.
INSTALLATION
Fix the unit to a 19” rack cabinet through 4 screws.
According to EN 54-16 standard, the backup power supply unit shall be installed into the
same rack cabinet where there is the audio system with emergency purposes (or a system
part) to which it is connected.

In normal operating mode: the PS 6048 recharges batteries (and maintains them when
they are fully charged).
The maximum total output current that can be supplied continuously (I max a) while
charging batteries is given by:
I n: nominal output current (12 A)
C: battery capacity [A h]
19” rack - 2U

ENGLISH
I max b = I n
I max c = 150 A / 100 A
When the mains supply is available, the maximum total output current that can be
supplied for a short period of time (I max b) corresponds to the nominal value (12 A).
During this time, batteries are not charged (nor discharged).
When the mains supply is NOT available (backup operating mode), the maximum total
output current that can be supplied from batteries (I max c) is either 150 A if the internal
jumper is set to ‘75’ or 100 A if set to ‘50’.
a) I max c = 150 A
Set the internal jumper to ‘75’ and use batteries with a capacity of 86 to 225 Ah.
b) I max c = 100 A
Set the internal jumper to ‘50’ and use batteries with a capacity of 65 to 225 Ah.
The jumper factory setting is the ‘75’ position. Any other jumper setting is like the ‘50’
position.

BATTERY WIRING INSTRUCTIONS
APPROVED BATTERY MODELS:
- Yuasa NPL series
- Powersonic GB series
- ABT TM series
- Enersys VE series
- Effekta BTL series
- Long GB series.
It is advised to secure batteries with a (low resistance, gG curve) fuse, chosen according
to maximum current.
The battery temperature sensor shall be placed as close as possible to batteries, but it
does not need to be in contact with them. For example, it may be xed on the battery
cables.
The PS 6640 checks the battery resistance (including connections) every 4 hours.
The fault threshold resistance value is either 32 mΩ ±10% if the jumper is set to the ‘75’
position or 48 mΩ ±10% if set to the ‘50’ position. Exceeding this threshold is signaled
as a battery fault: batteries will not have the required backup duration in case of mains
power cut.
To avoid possible false fault indications, use battery cables as short as possible and with
large cross sections (35 mm² max).
Approximately, the resistance per metre of a cable (with two copper wires) is:
- 3.6 mΩ/m (10 mm² section)
- 2.3 mΩ/m (16 mm² section)
- 1.5 mΩ/m (25 mm² section)
- 1.1 mΩ/m (35 mm² section).
